Abstract: The present development status of research on low carban alkane dehydrogenation was reviewed.The low carbon alkane dehydrogenation methods，including anaerobic dehydrogenation and aerobic dehydrogenation were introduced.The main drawbacks of Pt-based catalysts for low carbon alkane dehydrogenation were poor stability and low selectively.The influences of active component，supporters，and different additives on the performances of Pt-Sn catalyst were introduced.Series chromium catalysts and technologies of low carban alkane dehydrogenation in aboard were described briefly.Finally，the trend of low carban alkane dehydrogenation catalyst in the future was proposed.

Key words: Pt-Sn catalyst, additive, process
