摘要:

生物质是化石能源的潜在替代资源,木质素是自然界第二大生物质资源,将木质素催化转化为高附加值化学品对国家“双碳”战略实施具有重要的意义。催化剂和溶剂是影响木质素催化转化反应过程的关键因素,本文概述了催化氢解木质素过程中常用的金属、分子筛和金属氧化物催化剂的作用机理以及性能调控规律,并对不同溶剂分散和供氢作用进行了对比分析,通过溶剂效应原位表征、溶剂反应路径模拟,探究催化剂结构和性能间的构效关系,明晰催化剂与溶剂对木质素催化氢解的协同作用机制,为木质素的资源化和高值化利用提供了理论基础。

Abstract:

Biomass is a potential alternative resource for fossil fuels, and lignin is the second largest abundant reserves of biomass resource in nature. The catalytic conversion of lignin into high value-added chemicals is of great significance for the implementation of the national dual carbon strategy. Catalysts and solvents are key factors affecting the catalytic conversion of lignin. This article outlines the mechanisms and performance control laws of commonly used metals, molecular sieves, and metal oxide catalysts in the process of catalytic hydrogenation of lignin. Different solvent dispersion and hydrogen supply are compared and analyzed. Through in-situ characterization of solvent effects and simulation of solvent reaction pathways, the structure-activity relationship between catalyst structure and performance is explored, clarifying the synergistic mechanism of catalysts and solvents on lignin catalytic hydrogenation, providing a theoretical basis for the resource utilization and high-value utilization of lignin.

Key words: lignin, hydrodeoxygenation, catalysts, solvent, high-valued utilization
