Ethanol in Gasoline? • Improves exhaust emissions – mainly CO • A high-octane blending component • Displaces demand for petroleum • Increases demand for American corn • Decreases “global warming” from CO2 • Federal law limits low-level blends to 10%

Domenici-Barton Energy Policy Act of 2005 • New national policy requires that fuel ethanol increase to 7.5 billion gallons per year by 2012 • If blended as E10, it means that over 50% of the nation fuels will contain ethanol
Sources of Ethanol • Grain ethanol – made from corn, sorghum, barley, etc. – typical of US, Europe • Sugar ethanol – made from sugar cane – typical of Brazil • Cellulosic ethanol – made from plant fiber, wood, switchgrass, crop residues, etc
Gasolines are mixtures of many hydrocarbon molecules Ethanol C2H5OH MTBE C5H12O Butane C4H10 Oxygenates were required in gasolines in SMOG prone cities. MTBE is being banned, leaving ethanol as the popular choice Toluene C7H8 Octane C8H14
