PRODUCTION OF ETHANOL FROM WHEY AND MOLASSES
Keywords:Ethanol , carbon dioxide, fermentation
Fuel ethanol has become a very important agricultural product over the past two decades . In 2005, more than 13% of US Corn production went towards making this fuel additive which lessens U.S. dependence on forign oil imports , is cleaner for the environment , and has substantial impact of the rural economy and agriculture production .all ethanol production is based upon the activity of yeast an important microorganism to humans. Through a process called fermentation . yeast eat simple sugars and produce caron dioxide (co2) and ethanol is a waste product. For each pound of simple sugars , yeast can produce approximately ½ pound (0.15 gallons) of r etanol and an equivalent amount of carbon dioxide. All cars and trucks on the road today can use gasoline/ethanol blends of up to 10% ethanol (90% gasoline ). Also called”e10” blends of up to 85% ethanol, also known as “E85,” can be used as transportation fuel by cars and trucks with slight modifications (approximately $ 100 per vehicle.) These flexible fuel vehicles can use either gasoline or ethanol blends, including E85.
