Abstract: The first commercial application of PS-VII catalyst developed by Research Institute of Petroleum Processing was carried out in the 1.39Mt/a continuous catalyst regeneration (CCR) reforming unit of Yangzi Petrochemical Company. The results of performance test and commercial run showed that PS-VII catalyst exhibited high attrition resistant and good hydrothermal stability. As compared with the original imported catalyst, using PS-VII catalyst even with a poorer feedstock, the yields of C6+, hydrogen and aromatics increased 3.32, 0.61 and 1.53 percentage points, respectively; at the same time the coke deposition rate reduced 27.32%. Thus, the problem of insufficient regeneration capacity was solved and the unit could be run under high load for a long period.
