Propane Dehydrogenation over PtSn/Al2O3 Catalysts: Influence of Urea to Al(NO3)3•9H2O Ratio

Xiaohan Wang et al.

Summary: In this study, Al2O3 supports were synthesized by the hydrothermal method and PtSn/Al2O3 catalysts were prepared by incipient-wetness impregnation method. The results showed that the ratios of urea to Al(NO3)(3)center dot 9H(2)O influenced the morphology and phy-chemical properties of Al2O3 support, which in turn affected the dispersion of PtSn active sites and the interaction of Pt and Sn on PtSn/Al2O3 catalysts. The PtSn/Al2O3-9 catalyst exhibited the highest interaction of Pt and Sn, resulting in high dispersion of active sites and showed high propane conversion and low deactivation rate among these catalysts.

Summary: A strategy was developed to enhance the intrinsic activity and coking-resistance of supported VOx catalysts, by adjusting the annealing temperature and VOx surface density, in order to tailor the dispersion of VOx and the micro-environment of V-O-Al active sites.
