Carbon monoxide clean-up of reformate gas by preferential oxidation
… Increasing temperature increased CO conversion up to a maximum after which a further increase in temperature led to a decrease in CO conversion. At low temperatures, increasing space velocity resulted in a decrease in CO conversion. An increase in CO conversion was observed with increasing space …
