Abstract:

Propylene is an important industrial raw material mainly used in the production of polypropylene,acrylonitrile,isopropyl alcohol,acetone and propylene oxide.With the increasing demand for propylene,the technology of propane dehydrogenation has been widely used in the industrial production of propylene.Although platinum-based and chromium-based catalysts have high activity in propane dehydrogenation,they are also prone to poisoning and deactivation.Metal oxides have attracted widespread attention as alternative non-precious metal catalysts.Firstly,the reaction pathway and deactivation mechanism of propane dehydrogenation catalyzed by metal oxides were introduced.It was pointed out that enhancing the C—H activation ability,alleviating the reconstruction and reduction of active components were the key to improving the propane dehydrogenation performance of metal oxide catalysts.Then,several representative metal oxide catalysts were reviewed in detail,the mechanism of action and active species of various catalysts were summarized,and the existing problems of corresponding catalysts were analyzed and discussed.Finally,key research directions for future propane dehydrogenation catalysts were proposed,which was expected to provide new ideas for the direct production of chemicals through the activation of low-carbon alkanes.

Key words: propane dehydrogenation, metal oxides, active site, reaction pathway, stability, non-precious metal catalysts
