Abstract

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 Cu^II 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 0.18^th order in methanol and oxygen and -0.14^th order in water. The apparent activation energy was 115+/-6 kJ/mol.
