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.
