Abstract: PS-VI catalyst developed by Research Institute of Petroleum Processing was used in the 800 kt/a continuous catalyst regeneration reforming unit of Zhenhai Refining and Chemical Company. The commercial running results showed that PS-VI catalyst exhibited high resistant against attrition, good hydrothermal stability and chloride retention ability. As compared with the base catalyst, using PS-VI catalyst at the initial stage the yields of aromatics, reformate and hydrogen increased 6.46, 1.32 and 0.35 percentage points, respectively; the coke rate reduced more than 26%. As compared with the catalyst at the initial stage, at the end stage (after running 1 918 days) the catalyst activity slightly decreased due to the increase of impurities, the reformate yield dropped 1.28 percentage points.
