摘要
芳烃是多用途的化学品,主要来源于石油和煤焦油等。以生物质和塑料为原料制取芳烃,可以缓解能源短缺和环境污染,实现生物质和塑料的资源化利用。催化剂能够增强共热解的协同效应,生物质与塑料进行催化共热解可以提高产物品质,改善热解产物分布,提高轻质芳烃的产率和选择性,抑制焦炭的生成。本文综述了生物质与塑料催化共热解制取芳烃的协同热解机理及影响因素,总结了不同种类催化剂的共热解研究进展,以期为生物质与塑料催化共热解定向调控制备芳烃工艺的改进和优化提供参考。
Aromatic hydrocarbons were multi-purpose chemicals,mainly derived from petroleum,coal tar and so on.The production of aromatics from biomass and plastics could alleviate energy shortage and environmental pollution,and realize the resource utilization of biomass and plastics.Catalysts could enhance the synergistic effect of co-pyrolysis,and catalytic co-pyrolysis of biomass and plastics could improve the product quality,the distribution of pyrolysis products and the yield and selectivity of light aromatics,and inhibit the generation of coke.In this paper,the synergistic pyrolysis mechanism and influencing factors of catalytic pyrolysis of biomass and plastics for the preparation of aromatics were reviewed,and the research progress of co-pyrolysis with different kinds of catalysts was summarized,with a view to providing a reference for the improvement and optimization of the process of preparing aromatics by directional modulation of biomass-plastics catalytic co-pyrolysis.
