FIELD: environmental protection.
SUBSTANCE: method comprises adding at least one nitrogen-containing reducer to the industrial exhaust gas containing NOx and N2O in amount sufficient for at least complete reduction of NOx. The mixture produced is supplemented with hydrocarbon, monoxide of carbon, hydrogen or a mixture of these gases for reducing N2O and is forced to flow through at least one reaction zone at a temperature up to 450°C.
EFFECT: enhanced efficiency.
