摘　　要：基于生物质焦油的组成特性、危害及其处理方法,简单介绍了生物质焦油催化裂解脱除的机理及近年来的研究进展,重点阐述了生物质炭对焦油的催化转化机理(主要涉及裂解、重整和缩合3种反应)、生物质炭对焦油的吸附和重整作用,以及在催化转化过程中,生物质炭的催化性能受原料、裂解温度、加热速率和停留时间等因素的影响。通过分析生物质炭改性后的性能变化,发现生物质炭中添加金属助剂或经结构改性后具有高效催化裂解焦油的潜力,为进一步研发低成本复合型催化剂提供了方向。Based on the composition characteristics,hazards and treatment methods of biomass tar,the mechanism of catalytic cracking of biomass tar and the research progress in recent years are briefly introduced,and the catalytic conversion mechanism of biomass charcoal(mainly involving cracking,The three reactions of reforming and condensation),the adsorption and reforming of biomass charcoal,and the catalytic conversion process,the catalytic performance of biomass charcoal is affected by factors such as raw materials,cracking temperature,heating rate and residence time.By analyzing the performance changes of biomass charcoal after modification,it is found that the addition of metal promoters or structural modification of biomass charcoal has the potential for high-efficiency catalytic cracking of tar,which provides a direction for further research and development of low-cost composite catalysts.
