摘　　要：通过实验方法研究在蒸汽环境下生物质炭对生物质热解焦油的催化重整特性。通过分析蒸汽加入量和加入方式的变化可知:在蒸汽条件下,生物质炭对焦油催化裂解效果显著,焦油转化率最高可达96.1%。通过对实验条件下焦油转化率、裂解产物、裂解气体积分数的分析可知,生物质炭和蒸汽可促进热解产物中的可凝结相转化为不可凝结的气体,且使气体组分体积分数发生变化。蒸汽以不同比例、不同位置输入裂解器中,有利于焦油的催化裂解和提高燃气的热值。In the article, the catalytic pyrolysis characteristics of biomass char on tar from biomass pyrolysis were studied by experiments. Through analyzing the change of tar conversion rate under conditions like S/C ratio and adding methods of steam, etc, conclusion can be drawn that biomass char has remarkable effects in tar catalytic cracking under steam conditions. The maximum tar conversion rate can be of 96. 1%. Throught the studies of changes of pyrolysis gas composition. Steam added by different methods is also in favour of the catalytic pyrolysis and the heat value of biomass gas.
