Abstract

Oppfinnelsen vedrører et sinkaluminat som er kjennetegnet ved at det etter kalsinering ved 800°C i 8 timer har et spesifikt overflateareal på minst 85 m/g. Oppfinnelsen vedrører også en forløperblanding av det nevnte aluminat. Fremgangsmåten for fremstilling av aluminatet og blandingen omfatter de -•. følgende - trinn: å. bringe-et "sinksalt, -sol eller -alkoksyd og et aluminiumalkoksyd i kontakt i et løsningsmiddelmedium, å hydrolysere den resulterende blandingen ved å tilsette en mengde vann i overskudd i forhold til aluminiumalkoksydet, å utvinne det dannede presipitatet og eventuelt tørke dette, idet forløperblandingen derved oppnås, om nødvendig å kalsinere det nevnte presipitat, idet aluminatet derved oppnås. Til sist vedrører oppfinnelsen anvendelse av aluminatet for behandling av avgasser fra motorkjøretøyer.
