Pt–Ga Catalysts Based on Highly Porous Silica MCM-41 for Propane Dehydrogenation

Highly porous SiO supports with the MCM-41 structure were synthesized by template method. Pt–Ga catalysts for propane dehydrogenation were obtained using the impregnation method. The structure of the synthesized samples was studied by low-temperature nitrogen adsorption and X-ray phase analysis (XRD), and the properties of catalyst reduction were studied by temperature-programmed reduction in hydrogen (TPR-H). The catalytic properties were studied in the reaction of propane dehydrogenation, and the influence of hydrogen in the composition of the reaction mixture was studied. It has been shown that the addition of hydrogen into the reaction mixture leads to an increase in the stability and activity of platinum catalysts.
