Industrial Application of FH-40A Catalyst in Jet Fuel Hydrogenation Unit
The physical parameters and hydrogenation reaction principle of FH-40A hydrogenation catalyst were introduced,and its application in jet fuel hydrogenation unit was analyzed and summarized.The FH-40A catalyst was first used in jet fuel hydrogenation unit of Sinopec Shijiazhuang Refining and Chemical Company in 2021.The calibration and operation results of the unit showed that when the FH40A catalyst was used to treat the existing kerosene feedstock,and the inlet pressure of the reactor was 2.293～2.298 MPa,the inlet temperature of the reactor was 256.58～256.84℃,the catalyst had excellent mercaptan removal performance.The refined jet fuel after processing can meet the standard requirements of 3#jet fuel.The unit can produce-35#diesel which can meet the national VI standard in the initial stage of catalyst operation.With the unit running,the activity of FH-40A catalyst slightly decreased,and the pressure drop of catalyst bed changed more smoothly,the catalyst had good activity and stability,which was beneficial to the long-term operation of industrial plant.
