Method for producing SCR active zeolite catalyst and SCR active zeolite catalyst |
| abstract |
A method for producing an SCR active zeolite catalyst and a zeolite catalyst produced thereby are disclosed. In order to produce the catalyst, first the Fe ion exchanged zeolite is subjected to a first temperature treatment (3) in the range of 300 ° C. to 600 ° C. in a reducing hydrocarbon atmosphere, thus Fe Fe. The oxidation state of the ions is reduced and / or the degree of dispersion of the Fe ions on the zeolite is increased, after which the reduced zeolite is subjected to a second temperature treatment in the range of 300 ° C. to 600 ° C. in an oxidizing atmosphere. Subjected to (4), thus hydrocarbon residues or carbon residues are oxidatively removed and the zeolite is calcined (1) between the first and second temperature treatments to provide a catalyst. Within the temperature range below 300 ° C. by stabilizing the iron contained in the zeolite in an oxidation state of less than +3 and / or permanently increasing the degree of dispersion of Fe ions on the zeolite by said production method. A high SCR activity can be achieved. [Selection] Figure 1 |
