摘要:

木质素是一种重要的生物质可再生资源,其降解后得到的酚类物质加氢后可得大量高附加值化学品,在环境治理和原料利用方面都有着十分重要的影响。本文综述了近年来国内外木质素酚类加氢反应催化剂的研究进展,总结了液相酚类催化加氢催化剂的种类、反应机理及结构敏感性因素对酚类催化加氢反应活性的影响,阐述了催化剂颗粒尺寸对液相酚类加氢反应活性影响,并以木质素液相酚类加氢反应催化剂的活性金属和载体为体系,对现有的结构敏感性反应中催化剂存在的形貌效应、晶相效应进行了讨论。提出未来可通过控制催化剂形貌和晶相来研究催化剂形态与催化活性之间的构效关系,为今后设计高活性木质素液相酚类加氢催化剂提供借鉴和参考。

Abstract:

Lignin is an important renewable biomass resource. A large number of high value-added chemicals can be obtained from phenolic substances after degradation and hydrogenation, which have a very important influence on environmental treatment and raw material utilization. This paper reviewed the research progress of lignin phenol hydrogenation catalysts in recent years. The effects of the type, reaction mechanism and structural sensitivity of the liquid phenolic catalytic hydrogenation catalyst on the catalytic hydrogenation activity of phenols were summarized, and the effect of catalyst particle size on the activity of liquid phenol hydrogenation reaction was described. The morphological effect and crystal phase effect of the catalyst in the existing structural sensitivity reaction were discussed by using the active metal and carrier of the lignin liquid phenol hydrogenation catalyst as the system. It was proposed that the structure-activity relationship between catalyst morphology and catalytic activity can be studied by controlling the morphology and crystal phase of the catalyst to provide information and reference for the design of high-activity lignin liquid phenol hydrogenation catalyst in the future.

Key words: catalyst, biomass, hydrogenation, nanostructure, morphology
