چکیده انگلیسی
The effect of preparation method and pretreatment on the characteristic properties and selective CO oxidation activities of 50/50 CuO/CeO2, 25/25/50 CuO/Co3O4/CeO2 and 5/95 CuO/CeO2 catalysts was investigated. Catalysts were characterized by BET surface area measurement, N2 physisorption, SEM micrographs and X-ray diffraction. The selective oxidation reaction in H2 rich stream was carried out between the 110 °C and 210 °C temperatures. The 5/95 CuO/CeO2 catalysts gave the best CO conversion and selectivity result. The 5/95 CuO/CeO2 catalyst calcined at 700 °C protected its activity and selectivity at 200 °C during 24 h.
