摘　　要：纤维乙醇是第二代生物燃料,它对于国家粮食和能源安全具有重要意义,但是纤维乙醇在工业化生产过程中面临诸多问题。为提高纤维乙醇工业化的生产效率,现就生产纤维乙醇的分批酶解方式进行改进,设计了连续酶解生产纤维乙醇的工艺,并进行中试试验,探索其工艺参数,并验证其可行性,为工业化连续生产纤维乙醇做好准备。试验结果表明:连续酶解工艺纤维酶解过程共需要47.8 h,糖度可达到12.7%;酒精度可达到6.0%(vol),已满足工业化生产酒精度的要求。Cellulosic ethanol is a second generation bio fuel,which has great significance for the national food and energy security,but it faces many problems in the process of the industrial production of cellulosic ethanol. In order to improve productivity of industrialized continuous production of cellulosic ethanol,the continuous digestion method of cellulosic ethanol production was designed,and was conducted a pilot test to verify its feasibility. The results showed that sugar degree reached 12. 7% and alcohol degree reached 6. 0%（ vol） in the process of continuous digestion after 47. 8 h.
