Abstract: Ethanol from lignocellulosic materials is the important developing orientation of bioenergy. In order to increase the digestibility of cellulose and hemicellulose, methods related with the removal of lignin from lignocellulose had been widely studied in recent years, which were focused on the pretreatment of biomass with acids, alkalis, oxides, organosolvs, ionic liquids and so on. Chemical technology for removing lignin at modest temperature and pressure will certainly accelerate the industrialization of cellulosic ethanol.
