Abstract: The characteristics of catalyst regeneration technology of countercurrent continuous catalytic reforming were introduced from the aspects of catalyst flow direction，loading ratio，catalyst circulation and process safety of regenerative system. And at the same time，the possible or existing problems in the catalyst regeneration process were discussed. The corresponding countermeasures and practical solutions were suggested. The PS-VI catalyst developed by SINOPEC Research Institute of Petroleum Process showed high activity，stability，chlorine holding ability as well as wear resistance in the industrial application.
