Ethanol as an Alternative Energy Source Essays -- Biofuel Bio Fuel Ess

Biofuels fermentation alcohol an Alternative Energy SourceAbstractIn todays society, when someone wants to go to the movies, work, school, library, or mall, they drive to their destination. The average get along of gasoline consumed per family is about 146 gallons in the U.S. (Biofuels for Transportation, p1). Discoveries of huge petroleum deposits kept gasoline showy for decades and biofuels were forgotten (Leen, p1). However, with the recent oil prices, along with growing concern of world(prenominal) warming caused by deoxycytidine monophosphate dioxide emissions, biofuel regained popularity (Leen, p1). Ethanol, a renewable fuel do from plants was added to gasoline to increase octane and help the engines burn more efficiently and nice (West,p1).IntroductionEthanol or ethyl inebriant (EtOH) is an alternative zip fastener source which produces a fuel with higher octane rating and fewer emissions than unblended gas (West, p1). Some sources used to make ethanol are cole can es, maize, sorghum, fruit and vegetable waste, barley, wheat, potatoes, molasses, cotton, or any other plant that contains a large amount of scraping. But the leading U.S fuel crop is corn. corn whisky byproducts allow more fuel to be made from the same amount of corn by breaking down the starches in its cell walls (Benefits, p3). The enzyme Tran 2 increases production of alcohol from corn by 2% to 3% (Benefits, p3).thither are four steps toward making ethanol. First, the feedstock is ground for easier processing, then when the sugar is dissolved from the ground materials, the microbes feed on the sugar producing ethanol and carbon dioxide as byproducts (West, p2). Lastly, the ethanol is purified to achieve the correct concentration (West, p3). This grain alcohol is a colorless and flammable as well as drin... ...http// expedition tofor ever.org/ethanol.html.2.Martinez, Scott. Ethanol. 12 Sept 2005.
