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.The invention relates to a zinc aluminate which is characterized in that after calcination at 800 ° C for 8 hours it has a specific surface area of at least 85 m 2 / g. The invention also relates to a precursor mixture of said aluminate. The process for preparing the aluminate and the mixture comprises the - •. the following steps: contacting a zinc salt, sol or alkoxide and an aluminum alkoxide in a solvent medium, hydrolyzing the resulting mixture by adding an excess amount of water to the aluminum alkoxide, recovering the precipitate formed and optionally drying this, the precursor mixture being thereby obtained, if necessary calcining the said precipitate, thereby obtaining the aluminate Finally, the invention relates to the use of the aluminate for the treatment of exhaust gases from motor vehicles.
