The oxidation stability of a low surface area Mo2C catalyst has been studied in the presence of gases associated with the steam and dry (CO2) reforming of methane, at temperatures up to 850°C and pressures to 8 bar. The oxidation onset temperatures were found to be about 600°C when the carbide was exposed to either steam or CO2. There appears to be two distinct mechanisms for Mo2C oxidation: direct oxidation at low temperatures and thermal decomposition followed by oxidation of the Mo metal at temperatures above 750°C. Although onset temperatures were similar, CO2 was a stronger oxidant than steam at the higher temperatures. Both H2 and CO were found to inhibit oxidation and the effect can be explained by their influence on the prevailing kinetics. Trace concentrations of methane were found to completely stabilize the carbide from steam oxidation but significantly higher concentrations were required to stabilize it from CO2 oxidation and this is attributed to the higher rates of CO2 oxidation relative to carburization rates. The effect of pressure on the onset temperature of CO2 oxidation of the carbide was found to be negligible, even when inhibited by CO.
