摘要: 某石化公司催化裂化柴油(简称催化柴油)产量大、芳烃含量高、十六烷值低、加工难度大。为解决加氢裂化装置掺炼催化柴油时氢耗大、加工费用高等问题,将催化柴油改至焦化汽柴油加氢装置进行加工,并在不同催化柴油掺炼比例下进行工业试验,对比不同掺炼比例下的原料性质、主要操作参数、产品性质和物料平衡等数据。试验结果表明:焦化汽柴油加氢装置掺炼催化柴油后,柴油产品的密度和多环芳烃含量大幅上升,十六烷值大幅降低;反应平均温度提温幅度较大。在目前生产情况下,控制催化柴油掺炼比例不大于20%比较适宜。

Abstract: A large account of fluid catalytic cracking diesel(FCC diesel) with high aromatic content, low cetane number was produced in a petrochemical company. In order to solve the problems of high hydrogen consumption and high operating cost of FCC diesel processing in the hydrocracking unit, the FCC diesel is converted to the coking gasoline and diesel hydrogenation unit as an industrial test. The data of raw material properties, main operating parameters, product properties, material balance under different blending ratio were compared. The results show that the density and the content of polycyclic aromatic hydrocarbons are increased significantly, the cetane number is greatly reduced, and the average temperature of the reaction increases greatly. Under the present production conditions, it is suitable to control the feed ratio of FCC diesel no more than 20%.
