Effect of CeO2 Promoter on the Performance of Catalyst for CH4, CO2with O2 to Synthesis Gas
摘要:
In the reaction of methane, carbon dioxide with oxygen to synthesis gas, conversion of CH4 was increased, but CO selectivity was reduced when CeO2 was added to Ni/Ca0-Al2O4 catalyst.The characterization of TPR, XPS, XRD and H2-TPD exhibited that, on one hand, the CeO2 promoter decreased the reduction temperature of catalyst.On the other hand, addition of CeO2 resulted in an increase in the electron density of active component Ni, and as a result, reduced the ability of CH4 deep cracking and enhanced the resistance to carbon-deposition of catalyst.In addition; the existence of CeO2 was beneficial to decrease the Ni crystal particle size.
