Method used

The hydroprocessing catalyst used in the hydroprocessing reaction of the present invention preferably comprises two or more than two types of catalysts, and the reaction raw materials are first contacted with the larger hydrogenation protection agent etc. in aperture and pore volume, and then with the main Hydrotreating catalyst contact. The main hydrotreating catalyst accounts for 80%-100% of the total catalyst volume, preferably 90%-95%. Various catalysts can be selected from commercial catalysts, and can also be prepared according to schemes in the art. Commercial hydrogenation catalysts with larger pore diameter and pore volume, such as FZC-100, FZC-102B, FZC-103 and other hydrogenation catalysts developed and produced by Fushun Petrochemical Research Institute. The main hydrotreating catalyst can be a common hydrotreating catalyst in the field, such as FH-5, FH-5A, FH-98, FH-40A, FH-40B, FH-40C and other catalysts developed and produced by Fushun Petrochemical Research Institute , can also be other similar catalysts, preferably FH-98 catalyst and FH-40C catalyst. The main hydrotreating catalyst may also include a deep hydrotreating catalyst with high metal content, such as the FH-FS hydrotreating catalyst developed and produced by Fushun Petrochemical Research Ins...

Abstract

The invention discloses a mixed hydrogenation technique of coking kerosene and virgin kerosene; deep hydrogenation refining is carried out on a hydrogenation device for adjusting the operation conditions of a fractionating tower; a proper cutting point is adopted for obtaining qualified hydrogenated naphtha and hydrogenated kerosene. In the invention, the coking kerosene and the virgin kerosene are mixed for carrying out deep hydrogenation refining and flexibly adjusting the price of oil products as well as the yields of the kerosene and the virgin kerosene, thereby remarkably improving the economic benefits of oil refinery enterprises.
