Study on the Catalytic Performance of Metal Oxide-modified Pt-based Catalysts for Propane Dehydrogenation
A series of Pt-based catalysts,including Pt-LaGaO3/SiO2,Pt-LaGaO3/Al2O3,Pt-LaAlO3/SiO2,Pt-La2O3/SiO2 and Pt-Ga2O3/SiO2,were prepared by adding metal oxides to the support SiO2 or Al2O3.The effect of metal oxide modification on the propane dehydrogenation performance of Pt active centers was investigated.The experimental results indicate that the composite metal oxide-modified Pt catalysts with suitable composition and structure can greatly improve the propane dehydrogenation performance of the catalyst.
