可再生生物质资源的能源化利用能有效缓解能源短缺和环境恶化的双重压力。木质纤维素类生物质原料通过催化转化途径可以转化成为用途广泛的平台化合物,如呋喃类化合物、多元醇和有机酸及其酯类衍生物等。以这些平台化合物为原料,通过基元反应的转化可以制备高附加值的生物质基液体燃料。基于上述背景,本文概述了国内外木质纤维素通过不同催化转化途径制备各种新能源平台化合物的研究进展。目前木质纤维素制备新能源平台化合物的可行途径主要包括液体酸催化、固体酸催化、离子液体催化和多功能材料催化。在介绍这些催化途径的同时,重点讨论了所使用的催化剂,分析了仍然存在的问题和可能的解决措施,同时对今后该领域的研究前景进行了展望。
The energy utilization of renewable biomass resources can effectively alleviate the dual pressures of energy shortage and environmental degradation. Lignocellulosic biomass feedstocks can be transformed into a wide range of platform compounds such as furans, polyols and organic acids and their ester derivatives via catalytic conversion. Using these platform compounds as raw materials, high value-added biomass-based liquid fuels can be prepared by the conversion of elementary reactions. Based on the above background, this paper summarizes the research progress of lignocelluloses prepared by different catalytic conversion pathway at home and abroad for various new energy platform compounds. The current lignocellulose preparation of new energy platform compounds viable ways include liquid acid catalysis, solid acid catalysis, ionic liquid catalysis and multi-functional material catalysis. While introducing these catalytic approaches, the catalysts used are discussed in detail, the remaining problems and possible solutions are analyzed, and the future research prospects in this field are prospected.
