<p>A device and method for the reduction of NOx and N2O content in process gases and exhaust gases are disclosed. The device comprises at least one catalyst bed, containing a catalyst, with essentially one, or several, ironloaded zeolites and two reaction zones, whereby the first zone (Reaction zone I) serves for the decomposition of N2O and in the second zone (Reaction zone II) NOx is reduced. A device for the introduction of NH3 gas is situated between the first and second zones.</p> |
