Abstract

A molybdenum-vanadium bimetal oxide catalyst having a molecular formula of MoV, where y represents an atomic molar ratio of vanadium and molybdenum. An oxygen support MoVis prepared by an impregnation method including impregnation, drying, calcination, and tablet pressing. In the dehydrogenation reaction of a light alkane to an alkene over the supported molybdenum-vanadium bimetal oxide, the reaction temperature is 450° C.-550° C. Propane can be oxidized and dehydrogenated to produce propylene with a high activity and high selectivity. A conversion rate of propane remains at 30%-40%, and a selectivity for propylene is 80%-90%. A fresh oxygen support changes from a high-valence state to a low-valence state after reacting with propane. A low-valence state oxygen support reacts with air or oxygen to be oxidized to a high-valence state, and recovers lattice oxygen and cycles again.
