Abstract: The main technologies of propane dehydrogenation at home and abroad, the reaction mechanism of propane dehydrogenation on Pt catalyst, the support and the promoter of Pt catalyst were reviewed. The problems of other catalysts for propane dehydrogenation and the advantages of chemical looping dehydrogenation technology were briefly introduced. Pt catalyst was optimized continuously to reduce cost. The main research direction in the future is to improve the stability of catalyst while reducing Pt content and develop non-Platinum and non-Chromium environment-friendly dehydrogenation catalyst.
