Ammoxidation of Propane over V/Sb Catalysts

Abstract

Abstract: The ammoxidation of propane was studied over the V/Sb oxide catalysts.The effects of the catalyst composition, structure, reactivity of labile oxygen and surface base-acidity on the catalytic acitivty have been examined by using XRD, TPD-O₂, TPRand TPD-NH₃. The experiment found that the catalyst with V/Sb=1/5 gave higher activity and selectivity.The results show that the active phase is VSbO₄ in the catalyst, the synergistic effects between VSbO₄ and Sb₂O₄ phases have an important influence on the activity of the catalyst.

Key words: Propane, Ammoxidation, Vanadium-antimony oxide
