Improving the Physicochemical Properties ofSbVZrCe Catalyst Prepared By Reflux Method

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.
