A preparation method of SSZ-16 copper-containing catalyst. The method adopts six-membered ring double-substituted quaternary ammonium salt as organic template agent, uses FAU type silica-alumina molecular sieve, and combines alkali source, silicon source, aluminum source and crystal seed in deionized water to uniformly mix to form a solution, and through dynamic crystallization hydrothermal Synthesize SSZ-16 molecular sieve, disperse the molecular sieve in the copper salt solution, and obtain SSZ-16 copper-containing catalyst after stirring, filtering, washing, drying and roasting. Its high specific surface area and high hydrothermal stability enable the material to have high NH 3 ‑SCR activity, selectivity and service life. |
