Ethanol

Ethanol is the dominant biocomponent in the gasoline market. Edible ethanol is produced by fermentation of sugar-containing feedstock. Production of fuel ethanol from cellulosic feedstock is under commercialization phase. Industrial ethanol can be produced from petrochemical ethylene by the acid-catalyzed hydration, but this cannot be used to meet bioenergy obligations. Ethanol is a monomolecular compound with narrow boiling point, whereas gasoline consists of hundreds of different hydrocarbon molecules. Ethanol is aromatic-, olefin- and sulfur-free compound. Oxygen content of ethanol is 35%.
