Abstract

The catalytic performance and the sulphur resistance of a Pd (0.7 wt%) catalyst supported over Co3O4(30 wt%)–CeO2(70 wt%) mixed oxide were investigated in the oxidation of methane under stoichiometric and lean conditions. The catalytic behaviour was compared with that of two reference catalysts, palladium supported over pure Co3O4 and CeO2. Catalysts were characterized by XRD, BET, XPS and FTIR measurements. Regeneration by a CH4-reducing treatment at 600 °C was investigated.
