英文摘要: The Co-mcorporated Ce1-xZrxO2 catalysts were prepared by co-precipitation for carbon dioxide reforming of methane The ratio of Cc to Zr was varied to optimize the performances of co-precipitated Co-Cc-Zr-x, catalysts The prepared catalysts were characterized by various physico-chemical characterization techniques including TP12. X-ray diffraction, N-2 adsorption at low temperature. XPS and CO2-TPSR The co-precipitated Ce1-xZrxO2 202 sample containing 16% Co0 exhibited a higher catalytic activity among the five catalysts. and the activity was maintained without siumlicant loss during the reaction for 60 h Under the conditions of 750 C, 0 I MPa. 36000 mllil gcm). and CO2/C1-14 molar ratio of 1 I. the CO, conversion over this catalyst was 75% while the CI-14 conversion was 67% The cubic Ceo sZro 202 facilitated a higher dispersion and a highel reducibility of the cobalt component. and the apparent activation energy fol Co-Ceo sZro 207 sample was 49 1 kJ/mol in the CO2/CH4 reforming reaction As a result. the Co-Ceo sZro 202 sample exhibited a higher activity and stability for the reforming of CH4 with CO2
