FH-40C焦化汽油加氢精制催化剂的工业应用

COMMERCIAL APPLICATION OF FH-40C CATALYST FOR COKER GASOLINE HYDROFINING

中国石化安庆分公司0.2 Mt/a焦化汽油加氢精制装置采用中国石化抚顺石油化工研究院开发的FH-40C加氢精制催化剂,催化剂床层采用分级装填技术,器内湿法预硫化方法。根据生产实际需要,将原FH-98型催化剂更换为FH-40C型催化剂,以提升产品品质,并对新剂是否能够生产合格的催化重整预加氢原料进行了试验,同时对不同产品方案下的产品性质、装置能耗等进行了对比分析。近三年的运行结果表明,FH-40C催化剂具有优异的加氢脱硫和加氢脱氮活性,在工业应用过程中可灵活选择产品加工方案,焦化汽油经过不同深度加氢精制后,能稳定生产满足蒸汽裂解制乙烯原料或催化重整预加氢原料要求的产品。

FH-40C catalyst developed by Fushun Research Institute of Petroleum and Petrochemicals is used in a 0.2 Mt∕a coker gasoline hydrofining unit of SINOPEC Anqing Company. Hierarchical filling technology and wet presulfurization method were used. To enhance the quality of products,FH-98 cata-lyst was replaced by FH-40C catalyst. The performance of the new catalyst for producing qualified cata-lytic reforming feedstock was tested. The properties and energy consumption of different products were studied. The operation results over three years indicate that FH-40C has the excellent performance, such as high mechanical strength,high HDS and HDN activity and the flexibility to meet the processing scheme. The coker gasoline after hydrotreating with different depth can be stably converted into quali-fied feedstocks for steam cracking or catalytic reforming units.
