摘　　要：溶剂液化是生物质原料高效、综合利用的一种有效途径。相比单一溶剂水,混合溶剂体系可以降低反应的温度和压力、提高生物质的转化率、降低生物油中的氧含量以及提高目标产物的产率。本文综述了近年来常见的水混合溶剂体系,包括醇-水共溶剂、极性非质子溶剂-水体系和离子液体-水体系,在木质纤维生物质降解过程中的作用,特别是乙醇-水共溶剂、四氢呋喃(THF)-水共溶剂和γ-戊内酯(GVL)-水共溶剂在生物质液化中的应用特点,并给出了这些溶剂在生物质液化领域的不足及建议。最后,基于溶剂本身的经济价值、回收和安全性能的考量,指出低成本环保可持续液化溶剂的开发将是未来重点发展的方向。Solvent liquefaction was an effective process which could utilize biomass raw materials efficiently and comprehensively.Compared with water as a single solvent,the mixed solvent system could reduce the reaction temperature and pressure,improve the conversion of biomass,reduce the oxygen content in bio-oil,and increase the yield of the target product.This paper reviewed the common water mixed solvent systems in recent years,including the role of alcohol-water cosolvent,polar aprotic solvent-water system and ionic liquid-water system in the degradation process of lignocellulosic biomass,especially the application characteristics of ethanol-water cosolvent,tetrahydrofuran(THF)-water cosolvent andγ-valerolactone(GVL)-water cosolvent in biomass liquefaction.This paper also gave the shortage and suggestions of these solvents in biomass liquefaction field.Finally,based on the consideration of the economic value,recovery and safety performance of the solvent itself,it is pointed out that the development of low-cost,environment-friendly and sustainable liquefying solvents would be the key development direction in the future.
