Hydrotalcite-like precursors were synthesized by conventional co-precipitation method.NiMgAl, NiMgAl-Mo and NiMgAl-MoCe composite oxides derived from the calcination of the precursors were employed as catalysts in carbon dioxide reforming of methane for catalytic performances evaluation.The effect of addition of Mo and Ce as promoters on the catalytic activity was mainly investigated, especially on the reactant gas conversion.X-ray diffraction and N2 adsorption-desorption techniques were employed for the structural investigation of the catalysts.The reduction properties of the catalysts were evaluated via H2 temperature programmed reduction process.The results present that, all the NiMgAl, NiMgAl-Mo and NiMgAl-MoCe catalysts derived from hydrotalcite-like compounds presented features of mesoporous materials.The addition of Mo and Ce elements to the NiMgAl decreased the BET surface areas and influenced the reduction temperatures of catalysts.The catalytic performance results exhibit that the NiMgAl catalyst afforded the poorest activity with the lowest conversion of both CH4 and CO2 at temperatures from 650 to 1 000 ℃.The addition of Mo to NiMgAl promoted the conversion of both methane and carbon dioxide.However, further addition of Ce to NiMgAl-Mo only improved the conversion of methane while the conversion of carbon dioxide was inhibited.
