Zusammenfassung:The invention relates to a method for removing ammoniacal components of a flue gas that has been treated according to the SNCR method, wherein the method is characterized in that the flue gas is contacted at a temperature, that is at least 150° C. below that at which the SNCR method is carried out, with a ferro-oxidic catalyst having a specific surface area of at least 0.2 m /g, measured according to the BET method. Preferably, the catalyst is added to the flue gas at a temperature of 700-400° C. of the gas in the flue channel.
