Abstract

Procédé pour abaisser la concentration en polluants dans les gaz usés par traitement thermique et/ou catalytique oxydant, suivant lequel dans le cas de gaz usés contenant des composés organiques azotés et/ou du cyanure d'hydrogène, on soumet en succession du traitement oxydant, thermique et/ou catalytique (3), le courant de gaz résultant à un traitement catalytique au cours d'un stade supplémentaire (8) avec apport d'ammoniac. Le catalyseur est à base de métal noble du groupe du platine et/ou de vanadium.
