Abstract:

Pretreatment is the key technologies of the utilization of lignocellulose biomass for fuel ethanol. Advanced pretreatment technologies can significantly enhance the hydrolysis of cellulose, and then reduce the cost of fuel ethanol production .Starting with an introduction of the necessary of pretreatment of lignocellulosic biomass, the research progress of pretreatment technology such as physical methods, physical-chemistry methods, chemical methods and sand biologic methods were reviewed detailedly, the results of different pretreatment technologies were also analyzed. The future of development of lignoeellulosic biomass pretreatment technologies was also previewed.Key words: lignocellulose biomass; pretreatment; fuel ethanol
