INTRODUCTION

11 General Overview

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

Al-Shannagb 2012) From figure 11 the graph shows the rate of world population

and oil production whereas the rate of world population increases as the oil

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

111 Stage 3 Set up an experiment

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

LITERA TURE REVIEW

21 Introduction

In this chapter all relevant infonnation regarding renewable energy nonshy

renewable energy and the vital physical element in the blend of ethanol and gasoline

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

111 Stage 3 Set up an experiment

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

21 Introduction

In this chapter all relevant infonnation regarding renewable energy nonshy

renewable energy and the vital physical element in the blend of ethanol and gasoline

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

INTRODUCTION

11 General Overview

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

Al-Shannagb 2012) From figure 11 the graph shows the rate of world population

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

11 General Overview

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

Al-Shannagb 2012) From figure 11 the graph shows the rate of world population

and oil production whereas the rate of world population increases as the oil

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

111 Stage 3 Set up an experiment

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

other inconveniences such as environmental pollution and the emission of

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

11 General Overview

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

111 Stage 3 Set up an experiment

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

21 Introduction

In this chapter all relevant infonnation regarding renewable energy nonshy

renewable energy and the vital physical element in the blend of ethanol and gasoline

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

21 Introduction

In this chapter all relevant infonnation regarding renewable energy nonshy

renewable energy and the vital physical element in the blend of ethanol and gasoline

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

The world in the 21 st century presents many critical challenges The increase in

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

12 Background of Study

Since the late 1970s ethanol has been added to gasoline Since that time the

United States (US) fuel grade ethanol production capacity has grown over 12 billion

gallons per year and production volumes continue to increase Until the late 1980s

ethanols primary role in the fuel production was that of an octane enhancer and it

was viewed as an environmentally sound alternative to the use of lead in gasoline

With its 1125 blending octane ethanol continues to be one of the most economic

octane enhancers available to the refiner or fuel blender After that by 1980 s some

states began to use ethanol and other oxygenates in mandatory oxygenated fuel

programs to reduce the emissions of carbon monoxide (CO) The success of these

early oxygenated fuel programs led to a similar national program in the 1990 Clean

Air Act Amendments (Renewable Fuels Association 2011)

At the beginning of January 1995 the 1990 Clean Air Act Amendments also

required that certain ozone non-attainment areas sell reformulated Gasoline (RFQ)

Then recently in 2009 reformulated gasoline comprised 34 of all gasoline sold

The purpose of RFQ program is to reduce automobile emissions of volatile organic

compounds (VOCs) and Oxides of Nitrogen (NOx) which are ozone precursors The

program also designed to reduce toxic emissions (Renewable Fuels Association

2011)

Overall based on the RFQ requirements a great majority of the renewable fuel

will be produced with feedstocks other than com and row crops further improving

the already positive carbon footprint of com based ethanol The ethanol industry will

3

expand its production to meet RFQ requirements In fact in the late 20 I 0 over 88

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol

gasoline blends or commonly known as gasohol The investigation of vital physical

and combustion properties for a range of ethanol and gasoline will be gathering data

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

4

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

The world in the 21 st century presents many critical challenges The increase in

energy demand environmental concern of the global warming climate change and

increasing petroleum price in the worldwide has greatly increased the interests of the

application study of the use of alternative fuels (M AI-Hassana H Mujafeta and M

Al-Shannagb 2012) From figure 11 the graph shows the rate of world population

As global main energy resources fossil fuel which comprises of coal oil and

natural gas are 80 to 90 percent of total energy resources Meanwhile the remaining

10 to 20 percent of energy resources are supplied by nuclear and renewable energy

(Wohlgemuth and Missfeldt 2000 Asif and Muneer 2007) The prices of petroleum

products are generally on an increasing trend and consequently affecting the general

cost of living Besides that the most critical challenges are the environment As

world population increases and the standard of living improve there is a growing

concern that there will be a shortage of energy for homes vehicles which human

need the most Advances in technology have the allowed development of alternative

energy sources Alternative energy sources are renewable cleaner and more

dependable than traditional fuels The consumption of petroleum products also has

other inconveniences such as environmental pollution and the emission of

greenhouse gasses generally believed to be responsible for global warming (Tangka

JKelal 2011)

The general trend all over the world has now been to reduce the over dependence

on petroleum products so as to help reduce the effects of global warming Other

possible advantages of abandoning petroleum products is the fact that alternative

sources can be produced from renewable resources that are available almost

everywhere that there is life This avoids the employment of heavy infrastructure for

long distance transportation and distribution The need for alternative sources of

energy especially those that can be produced and utilized in enclave areas cannot be

over emphasized Amongst the various alternatives that are attracting attention today

is the use ofethanol as fuel for the motor vehicle engine (Tangka JK et aI 2011)

in Malaysian environment is useful to give some insight to estimate the usefulness of

Ethanol blends as compared to Gasoline or other equivalent fuels

13 Problem Statement

The dernand for energy is increasing day by day On the other hand fossil fuel

resources are exhaustible and expected to be depleted in the next 30 to 80 years

(Gevorkian 2006) Therefore corresponding to the decreasing amount of energy

resources a number of researchers and studies have been conducted to find

alternative energy of the future in which it sh~uld be more environmentally friendly

and sustainable Consequently the blends of ethanol and gasoline have high potential

and started since the late 1970s

Since that time US fuel grade ethanol production capacity has grown to over 12

billion gallons per year and production volumes continue to increase (Renewable

Fuels Association 2011) Regardless of the blend level the quality of the ethanol

added to gasoline is important This study will be focus on the physical and chemical

properties of the blends of ethanol and gasoline by measuring different ratio of fuels

14 Objective

The main objective of this project is to study to investigate vital physical and

combustion properties for a range of blends of ethanol and gasoline for instance

starting from E10 (10 Ethanol amp 90 Gasoline) and go up to E100

15 Research Methodology

In order to achieve the objectives as mentioned in Section 14 the study has

been divided into a few stages as follows

1 Stage 1 Literature review

Information on ethanol and gasoline are collected at this stage

Previous studies on the blends of ethanol and gasoline at different

range also reviewed in these stages The review focuses on vital

physical properties chemical properties and investigates previous

research done by using a different range of ethanol gasoline and also

different types of blends

11 Stage 2 The blend of gasoline and ethanol

Material for the experiment will be prepared In this study the

ethanol and gasoline will be prepared and then blend together

according to the ratio or range state below Besides that before set up

any experiment the Material Safety Data Sheet (MSDS) physical and

chemical properties for each material need to be prepared

111 Stage 3 Set up an experiment

After identifying the physical and chemical properties an experiment

should be set up by measuring all the criteria using different equipment in the

laboratory The procedure and criteria which are adopted from previous study

are then willing be interprets and analyses

iv Stage 4 Data collection

Data collection will be done experimentally or by using the previous

research collection

v Stage 6 results and discussions

The results are examined and discussed in detail The results are

depicted in the form of tables graphs comparisons and detail discussion on

the advantages and disadvantages are made

16 Expected outcome

Since the study is conducted to analyze vital physical and combustion properties

for a range of blends of Ethanol amp Gasoline The study is expected to provide

discussion on the physical and combustion properties which explained about the

6

characteristic for each property and its impact on the mixture of different range of the

fuel consumption

Besides that it is vital to find out the salient properties of both physical and

combustion natures for a range of blends for instance starting from E 10 (10

Ethanol amp 90 Gasoline) and go up to E80 and further The major physical

properties can be viscosity vapor pressure and the combustion properties can be

flash point energy content and much more Data in Malaysian environment is useful

to give some insight to estimate the usefulness of Ethanol blends as compared to

Gasoline or other equivalent fuels Furthermore it is important to take into

consideration about the Malaysia economic environmental and social impacts about

the blends of ethanol and gasoline mixture

17 Summary

This chapter generally discusses the importance of alternative energy in order to

confront global energy challenges which are the depletion of fossil fuel and their

impacts towards the environment Besides that the ethanol based fuel provides a

renewable fuel choice and the use of ethanol can reduce our dependence upon oil and

most importantly reduce greenhouse gas emIssions Therefore this study aims to

determine the vital physical and combustion properties for different range of ethanol

and gasoline a substitute for fossil fuel for power generation in Malaysia The

experiment will be conducted in order to analyze and determine the vital properties

in the mixture of ethanol and gasoline mixture

are discussed These include the infonnation extracted from previous studies which

had been conducted by other researchers The infonnation sources are mainly

derived from journals books electronic article (website) and etc

22 Energy demand in Malaysia

The world in the 21 st century presents many critical challenges One of the most

important challenges is the environment As population increases and the standard of

living improve there is a growing concern that there will be a shortage of energy to

heat our homes and power the vehicles on which so heavily depend Besides that

human also needs clean air clean water cleaner burning fuels biodegradable and

renewable materials In this modem era high technology has allowed the

development of alternative energy sources

8

Alternative energy sources are renewable cleaner and more dependable than

traditional fuels Power generation in Malaysia both used renewable energy and nonshy

renewable energy However non-renewable energy still dominated obviously

Renewable energy derives from hydropower wind and solar energy whereas nonshy

renewable energy is from oil natural gas and coal (Sopian et aI 2005) Malaysia oil

is estimated to last for another 19 years meanwhile the natural gas is estimated to last

for another 33 years (Selamat and Abidin 2010)

23 Fossil Fuel

Fossil fuels are non-renewable energy sources that formed more than 300

million years ago during the carboniferous period Today most of the energy that we

consume for our daily applications is produced from fossil fuels mainly derived

from petroleum natural gas and coal Oil was formed the remains animals and plants

in a marine environment When plants and animals died their bodies decomposed

and were buried under layers of earth sand and silt High temperature and high

pressure from these layers helped the remains tum into crude oils (Mohd Omar

Abdullah2012)

231 Petroleum

Basically the word petroleum means rock oil or oil from the earth

Petroleum is a complex mixture ofhydrocarbons which may be gas liquid or solid It

is better known as oil where depending on its own unique composition and the

pressure and temperature at which it is confined (Gatlin C 1960) Base designation

ofthe gasoline sold in the US already contained ethanol (Jim Jordan 2010)

Nowadays in Malaysia the automotive industry is expanding as well as the

increasing of fuels price in the market In order to overcome this problem oversees

development of alternative fuel use of alternative fuel become broad but in Malaysia

this area is still limited (Abdul Hadi 2010) This research focuses on ethanol
