针对催化裂化条件对生物质热解焦油处理的影响，以秸秆热解产生的焦油为原料，在固定床焦油催化裂化反应试验台上研究了催化剂作用下焦油催化裂化的过程，并对催化剂粒径和质量等参数对焦油转化效果和催化裂化产物的影响进行了分析．结果表明：减小催化剂的粒径或者增加催化剂质量能促进燃气中高热值大分子气体转化为低热值的小分子轻质气体，从而有效促进焦油裂化，提高燃气产率，降低燃气热值．

According to the effects of catalytic cracking conditions on the treatment of biomass pyrolysis tar, the process of tar catalytic cracking under the action of catalyst was studied on the fixed-bed test rig by taking the tar from stalk pyrolysis as the raw material, so as to analyze the influence of catalyst particle size, mass and other parameters on the tar eonversion effect and the catalytic cracking product. Results show that the decrease in catalyst particle size or the increase in catalyst mass can facilitate the conversion of gases from large molecular size with high heating values into small molecular size with low heating values, so that the catalytic craeking of tar is promoted, the gas yield is improved and the gas heating value is reduced.
