Abstract
The N.sub.2 O values in gaseous effluents, notably those produced in various organic syntheses entailing nitric acid oxidation (for example the industrial scale production of adipic acid, of glyoxal and of glyoxylic acid), are catalytically decomposed at elevated temperatures over H-mordenite and ammonium mordenite catalysts, preferably the ammonium mordenites that have been exchanged with iron, cobalt or bismuth.
