摘　　要：生物质催化热解获得生物油等高质产品是最有前途替代传统化石能源的方法之一,但在热解过程中存在着严重的催化剂失活问题,其中积炭是导致催化剂失活的最主要因素。本文对近年来生物质催化热解领域的催化剂积炭问题进行综述,重点介绍催化剂积炭失活原因及表征方法、积炭的影响因素分析(催化剂结构、催化剂酸性与反应温度)、抑制催化剂积炭的方法(催化剂改性、高压反应条件等)以及积炭催化剂再生方法(氧化灼烧再生、臭氧低温再生、非热等离子体再生等),并介绍了近年来新兴的微波催化热解技术对催化剂积炭的抑制和消除作用,然后针对该领域目前所面临的困难和发展方向进行展望,以期为生物质催化热解过程中催化剂积炭问题研究提供理论基础。Biomass catalytic pyrolysis to obtain high-value products such as bio-oil is one of the most promising methods to replace traditional fossil energy.However,there is a serious catalyst deactivation problem in the pyrolysis process,among which carbon deposition is the most important factor leading to catalyst deactivation.This paper reviews the catalyst carbon deposition in the field of biomass catalytic pyrolysis in recent years,focusing on the causes and characterization methods of catalyst carbon deposition deactivation,the analysis of the influencing factors of carbon deposition(catalyst structure,catalyst acidity and reaction temperature),the inhibition of catalyst carbon deposition(catalyst modification,high pressure reaction conditions,etc.)and coke catalyst regeneration methods(oxidative burning regeneration,ozone low-temperature regeneration,non-thermal plasma regeneration,etc.).The new microwave catalytic pyrolysis technology to inhibit and eliminate catalyst carbon deposition is intruduced.The current difficulties and development directions in this field are prospected,in order to provide a theoretical basis for the study of catalyst carbon deposits in the process of biomass catalytic pyrolysis.
