Abstract:
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° C. to 1200° C. for at least 1 hour to obtain a calcined mixed oxide.

Claim (Index 3):
A calcined mixed oxide according to  claim 1 , wherein the calcined mixed oxide comprises:\n cerium from 5% to 50% by weight; aluminium from 40% to 70% by weight; zirconium from 5% to 40% by weight, and rare earth metals (RE) other than cerium from 0.1% to 9% by weight.
