Antimony-vanadium-oxide is known to be an active and selective catalyst for the ammoxidation of propane to Acrylonitrile(ACN) and doping with Zr-Ce can enhance the performance ofthis catalyst. Unfortunately the yield of21.3% is to low to be used commercially. Sb-V-Zr-Cecatalyst is prepared by using slurry method for the ammoxidation of propane to ACN. In an attemptto increasethe yield of propane to ACN, modifications methods solely focus on reflux method are introduced into the catalyst preparation method for this process. A combination of various physicochemical techniques such as FTIR, physical adsorption ofN2, BET surface area, X-ray Diffraction (XRD), scanning electron microscopy (SEM) and Temperature Programmed Desorption Reduction & Oxidation (TPDRO) are used to characterize the modified catalyst.
