摘要
以纤维素为原料生产燃料乙醇由于其原料来源广泛及环保效益良好而被认为是最有前景的生产燃料乙醇的方法之一。以纤维素为原料生产乙醇主要包括水解和发酵两个转化过程。本文介绍了纤维素生产燃料乙醇的原理及工艺过程,同时讨论了各工艺过程需要解决的关键技术问题,分析了过程的经济性,最后介绍了国内外的应用现状,展望了纤维素生产燃料乙醇的产业化前景。
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.
