摘　　要：对氧化甲基吗啉(NMMO)预处理玉米秸秆的工艺条件进行了实验研究,考察了温度和处理时间对后续纤维素酶水解效果的影响。结果表明:在130℃条件下预处理1h,秸秆回收为71.5%,还原糖收率为0.51g/g。该条件既能保证较高的秸秆回收率,又能得到较好的水解糖化效果。In this article,the effects of two conditions of different pretreatment temperature and time of corn stover on enzymatic hydrolysis efficiency were investigated. The results showed that the yield of corn stover recovery and reducing sugar recovery were 71.5% and 0.51 g/g respectively under the NMMO pretreatment condition of temperature at 130 ℃ and time for 1 h. It was proved that in this study higher corn stover recovery and enzymatic hydrolysis efficiency were obtained at the same time.
