Abstract:

Lignocellulosic biomass is considered as one of the most promising feedstock for fuel-ethanol production due to its renewable and environment–friendly nature. This review summarizes the technological processes of fuel-ethanol production from lignocellulosic biomass，including concentrated acid hydrolysis，dilute acid hydrolysis and enzyme hydrolysis，and their technical characteristics are analysized. The acid pretreatment - enzymatic hydrolysis process is considered to be the focus of research and development in the coming years.

摘要：

以木质纤维素生产燃料乙醇具有原料可再生性和环境友好的优点而备受重视。本文介绍了国内外木质纤维素制取燃料乙醇中的水解工艺过程，包括浓酸水解、稀酸水解和酶水解工艺，分析了各工艺的技术特点，同时指出稀酸预处理-酶水解工艺将成为近几年国内外研究和开发的重点。
