Removal NO x from Lean Exhaust Gas by Absorption on Oxi-Anionic Materials

Removal NO x from Lean Exhaust Gas by Absorption on Oxi-Anionic Materials

NOx sorption/desorption capacities of Oxi-Anionic materials were measured under representative exhaust gas mixture conditions at 300 °C, with a NOx trap containing CaO and CuOx impregnated over a commercial γ-Al2O3. These systems absorb (or adsorb) NOx in a gas stream containing both CO2 at 300 °C....

Zusammenfassung:NOx sorption/desorption capacities of Oxi-Anionic materials were measured under representative exhaust gas mixture conditions at 300 °C, with a NOx trap containing CaO and CuOx impregnated over a commercial γ-Al2O3. These systems absorb (or adsorb) NOx in a gas stream containing both CO2 at 300 °C. In the case of a thermal desorption, the trapped NOx should desorb at a temperature below 550 °C.
