ALUMINA-BASED CATALYST SUPPORT WITH A HIGH SPECIFIC SURFACE, PROCESS FOR PREPARING THE SAME AND CATALYST USING THE SAME

摘要

The subject of the invention is a thermally stable alumina-based catalyst support having a high specific surface area, consisting of active alumina granules coated with a hydrated cerium oxide. BR/ This support is prepared by precipitation of cerium hydroxide from an aqueous suspension of alumina granules also containing a soluble salt of cerium. BR/ Application to catalysts used for the treatment of motor vehicle exhaust gases. BR/ (CF DRAWING IN BOPI) BR/ BR/
