Ethanol Production

Bioethanol is basically

ethanol produced by

fermentation of glucose

and other sugars


3/13

Ethanol Production

Synthetic ethanol is

produced from ethene via

acid-catalyzed hydration

C2H4(g) + H2O(g) CH3CH2OH(l)

Pre-History

Ethanol has been used as

an ingredient in wines

dating back to Neolithic

times

Ever since, ethanol is being

used as additive in

beverages

Industrial Ethanol

1826

Engines were built to run on

ethanol and turpentine

1862 Massive tax on industrial

ethanol was done to raise

money for the Civil War

Gasoline became more

palatable as fuel

Ethanol as Fuel

1908 Ford Model T

Ran on either pure ethanol or

pure gasoline or a mixture of

both

Ethanol as Fuel

1940-1970

From the start of World War

II, demand for gasoline has

been exceptional

Gasoline prices dropped

dramatically and made it

more viable compared to fuel

ethanol

Around this time, bioethanol

from sugarcane is becomingrampant in Brazil

Ethanol as Fuel

1970 onwards

Oil embargos, and higher oilprices made countriesreconsider using ethanol for

fuel Solar Energy Research,

Development, andDemonstration Act of 1974 inenacted. Increased researchon substrate use was done.

1976 Blending ethanol with gasoline

became mandatory in Brazil(varying from 10% to 25%ethanol)

Ethanol as Fuel

1983

Genetic engineering of

fermenting microorganisms

were the subject of research

Late 1980s

Viability of cellulosic products

as substrates for ethanol

production has been

discovered

1992

Energy Policy Act mandated

car fleets to start buying

alternative fuel (E10 and E85)

Ethanol Production Today

US mainly operates under

E10 and gets raw materials

from corn

Brazil operates under E85

and gets raw materials

from sugarcane

2006 Biofuels Act

Republic Act 9367

develop and utilize

indigenous renewable and

sustainably-sourced clean

energy sources to reducedependence on imported oil;

mitigate toxic and greenhouse

gas (GHG) emissions;

increase rural employment

and income; and

ensure the availability of

alternative and renewableclean energy without any

detriment to the natural

ecosystem, biodiversity and

food reserves of the country.

Ethanol Production Today

On January 14,

2008, General

Motors announced a

partnership with Coskata,

Inc. The goal is to produce

cellulosic ethanol cheaply.

Advanced cellulosic

pretreatment methods

Pulsed-electric fieldpretreatment

Leyte Agricultural

Corporation opened the

first ethanol plant

dedicated to biofuels in the

Philippines in 2008.

Advanced enzymes and

microorganisms

Novel enzymes
