摘要
木质素的降解对生物质资源的有效使用具有重要意义。木质素储量巨大,但其分子量大且性质稳定,限制了其高效利用。目前酸催化降解木质素是较为普遍且有前景的催化方法,尤其是杂多酸催化降解,可将木质素转化为生物油。介绍了木质素的3种结构单元及木质素单体间的连接方式,从催化剂等方面阐述了国内外木质素酸催化降解的最新研究进展,并探讨了反应机理。在此基础上,针对降解过程中遇到的问题,提出了未来的研究方向。
The degradation of lignin is of great significance for the effective use of biomass resources.Lignin has huge reserves,but its high molecular weight and stable properties limit its efficient utilization.At present,acid catalyzed degradation of lignin is a common and promising catalytic method,especially heteropoly acid catalyzed degradation,which can convert lignin into bio oil.The three structural units of lignin and the connection modes between lignin monomers were introduced.The latest research progress of acid catalyzed degradation of lignin at home and abroad was described from the aspects of catalysts,and the reaction mechanism was discussed.On this basis,aiming at the problems encountered in the degradation process,the future research direction is put forward.
