茂名石化劣质催化裂化柴油转化技术探讨

Study on conversion technology for low-quality FCC diesel

中国石油化工股份有限公司茂名分公司为了解决催化裂化柴油资源过剩问题,通过改造1号加氢裂化装置来处理催化裂化柴油,加上2号加氢裂化装置、蜡油加氢-催化裂化组合工艺、渣油加氢-催化裂化组合工艺配炼催化裂化柴油等一系列措施,找出劣质催化裂化柴油转化为汽油组分的有效途径。通过分析标定数据得知,改造后的1号加氢裂化装置使用针对处理催化裂化柴油的催化剂,可以有效将催化裂化柴油转化为汽油组分,汽油转化率高达51.61%,每年可创造效益9 458万元,仅仅靠后3种方法达不到如此的效果。

To find solution to the problem of excessive catalytic diesel resources, SINOPEC Maoming Company has adopted a number of measures such as revamping No. 1 hydrocracking unit to treat FCC diesel, application of integration of No. 2 hydrocracking, heavy gas oil hydrotreating and FCC processes and integrat- ed residue oil hydrotreating and FCC process, etc to find effective means to convert low-quality FCC diesel to gasoline component. The analysis of performance test data showed that the No. 1 hydrocracking unit can effectively convert the FCC diesel into gasoline component with appropriate catalysts. The gasoline conversion is as high as 51. 61%, and the annual economic benefits is 94.58 million Yuan （ RMB ）, which can not be achieved by other 3 processes.
