Abstract

A találmány tárgya eljárás üzemi gázok és hulladék gázok NOX és N2Otartalmának csökkentésére, oly módon, hogy az eljárást lényegében egyvagy több, vassal töltött zeolitot tartalmazó katalizátor jelenlétébenvégzik, és az N2O és NOX tartalmú gázt az N2O eltávolítására egy elsőlépésben egy I. reakciózónában 500 °C alatti hőmérsékleten átvezetjüka katalizátoron, és a kapott gázáramot egy második lépésben egy II.reakciózónában tovább vezetik egy vastartalmú zeolit katalizátoron,ahol a gázáramba a II. reakciózónába történő belépés előtt az NOXredukálására elegendő mennyiségű NH3 gázt vezetnek. A találmánykiterjed a fenti eljárás megvalósítására alkalmas berendezésre. Ó
