Abstract: Progresses in propane catalytic dehydrogenation and propane oxidation dehydrogenation of Cr-based catalysts were reviewed. The active sites of catalyst,dehydrogenation mechanism and influence factors for the reaction in two processes were introduced. The reasons of catalyst deactivation were analyzed and the influence of regeneration on catalyst performance was discussed. The development of new type catalysts with lower Cr content, higher selectivity and better resistance to coke deposit is the current focus. While the Cr-based catalyst for propane oxidation dehydrogenation with improved propane conversion rate and higher propene yield is the main direction in future.

Key words: propane dehydrogenation, Cr-based catalyst, deactivation, regeneration
