| titleOfInvention | A kind of hollow Cu-SSZ-13 molecular sieve catalyst and its application |
| abstract | The invention discloses a method for preparing a hollow structure Cu‑SSZ‑13 molecular sieve and a method for selectively catalyzing NH3 to reduce NO. The gel formed by mixing is subjected to one-step hydrothermal crystallization to directly produce a hollow single crystal SSZ‑13 molecular sieve; then perform NH 4 + and Cu 2+ ion exchange respectively, centrifugal washing, drying, and roasting to obtain a hollow structure Cu‑SSZ‑ 13 molecular sieve; finally, under the catalysis of hollow structure Cu‑SSZ‑13 molecular sieve, NO is selectively reduced to N 2 by using NH 3 as a reducing agent. The invention prepares the hollow structure SSZ-13 molecular sieve by one-step hydrothermal method, which is more economical, simple and efficient compared with the traditional two-step acid-base treatment method; at the same time, in the NO reduction reaction, it is beneficial to the mass transfer and diffusion of each reaction molecule , thereby effectively improving the activity of NO reduction, broadening the activity window, and being more suitable for NO reduction reaction under high space velocity conditions. |
