摘要：The concentration of carbon monoxide in a gaseous medium is reduced by selective catalytic oxidation in the presence of gaseous oxygen by passing the gaseous medium through a catalyst capable of oxidizing carbon monoxide in an exothermic reaction at temperatures within a given temperature range and by controlling the temperatures encountered in the catalyst in such a manner that the exothermic reaction takes place first above a threshold temperature below which the catalyst would be rapidly inactivated at the relatively high carbon monoxide concentrations present in the gaseous medium as it enters the catalyst, and subsequently, after the carbon monoxide concentration has been reduced to an acceptable level, at less than the threshold temperature to further reduce the carbon monoxide concentration to a desired minimum level below that achievable at temperatures above the threshold temperature.
