Catalytic Activity Of Y Zeolite Supported Ceo2 Catalysts For Deep Oxidation Of 1, 2-Dichloroethane (Dce)

Three Y zeolites supported CeO2 catalysts (CeO2/USY, CeO2/HY, CeO2/SSY) were prepared and used for deep oxidation of 1,2-dichloroethane (DCE) in low concentration (about 1,000 ppm). The catalysts were characterized by XRD, N-2 adsorption/desorption and H-2-TPR. The results showed that the catalytic activity of the supported CeO2 catalysts was much higher than that of Y zeolites, in particular, CeO2/USY exhibited the highest activity, T-98% values of DCE was about 270 A degrees C. And the catalytic activity was strongly related to the interaction between CeO2 and Y zeolites.
