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

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)
2
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

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

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

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

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

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
17 Summary

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

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

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

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

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

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
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

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

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)

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

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

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

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

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
