Cold Start Wetting Effect on the Catalytic Propertyand Hydrothermal Stability of a Cu-SSZ-13 Catalyst for NH 3 ‑SCR

The cold start wetting effect on Cu-SSZ-13 has been simulated via soaking catalysts with various Si/Al ratios in ammonium water at disparate pH levels. It is found that a mild treatment (pH = 9) ha...
