A process for the preparation of a calcined mixed oxide comprising Al-, Ce- and Zr-oxides, comprising the steps of providing an aqueous slurry comprising hydroxides of cerium and zirconium, contacting the hydroxides of cerium and zirconium with an alumina precursor to obtain an aqueous suspension of solids, isolating the solids from the aqueous suspension and drying to obtain a solid composition, calcining the solid composition of step (c) at a temperature from 450&#xb0; C. to 1200&#xb0; C. for at least 1 hour to obtain a calcined mixed oxide.

Ceria zirconia alumina composition with enhanced thermal stability

The present invention relates to a process for preparing TiO/SiOmixed oxides or the hydrates and/or oxide hydrates thereof comprised of 0.5 to 95 wt % SiOand the balance as TiO, each referring to the completely calcined product, by using titanium alcoholates and aqueous silica sol. Moreover, the invention relates to the use of these mixed oxides as catalyst carriers.
