Abstract: Nearly 10 years after using semi-regenerative reforming catalysts PRT-C/PRT-D in 500 kt/a catalytic reforming unit of PetroChina Dushanzi Petrochemical Company, because of the increase of the carbon and iron content on the catalyst, the yield of C₅+ stabilized gasoline was decreased by 2—3 percentage points and the benefit of the unit was decreased. The simulation calculation of the processing effect of SR-1000 catalyst, which was newly developed by the SINOPEC Research Institute of Petroleum Processing, was carried out. The results show that the RON of C₅+ stabilized gasoline reaches 95 under the same conditions. Compared with PRT-C/PRT-D catalyst, the liquid yield, the pure hydrogen yield, recycle hydrogen purity of SR-1000 catalyst are increased by 3, 0.4 and 3.9 percentage points, respectively. The SR-1000 catalyst has obvious advantages in increasing the C₅+ gasoline and hydrogen. The economic profit of SR-1000 catalyst will be increased by 20.775 million yuan per year.
