Abstract

In a method and apparatus for selective catalytic oxidation of carbon monoxide, the gas mixture and an additionally added oxidizing gas are conducted through a reactor containing the catalyst. Oxidizing gas is added at several points along the mixed gas flow path with a controlled or regulated through flow volume. The mixed gas stream is cooled passively by static mixing structures located in the inlet area of the CO-oxidation reactor. By controlling exothermal CO oxidation along the reactor path, a very variable process guidance is provided, that can be adjusted to individual situations.
