| Abstract | Carbon dioxide reforming of methane was carried out on supported nickel catalysts. The effect of different types of supports on the activity of nickel catalysts was investigated. Two types of supports, i.e. alumina in different phases and zeolite Y were adopted in this study. It has been found that 7%Ni/50%χ-γ-alumina exhibited the highest conversion as well as the highest coke resistance of all the catalysts studied. When compared between the mixed phase alumina and zeolite Y supported nickel catalysts, the former was found to possess both higher activity and stability than the letter. In addition, the comparison of mixed phase alumina supported catalyst with the commercial silica-magnesium oxide supported one was also made for carbon dioxide reforming of methane at the same conditions. Though the commercial silica-magnesium oxide supported nickel catalyst exerted higher conversion than did the mixed phase alumina supported one; however, the mixed phase alumina supported catalyst still showed essentially better stability. |
