Publication number: 20120208692Abstract: An SCR-active zeolite catalyst and a method for producing same. To produce the catalyst, an Fe ion-exchanged zeolite is initially subjected to a first temperature treatment within a range of 300 to 600° C. in a reducing hydrocarbon atmosphere such that the oxidation state of the Fe ions decreases and/or the dispersity of the Fe ions on the zeolite increases, whereupon the reduced zeolite is subjected to a second temperature treatment within a range of 300 to 600° C. in an oxidizing atmosphere such that hydrocarbon residues or carbon residues are oxidatively removed, the zeolite being calcined to obtain a catalyst material during the two temperature treatments. Iron contained in the zeolite is stabilized in an oxidation state of less than +3 and/or the dispersity of the Fe ions on the zeolite is permanently increased such that a high SCR activity is achieved within a temperature range of less than 300° C.Type: ApplicationFiled: August 21, 2010Publication date: August 16, 2012Applicant: JOHNSON MATTHEY CATALYSTS (GERMANY) GMBHInventors: Jorg Werner Munch, Ralf Dotzel
