The oxidative methanol reforming reaction over CuO/ZnO/Al2O3 was studied in a flow reactor. The catalyst performance was found to be a strong function of the copper oxidation state. In the presence of gaseous O2, when CuII is present, oxidation of methanol to H2O and CO2 was dominant with only minor H2 production. Under these conditions, thermal deactivation was found to occur. For temperatures from 180-225°C, the kinetics of the oxidation reaction was found to be 0.18th order in methanol and oxygen and -0.14th order in water. The apparent activation energy was 115+/-6 kJ/mol.
