摘　　要：采用管式反应器研究了生物质炭作为焦油裂解催化剂的性能,选用白云石和石英砂作对比试验。通过对焦油转换率、裂解产物、裂解气气体组分和动力学参数的分析对比可知:在所选用的3种材料中,生物质炭作为催化剂的焦油转化率最高,裂解产物中气体所占比重最大,且可燃气体的组分较高,反应动力学参数最小。生物质炭的催化性能显著高于石英砂,稍好于白云石,是一种高效的焦油裂解催化剂。In a tubular reactor,the catalytic performance of biomass char on tar cracking were studied.Dolomite and quartz sand were also tested for the comparison.Through analysis and comparisons on conversion rate of tar,pyrolysis products,pyrolysis gas composition and kinetic parameters,it could be known that biomass char,as the catalyst of tar,could realize the highest conversion rate of tar,the largest proportion of gas in pyrolysis products,the more proportion of combustible gas in pyrolysis gases and the lowest kinetic parameters among three catalytic materials used in the study.The catalytic performance of biomass char is significantly superior than that of quartz sand and slightly better than that of dolomite,so it is an efficient catalyst for tar cracking.
