Cellulose is a renewable resource that is abundant on the earth.At present,fuel alcohol produced by pretreatment,saccharification and fermentation from cellulosic materials is more economical and environmentally friendly than gasoline or other traditional energy types.Therefore,cellulose alcohol is being developed into a new kind of renewable energy.The adoption of cellulose alcohol production technology makes the utilization of many cellulose materials from agriculture and forestry waste easy and comprehensive.It not only establishes a sustainable biological energy development model,eases the growing energy demand,but also benefits the bio-energy development,economic construction and environmental protection.This paper will present a review concerning the present technology stages of cellulose alcohol and the future development trends at home and abroad.
