Abstract: In order to gradually achieve the maintenance goal of one in five years, the novel type of high activity and stability FHUDS-10 catalyst is used in the 3.0 MM TPY diesel hydrogenation unit of SINOPEC Jinling Company. From the perspective of overall process, the feed rate of the unit and the inlet temperature of the reactor are optimized to meet the market demand for the properties and yield of refined diesel. After 6 months of operation, the unit is calibrated. The calibration results show that the processing ratio of FCC diesel is 17.60%, the final distillation point is 366 ℃, and the mass fraction of nitrogen is 158 μg/g, sulfur mass fraction 1.10%; the density of refined diesel is 0.845 8 g/cm³ and the mass fraction of sulfur is 5.8 μg/g, nitrogen mass fraction 0.5 μg/g, which fully meets the quality standard of Guo Ⅵ diesel. The unit has operated for more than one year, by optimizing process conditions, the inlet temperature can still reduce back to the low level, which fully reflects the good activity and stability of FHUDS-10 catalyst.
