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 materials are analyzed.Moreover,the three latest fermentation technologies of produced ethanol by fermenting lignocellulosic materials are summarized,which are simultaneous saccharification and fermentation,immobilized cell fermentation and using high microorganism fermentation.We have achieved the important 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 ethanol by the continuation steam explosion technology.The industrialization test production line of producing 3000t / year cellulosic ethanol has come true in Henan Province.
