英文摘要：

Steam explosion is one of the most common physico-chemical pretreating methods,this method is the short-time processing with low-energy input and negligible environmental impact.The research approach,the technological routing and the existing problems of steam explosion were introduced.All the factors such as pretreating intensity,pre-impregnation condition,inhibitor pro-duction and detoxication,as well as molecular structure change have the significant impact on ma-terial recovery,enzymatic hydrolysis rate and sugar yield,these experimental index will further af-fect the ethanol yield.Furthermore,the future development trend is proposed that is to optimize the process conditions in steam explosion pretreatment and subsequent detoxication.
