Oxalic Acid Activation of the Mechanochemical Synthesis of Copper–Zinc–Aluminum Catalysts for Steam Conversion of Carbon Monoxide

Abstract

Catalysts for steam conversion of carbon monoxide of the composition 44 wt % CuО, 45 wt % ZnО, and 11 wt % Al₂О₃ were prepared by the mechanochemical procedure in the presence of oxalic acid. The catalysts were tested in steam conversion of carbon monoxide. The effect of oxalic acid introduced in the course of the synthesis on the specific surface area of the catalyst samples and on the catalyst performance with respect to carbon monoxide was demonstrated.
