Abstract:The dehydrogenation of light paraffins was widely applied in the large-scale production of olefins. The characteristics of the dehydrogenation technologies were reviewed. Among them,the Oleflex process and Catofin process were illustrated due to their high market share. Two catalyst systems for the dehydrogenation processes were discussed. The difference between the propane dehydrogenation and the isobutane dehydrogenation were summarized. It was predicted that,the favourable synergy between the catalyst design and the reactor engineering would be the development trend of the light paraffin dehydrogenation in future. The most urgent task was the investigation and production of domestic dehydrogenation catalysts.

Key words: dehydrogenation of light paraffins   olefins   dehydrogenation process   dehydrogenation catalysts
