Steam reforming of propane over Ni-based oxide catalysts for hydrogen station and fuel processor applications was investigated. The nickel-based catalysts (12 wt% Ni/S, S=Al2O3, MgO) were prepared by an impregnation method. The prepared catalyst was characterized by N2 physisoprtion, CO chemisorption, TPR, XRD, and SEM. It was found that BET surface area of Ni/Al2O3 catalyst was higher than that of the other catalyst. In the TPR profiles, the peak was observed over Ni/Al2O3 at around 800℃, but no peak was indicated over Ni/MgO even at 1000℃. In the steam reforming reaction of propane, Ni/MgO catalyst showed higher H2 yield and catalytic stability than Ni/Al2O3 in the entire reaction range. The results suggested that Ni/MgO catalyst is a promising candidate for the production of hydrogen by the steam reforming of propane. |
