Abstract: | Catalytic oxidation of propane to produce propene was investigated over molybdenum-based mixed oxide catalysts. Cobalt or
magnesium oxide combined with molybdenum oxide exhibits the best catalytic performance for the oxidative dehydrogenation of
propane. Catalytic activities of both Co-Mo-O and Mg-Mo-O vary drastically on the catalyst composition and Co(Mg)0.95Mo1.0Ox having small amounts of free MoO3 on the Co(Mg)MoO4 surface shows the highest catalytic activity keeping a considerably high selectivity to propene. The catalytic activity also
depends strongly on the acidic properties of catalysts and MoO3 clusters formed on the surface of Co(Mg)MoO4 are responsible for the activities for the oxidative dehydrogenation of propane. |
