Abstract

Sammensetning til bruk som NO-felle, basert på mangan og jordalkali eller sjelden jordart, og anvendelse av disse for behandling av eksosgass. Sammensetningen. omfatter en bærer og en aktiv fase, idet den aktive fasen er basert på mangan og i det minste ett annet element A som er valgt blant jordalkalier og sjeldne jordarter, og som kan ha et spesifikt overflateareal på i det minste 10 m/g etter kalsinering i 8 timer ved 800°C. Bæreren kan være på basis av alumina eller alumina stabilisert med silisium, zirkonium, barium eller en sjelden jordart basert på silika eller silika og titanoksyd.Composition for use as a NO-trap, based on manganese and alkaline earth or rare earth, and their use for the treatment of exhaust gas. The composition. comprises a carrier and an active phase, the active phase being based on manganese and at least one other element A selected from alkaline earth and rare earths, and which may have a specific surface area of at least 10 m 2 / g after calcination. for 8 hours at 800 ° C. The support may be based on alumina or alumina stabilized with silicon, zirconium, barium or a rare earth based on silica or silica and titanium oxide.
