Abstract: Recent research progress in chromium-based catalysts for propane dehydrogenation is reviewed. The dehydrogenation mechanism of propane to propylene，the active sites and catalyst deactivation with chromium-based catalysts are discussed. Influencing factors for catalyst activity，including preparation method，carrier，additives，carbon accumulation and production technology are also summarized，and the perspective for future research is also presented.
