Abstract

Oppfinnelsen vedrører en understøttet katalysator og en fremgangsmåte for fremstilling av denne. Den understøttede katalysator i samsvar med oppfinnelsen er særlig nyttig ved behandling av avgasser fra interne forbrenningsmotorer og omfatter en porøs bærer hvorpå det er avsatt katalytisk aktive elementer og særlig cerium assosiert med andre elementer. Cerium avsettes i henhold til oppfinnelsen bare på en perifer krans med bredde bestemt av bæreren ved impregnering med en kolloidal oppløsning av en ceriumforbindelse.The invention relates to a supported catalyst and to a process for its preparation. The supported catalyst according to the invention is particularly useful in the treatment of exhaust gases from internal combustion engines and comprises a porous support onto which catalytically active elements and especially cerium associated with other elements are deposited. According to the invention, cerium is deposited only on a circumferential rim of the carrier determined by impregnation with a colloidal solution of a cerium compound.
