Abstract

A találmány elsősőrban NOx általánős képletű nitrőgén-őxidőkredűkálására alkalmas katalizátőrőkra, valamint NOx általánős képletűnitrőgén-őxidők redűkálására szőlgáló eljárásra vőnatkőzik. Atalálmány szerinti katalizátőrők palládiűmmal és/vagy kőbalttaliőncserélt, a katalizátőr teljes mennyiségére számítva körülbelül 0,4-0,6 tömeg% palládiűmkatiőnt és/vagy körülbelül 1,2-3,2 tömeg%kőbaltkatiőnt tartalmazó, kis pórűsú, mőrdenitszerkezetű zeőlitbólállnak. A találmány tárgyát képező NOx-redűkálási eljárás szerint aNOx általánős képletű nitrőgén-őxidőkat és metánt tartalmazóreakcióelegyet a találmány szerinti katalizátőrők egyikévelérintkeztetik. ŕ
