Abstract

Det beskrives en fremgangsmåte for minskning av innholdet av NOx og N2O i gasser, spesielt i prosessgasser og avgasser, omfattende tiltakene: a) å tilsette minst ett nitrogenholdig reduksjonsmiddel til den NOx og N2O holdige gassen i en slik mengde som minst er nødvendig for fullstendig reduksjon av NOx b) å tilsette et hydrokarbon, karbonmonoksid, hydrogen eller en blanding av en eller flere av disse gasser til den NOx og N2O holdige gassen før reduksjonen av N2O og c) å føre gassblandingen inn i minst en reaksjonssone med en temperatur på opp til 450 oC som inneholder en eller flere med jernladede zeolitter. Fremgangsmåten kan spesielt anvendes ved salpetersyreproduksjon, på kraftverksavgasser og til gassturbiner.
