Removal NOx from Lean Exhaust Gas by Absorption on Oxi-Anionic Materials

NO x sorption/desorption capacities of Oxi-Anionic materials were measured under representative exhaust gas mixture conditions at 300 °C, with a NO x trap containing CaO and CuO x impregnated over a commercial γ-Al 2 O 3 . These systems absorb (or adsorb) NO x in a gas stream containing both CO 2 at...

Beschreibung
Zusammenfassung:	NO x sorption/desorption capacities of Oxi-Anionic materials were measured under representative exhaust gas mixture conditions at 300 °C, with a NO x trap containing CaO and CuO x impregnated over a commercial γ-Al 2 O 3 . These systems absorb (or adsorb) NO x in a gas stream containing both CO 2 at 300 °C. In the case of a thermal desorption, the trapped NO x should desorb at a temperature below 550 °C.
