Amorphous ZrO2 Modified CuO-ZnO Catalyst for Low Temperature Removal of Carbon Monoxide

Removal of trace amount of CO followed the redox mechanism: lattice oxygen in the catalyst reacted with CO  in the olefin stream. Introduction of  amorphous ZrO₂ to CuO-ZnO catalyst  improved the removal efficiency.Experimenatal investigation showed that it resulted in  the improved dispersion of micro-CuO  and  synergistic effect between CuO and ZrO₂.
