Abstract
Przedmiotem zgłoszenia jest katalizator, który jest układem mieszanych tlenków Cu-Zn-Al modyfikowanych La i/lub Zr w ilości łącznie do 5% masy katalizatora, przy czym La i Zr są rozproszone w całej objętości materiału Cu-Zn-Al-La/Zr. Prekursor katalizatora jest układem hydroksywęglanów co najmniej trzech metali tj. Cu, Zn, Al i ewentualnie cyrkonu i/lub lantanu z dominującym udziałem krystalicznej fazy będącej analogiem hydrotalkitu, w którym stosunek molowy Cu/Zn mieści się w zakresie od 1,5 do 3,0, korzystnie od 1,8 do 2,5, zawierającego związki La i/lub Zr o sumarycznym udziale do 8% korzystnie do 5% wag., w przeliczeniu na tlenki. Zgłoszenie obejmuje też sposób wytwarzania powyższego katalizatora w sposobie wg wynalazku miesza się wodny roztwór glinianowęglanu sodu i/lub potasu i/lub amonu z kwaśnym wodnym roztworem rozpuszczalnych soli miedzi, cynku i ewentualnie cyrkonu i/lub lantanu i ewentualnie wodnym roztworem azotanu tetraaminamiedzi(II), a wytrącona w wyniku zmieszania nierozpuszczalną sól będąca złożonym hydroksywęglanem Cu-Zn-Al-La/Zr, stanowiącą prekursor katalizatora, poddaje się kolejno starzeniu w macierzystej zawiesinie, filtracji, odmywaniu zawiesiny prekursora, suszeniu, formowaniu wstępnemu, kalcynacji, uzyskując prekatalizator, który rozdrabnia się i ponownie formuje w kształtki, i ewentualnie poddaje się impregnacji wodnym roztworem węglanu cezu i/lub potasu, po czym suszy, uzyskując finalny katalizator.
