Progress in the New Fermentation Technologies of Fuel Ethanol

Abstract

Fuel ethanol converted from biomass is a reliable substitute for fossil fuels, and lays people’s hope on the sustainable development in the fields of energy and climate. The limitation in source of raw materials and production cost are bottlenecks which restrain the wide use of fuel ethanol. This article makes an overview of the current research progress in the new technologies from the directions in the exploiting of raw materials and energy saving and polluted water emission reduction in the production process of fuel ethanol, and analyzes the potential application prospects and advantages of various new technologies.
