ABSTRACT:
Process for purification of essentially oxygen-free process gases by catalytic oxidation of the oxidizable, mainly organic impurities with the addition of a oxygen-containing gas, where oxygen-containing gas is added to the process gas in an amount responsive to the carbon monoxide content of the process gas measured after oxidation. The carbon monoxide set point is in the range of 10 to 1000 vpm.
