| Abstract | As petroleum prices continue to escalate and the pressure increases to gain energy independence from foreign suppliers, ethanol is receiving renewed attention as an alternative to petroleum derivative fuels. Fermentation ethanol is one of the most promising non petroleum fuels that can be produced in the near term and is the first non petroleum fuel to attain widespread use into eh United States through the sale of gasohol, a blend of 10 percent anhydrous ethanol and 90 percent gasoline. Fermentation anhydrous ethanol is manufactured by converting biomass to fermentable sugars, fermenting the sugars to a low concentration ethanol solution, then distilling and dehydrating the ethanol. |
