Propane catalytic dehydrogenation to propylene was investigated over novel platinum-based catalysts, and the BET, H-2-chemisorption, H-2-TPR, H-2-TPD, C3H6-TPD and O-2-pulse techniques were used for catalyst characterization in this paper. The results showed that the addition of Zn and Ce promoters into Pt-based catalyst could remarkably improve the performances of dehydrogenation. Highly propylene selectivity, about 99%, was obtained in the dehydrogenation reaction. This improvement in catalytic performances could be attributed to the strong surface interactions, which modified the surface properties of the active platinum metal and the support, and further improved the catalytic performance of Pt-based catalyst.
