Abstract: A detailed study on the promotion effect of Zr on Mo-V mixed oxide catalysts in the selective oxidation of propane to acrolein was performed. The catalysts were characterized by BET, XRD, H2-TPR, NH3-TPD and isopropanol decomposition reaction. The addition of Zr modifies the catalysts phase composition and improves their redox and acid-base properties. As a result, the higher catalytic activity and selectivity were obtained over Mo2VZr0.5Ox catalyst.

Key words: Propane, Selective oxidation, Acrolein, Mo-V-O based catalyst
