DRY REFORMING OF METHANE OVER SUPPORTED NICKEL CATALYSTS PROMOTED BY ZERCONIA, CERIA AND MAGNESIA

Dry reforming of methane (DRM) is an environmental friendly process to produce synthes is gas (H 2 + CO). The catalysts used are often composed of transition metals like nickel , supported on metallic and non - metallic oxides such as alumina along with promoters or without promoters . The deactivation of catalysts is a major problem due to carbon deposition. In the present paper alumina supported nickel catalysts promoted by zirconia, ceria and magnesia are reported for the methane dry reforming in order to improve the activity and stability of the catalysts .
