  • Patent number: 8623781
    Abstract: The oxidative dehydrogenation of propane provides a highly selective catalyst for the oxidative dehydrogenation of propane to propylene, and a process for preparing the catalyst. The catalyst is a mixed metal oxides catalyst of the general formula MoaVbOx, where the molar ratio of molybdenum to vanadium is between 1:1 and 9:1 (a:b is between 0.5:0.5 and 0.9:0.1) and x is determined according to the oxidation state of the cations present. The catalyst is prepared by mixing the metals by sol-gel technique, heating the gel to dry the mixed oxides, further heating the dried product to induce auto-combustion, washing the product with isopropyl alcohol, and drying with a supercritical CO2 dryer. Oxidative dehydrogenation is carried out by contacting a stream of propane gas with the bulk mixed metal oxides catalyst at a temperature between 350° C. and 550° C. Propylene selectivity of 100% is reached at conversion rates between 1.9% and 4.8%.
