Abstract:

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 catalyst was replaced by FH-40C catalyst. The performance of the new catalyst for producing qualified catalytic 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 qualified feedstocks for steam cracking or catalytic reforming units.
