Preparation, characterization and catalytic test of MoVSb and MoVNb mixed oxide catalysts for propane ammoxidation to acrylonitrile

Abstract

MoVSb and MoVNb mixed oxide catalysts were prepared using reflux method for the propane ammoxidation reaction to acrylonitrile. These catalysts were characterized using N2 physisorption (BET), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and catalytic tests. The catalytic testing shows that the MoVSbO catalyst has higher selectivity to ACN but lower conversion of propane as compared to MoVNbO catalyst. © Asian Network for Scientific Information.
