主　　题：combined reaction partial oxidation of methane carbon dioxide reforming of methane synthesis gas ruthenium 

摘      要：Combination of partial oxidation of methane （POM） with carbon dioxide reforming of methane （CRM） has been studied over Ru-based catalysts at 550℃.POM,CRM and combined reaction were performed over 8wt%Ru/γ-Al2O 3 and the results show that both POM and CRM contribute to the combined reaction,between which POM plays a more important ***,the addition of Ce to Ru-based catalyst results in an improvement in the activity and CO selectivity under the adopted reaction *** Ce-doped catalyst was characterized by N2 adsorption-desorption,SEM,XRD,TPR,XPS and in situ *** mechanism has been studied by in situ DRIFTS together with the temperature distribution of catalyst *** mechanism of the combined reaction is more complicated and it is the combination of POM and CRM mechanisms in *** present paper provides a new catalytic system to activate CH4 and CO2 at a rather low temperature.
