化学处理方法对木质纤维素降解效率的影响评述

摘要

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.%纤维素乙醇是生物质能源的重要发展方向。为了提高纤维素和半纤维素的降解效率,以酸化、碱化、氧化、有机溶剂、离子液处理为代表的木质素去除方法成为近年来的研究热点。常温常压条件下有效去除木质素的化学方法,必将加速纤维素乙醇的产业化进程。
