Catalysts for the reduction of ammonia emission from rich-burn exhaust |
| 摘要 |
Provided is a system for reducing ammonia (NH3) emissions comprising a substrate and an ammonia oxidation catalyst disposed thereon, wherein the ammonia oxidation catalyst comprises a small pore molecular sieve supporting a transition metal selected from Cu, Fe, Ce, Mn, Ni, Zn, Ga, Mo, and Cr, provided that the ammonia oxidation catalyst is effective at oxidizing ammonia in an exhaust gas stream; and provided that the ammonia oxidation catalyst composition and the substrate are free of Platinum Group Metals. |

1. A system for reducing ammonia (NH3) emissions comprising:
a component comprising a substrate and an ammonia oxidation catalyst disposed thereon, wherein said ammonia oxidation catalyst comprises a small pore molecular sieve supporting a transition metal selected from Cu, Fe, Ce, Mn, Ni, Zn, Ga, Mo, and Cr, wherein said ammonia oxidation catalyst is effective at oxidizing ammonia in an exhaust gas stream; and wherein said component is free of Platinum Group Metals. |
