چکیده انگلیسی
Nickel catalysts supported on CeO2-ZrO2-CeO2, ZrO2-Al2O3 and Al2O3 were prepared and characterized by means of X-ray diffraction (XRD), BET areas, H2 temperature-programmed reduction (H2-TPR), and X-ray photoelectron spectroscopy (XPS). Through the test of catalytic partial oxidation of methane (CPOM), Ni/CeO2-ZrO2-Al2O3 displayed the highest activity, which resulted from its largest BET area and best NiO dispersion. Furthermore, Ni/CeO2-ZrO2-Al2O3 maintained a long-time stability in CPOM, which was attributed to its best coking resistance among all the prepared catalysts.
