Enhancement of Dry Reforming of Methane Using Different Catalysts

In this study, the conversion of methane and carbon dioxide to synthesis gas using dry reforming of methane over Ni, Pd, and Pt/MgO catalysts in different concentrations of Ce3+, Ce4+and Ni2+ was prepared via the co-precipitation of Mg and Ce nitrates, followed by impregnation with 1 wt.% each of Ni, Pd, and Pt metals to form Pt/Mg1-xNixO, Pd/Mg1-xCe3+xO, Pd/Mg1-xCe4+xO, and Ni,Pd,Pt/Mg1-xCexO catalysts. The goal of this study was to prepare a catalyst with high activity and selectivity to prevent carbon deposition onto the catalyst during the syngas production and to investigate the factors affecting carbon deposition.
