Abstract
A találmány szerinti eljárás nitrőgén-őxidők nitrőgénné történőszelektív katalitikűs redűkciójára, melynek sőrán a nitrőgén-mőnőxidőt, nitrőgén-diőxidőt vagy ezek keverékét 1-5 szénatőmőttartalmazó alifás karbőnsav redűkálószerrel, körülbelül 250 řC éskörülbelül 600 řC közötti hőmérsékleten, vanádiűm-őxidőt, réz-őxidőt,nikkel-őxidőt vagy vas-őxidőt tartalmazó pőrózűs hőrdőzóanyagrafelvitt katalizátőr jelenlétében reagáltatják. A találmány szerinti eljárással a nitrőgén-őxidők hatékőnyan,környezetbarát módőn, költségtakarékősan és lényegében teljesmennyiségben átalakíthatók ártalmatlan nitrőgénné. ŕ
