| titleOfInvention | Preparation and application of an additive-doped Cu-SSZ-39 catalyst with high hydrothermal stability |
| abstract | The invention belongs to the technical field of catalytic materials, and in particular relates to the preparation and application of a high hydrothermal stability auxiliary-doped Cu-SSZ-39 catalyst. The invention uses SSZ-39 (AEI framework) molecular sieve as the catalyst, and Cu as the catalyst. The main active component, with Na, K or Ca as catalyst promoter, the prepared promoter-doped Cu-SSZ-39 catalyst is used for the selective catalytic reduction of NH 3 to eliminate NO x , which can reach >90 at 250℃ % NOx conversion, can reach >80% NOx conversion in the range of 250‑550℃, and after high temperature treatment at 750℃ or 800℃, it still has good NOx conversion rate and good hydrothermal stability , has excellent low-temperature NH 3 ‑SCR activity and high-temperature hydrothermal stability, and can be used as a denitration catalyst to eliminate nitrogen oxides in diesel exhaust. |
