英文摘要：

Lignocellulosic biomass is considered one of the most promising feedstock for producing fuel ethanol due to its global availability and environmental benefits. The conversion process of fuel ethanol utilizing lignocellulosic biomass involves hydrolysis and fermentation. In this paper, the mechanisms of conversion of lignocellulosic biomass to ethanol are introduced. The technological progress of fuel ethanol production from lignocellulosic biomass is extensively reviewed and the key problems to be solved of different processes are also discussed. Meanwhile, the technological economics analyses of the process are provided. Finally, the status of practical application and the prospect of industrial application of fuel ethanol producing from lignocellulosic biomass are presented.
