The Study about the Performance ofComplete Oxidation of Supported Palladium Catalyst

Novel catalyst with high activity for complete oxidation of benzene vapor was obtained. This palladium catalyst is supported on Fe-Cr-Al alloy containing rare earth. The performance of the catalyst is studied by using XRD and SEM techniques. The results of the test reveal that complete oxidation temperature for benzene vapor is 240℃ after the catalyst is heated for 2 hours at 900℃. The best method to prepare this catalyst was selected and the catalysis mechanism is studied. This catalyst deserves further investigation in later study.
