Abstract:

The target product bio-oil from biomass pyrolysis is difficult to be directly applied due to its high oxygen content and complex components. Deoxidization and upgrading of bio-oil can be realized by upgrading pyrolysis steam with suitable catalyst. Based on the previous studies, this paper firstly summarized the structural characteristics, catalytic principle and catalytic effect of metal oxides as well as zeolite catalysts in catalytic pyrolysis of biomass. Then, the construction principle and catalytic mode of micro-mesoporous composite together with metal oxide/ZSM-5 composite dual catalytic system were introduced in detail, as well as their influence on the product distribution of biomass catalytic pyrolysis, and the feasibility and practicability of dual catalytic system were also illustrated. At the same time, other factors including raw material characteristics, process parameters and operation working mode which affected biomass catalytic pyrolysis were summarized. Finally, in view of the existing problems in research and development of dual catalytic pyrolysis, the prospect of the comparative study of different dual catalytic modes, improvement of dual catalytic system to reduce production costs, and exploration of the multiple use values of dual catalyst were put forward.

Key words: biomass, pyrolysis, catalyst, dual catalysis, bio-oil, deoxidation

摘要:

生物质热解所得目标产物生物油因高含氧量、组分复杂等问题难以直接应用,通过使用适宜的催化剂升级热解蒸气可实现生物油的脱氧提质。本文基于前人研究,首先总结了生物质催化热解中金属氧化物和分子筛催化剂的结构特点、催化原理与催化效果。然后详细介绍了微介孔复合型、金属氧化物/ZSM-5复合型双级催化体系的构建原理、催化模式及其对于生物质催化热解产物分布规律产生的影响,并说明了双级催化体系的可行性与实用性;同时概述了影响生物质催化热解的其他因素,包括原料特性、工艺参数、操作模式等。最后针对目前双级催化热解研究与发展中存在的问题,对进行双级催化模式的比较研究、改进催化体系以降低生产成本、发掘双级催化剂的多种使用价值等方向提出了展望。
