제목 Syngas production from combined steam and carbon dioxide reforming over Ni-Mo-Sb/ γ-Al2O3 catalyst: Effect of Antimony
초록 The catalytic performance of Ni-Mo supported on Sb promoted γ- Al2O3 was evaluated in combined steam and carbon dioxide reforming(CSCRM) of methane. The catalyst was modified with different loading of Sb(1, 3 wt%) over Ni(12)-Mo(1)/ γ-Al2O3 by the impregnation. Catalysts was calcined at 750 °C, 5hr with Ar carrier gas and tested at 900 °C , 1 atm with feed ratio of CH4 : CO2 : H2O : Ar = 1 : 0.8 : 1.3 : 1 and WHSV = 40,000 h-1 for 8 hours.  
As a result, addition of Sb on Ni-Mo/ γ- Al2O3 had an effect on the strong resistance toward carbon formation and improved the catalytic activity. Among the catalysts investigated, the optimal catalytic activity and stability was achieved over the sample with 3 wt% of antimony.
