Nickel catalysts (10 wt.%) supported on MgAl2O4 and -Al2O3 were prepared by the wet impregnation method and promoted with various content of Ce0.75Zr0.25O2. X-ray diffraction (XRD), BET surface area, H2-temperature programmed reduction (TPR) and CO2-temperature programmed desorption (TPD) were employed to observe the characteristics of the prepared catalysts. Ni/-Al2O3 without promoter and Ni/ Ce0.75Zr0.25O2(5%wt.)- MgAl2O4 showed better activity in CO2 methane reforming.
کلمات کلیدی: CeZrO2 promoter, CO2 reforming, MgAl2O4,-Al2O3
