摘　　要：以硅铝比20∶1的HZSM-5分子筛作为催化剂、小桐子油为原料,于实验室的小型模拟固定床装置中进行催化裂化试验。通过考察不同裂化温度、质量空速、催化剂用量对催化裂化反应的影响优化反应条件。结果表明:小桐子油催化裂化制备燃料油的最佳工艺参数为裂化温度500℃、质量空速2.72 h^(-1)、催化剂用量33.3%(以原料质量计),此时转化率最高,为29.60%,脱氧率为53.77%,产物多为芳烃类化合物。Using HZSM - 5 molecular sieve withoil as raw material, and the mini fixed bed inratio of silica to alumina 20：1 as catalyst ,Jatropha curcaslaboratory as reactor, the catalytic pyrolysis reaction wasconducted. The effects of pyrolysis temperature, weight hourly space velocity and dosage of catalyst oncatalytic pyrolysis reaction were investigated to optimize the pyrolysis conditions. The results showed thatthe optimal pyrolysis conditions were obtained as follows： pyrolysis temperature 500 ℃, weight hourlyspace velocity 2.72 h - 1 and dosage of catalyst 33.3 % （ based on mass of raw material）. Under these con-ditions, the conversion rate of Jatropha curcas oil was the highest,reaching 29.60%, and the deoxygen-ation rate was 53.77%. The product was mainly composed of aromatics.
