Description:
Bioethanol is the most important liquid fuel made in the U.S. from domestically produced renewable resources. Traditional production of bioethanol involves batch fermation of biomass followed by ethanol recovery from the fermentation broths using distillation. The distillation step of this energy-intensive production process accounts for about 40% of the total energy needed for corn-to-ethanol conversion. A more energy effecient recovery process wll reduce the cost of ethanol production, reducin its dependence on federal subsidy. In addition, it will permit the bioethanol production from a wider variety of biomass.
