Ni-based Catalyst for Steam Reforming of LPG in Hydrogen Station and Fuel Processor |
| 초록 |
The steam reforming of LPG over Ni-based oxide catalysts for hydrogen station and fuel processor applications was investigated. The supported nickel catalysts (12wt% Ni/S, S=Al2O3, MgO and CeO2) were prepared by impregnation method. The prepared catalyst was characterized by N2 physisoprtion, CO chemisorption, XRD, SEM, TPR and XPS. It was found that BET surface area of Ni/MgO catalyst was higher than these of the other catalysts. The H2 concentration over Ni/MgO catalyst did not changed under the tested conditions, but that over Ni/Al2O3 slowly decreased at less than 700℃. It was also found that methane over Ni/MgO catalyst was produced at less than 650℃, but that over Ni/Al2O3 was formed under 750℃. There is no major changes in the X-ray diffraction patterns of the Ni/MgO catalysts before and after the reaction but nickel carbide (NiC) phase over Ni/Al2O3 catalyst after the reaction was confirmed. It was concluded that Ni/MgO catalyst is a promising candidate for the production of hydrogen by the steam reforming of LPG. |
