Methanol oxidation reforming over a ZnO-Cr2O3/CeO2-ZrO2/Al2O3 catalyst in a monolithic reactor

Catalysts with a high activity and a high stability play an important role in the process of hydrogen generation via methanol oxidation reforming for PEM fuel cell. In this paper, catalysts with high activities and selectivities for methanol oxidation reforming have been developed. The reaction experimental results indicate that a ZnO-Cr2O3/CeO2-ZrO2/Al2O3 ceramic monolithic catalyst is a promising catalyst for the hydrogen production from methanol oxidation reforming. There was no significant deactivation of the catalyst over 1000 h of continuous operation and the CO concentration in the reformate effluent dry gas was less than 1.4%, and methane produced was negligible under the molar ratios of O2/MeOH = 0.3, H2O/MeOH = 1.2, and gas hourly space velocity equal to 3850 h−1.
