Green Valley Environmental Protection | Technical Report on SCR Control System (Chapter 2)
Engineering Implementation of ASC ASC adopts a dual-layer catalyst design, which is the mainstream solution for field applications: Upper-layer catalyst: Pt/Al₂O₃ — efficiently oxidizes NH₃ into N₂, N₂O and H₂O. Platinum delivers the highest activity for NH₃ oxidation, yet it may also over-oxidi...
