摘要

A method for minimizing the emission of harmful substances from an effluent containing carbon monoxide, hydrocarbons and nitrogen oxides, which process comprises the steps of, successively; (a) oxidizing a part of the total oxidizable components existing in the effluent by introducing an oxygen-containing gas into said effluent, without completely oxidizing the carbon monoxide; (b) exposing said effluent to an environment to chemically reduce a substantial part of the nitrogen oxides; and (c) exposing said effluent to a gas containing oxygen to oxidize the oxidizable components remaining in said effluent.
