Abstract (en)

[origin: WO0059630A1] Catalyzed adsorbers for treating motor vehicle exhaust gas comprising a substrate having dispersed thereon a zeolite and an inorganic oxide washcoat, said washcoat having been impregnated with a catalytically effective amount of noble metal prior to being mixed with said zeolite and optionally with a promoter. A method of making such catalyzed adsorbers comprising treating an inorganic oxide with a noble metal reagent, mixing the product with zeolite, coating a substrate, drying and calcining.
