摘　　要：催化裂化油浆经胺类溶剂萃取分离后,对所得的抽余油及其掺炼油进行催化裂解,分别考察了反应温度、剂油比、空速对产品分布、目标产物产率和选择性的影响,确定最佳工艺操作条件。结果表明,抽余油具有良好的DCC性能,其最佳反应条件为剂油比9.3,反应温度570℃,空速14.5 h-1,在此条件下的产品分布为,重柴油7.69%,轻柴油8.24%,汽油24.43%,液化气34.12%,干气15.17%,焦炭10.35%。抽余油掺炼重油的比例应小于20%。After the extraction separation of FCC slurry by amine, the deep catalytic cracking of raffinate oil from slurry oil and blending crude oil is performed. The influences of reaction temperature, ratio of solvent to oil and space velocity on the product distribution, the yield and selectivity of the targeted product are investigated. The obtained raffinate oil can achieve good DCC performance under the following conditions：9. 3 of catalyst to oil,570℃ of reaction temperature and 14. 5 h -1 of space velocity. Under these conditions, the contents of heavy diesel oil, light diesel oil, gasoline, liquefied gas, dry gas and coke are 17.69 %, 8.24%, 24.43 %, 34. 12%, 15.17 % and 10. 35 %, respectively. The ratio of raffinate oil to crude oil should be less than 20%.
