Abstract
Oxidative dehydrogenation (ODH) of alkanes to alkenes, e.g., propane to propylene, may use solid phase oxygen in VObased mixed oxide catalysts. Beyond catalysis, the metal oxide species provide lattice oxygen. The catalysts can be prepared by depositing vanadium oxide(s) on θ-AlOmixed with various alkaline earth metal oxide support, e.g., CaO, MgO, BaO, etc. Surface area, acidity, and reduction properties of the catalyst systems can be modified by the support. The catalysts may allow multistage reduction of VO, indicating different VOspecies. Vanadium on θ-AlO/CaO can suppress COx species, while vanadium on θ-AlO/BaO can yield at least ca. 49% olefins.
