木质纤维转化制燃料乙醇的研究进展

综述了蒸汽爆破、微波辅助等木质纤维原料的预处理方法,分析了木质纤维原料的酸水解与酶水解,总结了木质纤维原料发酵制取乙醇的三种最新发酵工艺,即同步糖化发酵、固定化细胞发酵、利用高效微生物发酵。我国在木质纤维原料生产燃料乙醇的技术应用已取得了重要进展,首次采用连续汽爆技术建设成500t/年纤维素乙醇产业化试验装置,河南建成首条年产3000t的纤维乙醇产业化试验生产线。

Research Advances in Production of Fuel Ethanol From Lignocellulosic

This paper summarized the pretreatment methods of lignocellulosic materials in the paper, such as steam explosion, microwave- assisted. Acid hydrolysis and enzyme hydrolysis of lignocellulosic mate- rials are analyzed. Moreover, the three latest fermentation technologies of produced ethanol by fermen- ting lignocellulosic materials are summarized, which are simultaneous saccharification and fermentation, immobilized cell fermentation and using high microorganism fermentation. We have achieved the impor- tant progress in the technology application of producing fuel ethanol by lignocellulosic materials in our country. It was the first time to build the industrialization tester of producing 500 t/year cellulosic etha- nol by the continuation steam explosion technology. The industrialization test production line of produ- cing 3000t/year cellulosic ethanol has come true in Henan Province.
