This study was conducted to figure out to convert to useful syngas(H2/CO) and the resistance coke in combined steam and carbon dioxide reforming(CSCRM) of methane. The catalyst was modified with different loading of Fe(0 - 5 wt%) over Ni(10)-Mg(1)-Ce(1)/ γ-Al2O3 by the impregnation. Catalysts was calcined at 900 °C, 5hr with Ar carrier gas and tested at 800 °C , 1 atm with feed ratio of CH4 : CO2 : H2O : Ar = 1 : 1 : 0.7 : 1 and GHSV = 40,000 h-1 for 8 hours. In conclusion, Ni-Mg-Ce -Fe/γ- Al2O3 showed the strong resistance toward carbon formation and improved the catalytic activity compared with , Ni-Mg-Ce/ γ- Al2O3. Among them, , Ni-Mg-Ce –Fe(5)/γ- Al2O3 obtained the long-term stability . |
