Abstract (en)
[origin: WO2017178575A1] The invention relates to a catalyst, which comprises a catalyst substrate of the length L and two SCR-catalytically active materials A and B, wherein the SCR-catalytically active material A contains a zeolite of the levyne structure type, which contains ion-exchanged iron and/or copper, and the SCR-catalytically active material B contains a zeolite of the chabazite structure type, which contains ion-exchanged iron and/or copper, wherein (i) the SCR-catalytically active materials A and B are in the form of two material zones A and B, wherein material zone A extends from the first end of the catalyst substrate at least over part of the length L and material zone B extends from the second end of the catalyst substrate at least over part of the length L, or wherein (ii) the catalyst substrate is formed by the SCR-catalytically active material A or B and a matrix component and the SCR-catalytically active material B or A extends at least over part of the length L of the catalyst substrate in the form of a material zone B or A.
