Abstract
The oxidative methanol reforming reaction over CuO/ZnO/Al 2 O 3 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 O 2 , when Cu II is present, oxidation of methanol to H 2 O and CO 2 was dominant with only minor H 2 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 0.18 th order in methanol and oxygen and −0.14 th order in water. The apparent activation energy was 115+/−6 kJ/mol.
