Resumen

The Al₂O₃-supported Pt-Sn catalysts were prepared utilizing an impregnation-reduction method and applied in the propane dehydrogenation in the presence of air. The addition of air, it not only provides a part of the heat required by dehydrogenation, but also improves the reaction conversion through the consumption of H₂ to H₂O. Moreover, the operating conditions of the dehydrogenation process with air have been investigated. The reasonable operating conditions are recommended as follows: temperature=590 °C, GHSV=5200 h^-1, and C₃H₈: air: H₂=4:5:4 (molar ratio). Under these conditions, the propane conversion and the propene selectivity attain 39.6% and 96.7%, respectively, simultaneously with the stable catalytic activity.
