Carbon dioxide reforming of methane to synthesis gas on Ni/MgO catalysts: Effect of calcination temperature

The catalytic performance of Ni/MgO catalysts in CO2 reforming of methane and the calcination temperatures influencing of catalysts activity were investigated by a comparative study of different reduced nickel magnesia catalysts. The catalysts were characterized by BET, XRD and TPR techniques. It was found that the excellent performance and stability of the reduced catalyst that was calcinated on lower temperatures is attributable to high dispersion of the reduced Ni species, easy reduction of NiO, and lower agglomerating of the active metal
