The DRM reaction converts CH4 and CO2 intosynthesis gas (CO + H2), which is a basis for the synthesis ofoxygenated chemicals such as acetic acid, dimethyl ether, andoxo-alcohols. CeO2, ZrO2, and CeO2–ZrO2 supported on MgO–promoted Ni catalysts are developed and applied to thereforming of methane with carbondioxide. Ni–MgO–Ce0.8Zr0.2O2 catalyst shows high activity as well as stability with time on stream.Thesize of the Ni particles and the oxygen storage capacity are found to be theprimary and secondary key factors that influence the catalytic performancerespectively. The Ni–MgO–Ce0.8Zr0.2O2 catalyst showed the best performance for the reforming of methane with carbon dioxide because of thehigh reduction degree and small Ni particle size.In the present study,we focus on the variation of Ni particle size and oxygenstorage capacity with the CeO2–ZrO2 compositionNi–MgO–Ce0.8Zr0.2O2 support to further improve the performance of the catalyst. |
