Abstract

The effects of MgO loading and calcination temperature of the catalysts on the carbon dioxide reforming of methane (CDR) have been extensively investigated over Ni/MgO/Al2O3 catalysts in a fixed-bed reactor system. Results indicate that the activity and stability of the catalysts were significantly influenced by both MgO loading and calcination temperature, i.e., higher calcination temperature and higher MgO loading are essential for high activity and stability of the catalyst. Characterization results indicate that mixed spinel phase composed of MgAl2O4 and NiAl2O4 is effective to produce active and stable Ni species having strong Ni to support interaction resulting in active and stable catalytic performance in CDR.
