木质纤维素类生物质是地球上最丰富的可再生资源,但纤维素、半纤维素、木质素三组分之间复杂的键合结构限制了其有效的转化利用.有机溶剂预处理是消除这种顽抗性的有效方法,其能有效拆解三组分、提高纤维素酶水解性能,并回收高纯木质素组分.随着对溶剂绿色和可持续性的要求,预处理有机溶剂正逐渐向生物基衍生溶剂方向发展,近期已有多种新型的生物基衍生溶剂预处理的报道.本文系统综述了基于Hansen溶度参数理论和CHEM21绿色溶剂指南的有机溶剂预处理体系设计,分别归类为均相体系、两相体系和多元相转化体系,归纳了生物基衍生预处理有机溶剂应用的研究进展,在此基础上探论了生物基衍生溶剂预处理面临的挑战和应用前景,以期为木质纤维素类生物质的有机溶剂预处理体系的设计和选择提供参考.
Research progress of lignocellulosic pretreatment based on bio-based derived organic solvents
Lignocellulosic biomass is the most abundant renewable resources on earth,but the complex bonding structure between the three components,cellulose,hemicelluloses and lignin,limits its effective conversion and utilization.Organic solvent pretreatment is an effective method to eliminate this resistance,which can effectively fractionate the three components,improve the hydrolysis performance of cellulase,and recover high purity lignin.With the requirement of green solvent and sustainability,the organic solvent pretreatment is gradually developing to use bio-based derived solvents.Recently,there have been a variety of new bio-based derived solvent pretreatment reports.This paper systematically reviewed the design of organic solvents pretreatment system based on Hansen solubility parameter theory and CHEM21 Green Solvent Guide.They were classified into homogeneous system,two-phase system and multiphase transformation system respectively,and the application of new bio-based derived pretreatment organic solvents was summarized.Finally,the research challenges and prospects of bio-based derived solvent pretreatment were discussed to provide reference for the design and selection of organic solvent pretreatment system for various lignocellulosic biomass.
