摘要
木质纤维生物质结构组成复杂,导致原料利用率低、生产成本高.对生物质进行组分分离,是实现其全组分高效利用的前提.根据化学法分离生物质组分的特点,可将其归为3类:纤维素优先、木质素优先和半纤维素优先.本文介绍了3种优先策略的特点及其所包含的主要方法,重点综述了这些方法的最新进展,并对各方法的优劣势及组分分离效果进行了分析.最后,对未来生物质高效分离技术优化及生物精炼的研究重点提出了展望.
Abstract
The complex structural composition of biomass resulted in low raw material utilization and high production costs.The separation of biomass fractionation was the premise to achieve efficient utilization of all components.Based on the characteristics of biomass component separation using chemical methods,it could be categorized into three categories:cellulose-first,lignin-first,and hemicellulose-first.The characteristics of different component prioritization strategies and the main methods included in each strategy were introduced in this paper.The latest advancements in various methods under different strategies were emphatically reviewed.Moreover,the strengths and weaknesses of each method,as well as their effects on the separation of different components,were analyzed.Additionally,the research focus on the future optimization of efficient biomass fractionation technologies and how to drive the development of bio-refining was prospected.
