Fluidizable vanadium catalyst for oxidative dehydrogenation of alkanes to olefins in a gas phase oxygen free environment

Fluidizable catalysts for the gas phase oxygen-free oxidative dehydrogenation of alkanes, such as propane, to corresponding olefins, such as propylene. The catalysts comprise 5-20% by weight per total catalyst weight of one or more vanadium oxides (VOx), such as V2O5. The dehydrogenation catalysts a...

Beschreibung
Zusammenfassung:	Fluidizable catalysts for the gas phase oxygen-free oxidative dehydrogenation of alkanes, such as propane, to corresponding olefins, such as propylene. The catalysts comprise 5-20% by weight per total catalyst weight of one or more vanadium oxides (VOx), such as V2O5. The dehydrogenation catalysts are disposed on an alumina support that is modified with calcium oxide to influence characteristics of lattice oxygen at the catalyst surface. Various methods of preparing and characterizing the catalyst as well as methods for the gas phase oxygen free oxidative dehydrogenation of alkanes, such as propane, to corresponding olefins, such as propylene, with improved alkane conversion and olefin product selectivity are also disclosed.
