Patent ID: 7807605

Claim:
A process for the preparation of a TiO 2 -containing catalyst or catalyst support which is stable to high temperatures, comprising: adding an aqueous Ti-containing solution having dissolved Ti content equivalent to 10 to 250 g TiO 2 per liter of solution to an aqueous suspension of not more than 10 wt. % of a dispersed inorganic support material to form a product mixture; wherein the inorganic support material has a specific surface area, measured by the BET method, of >20 m 2 /g and any agglomerates thereof have a particle size of d 50 <10 μm; wherein the Ti-containing solution is added to said suspension at a rate such that not more than the equivalent of 0.05 g TiO 2 per m 2 of support surface an hour is added and the TiO 2 is precipitated as hydrated titanium oxide on the inorganic support, filtering the product mixture to form a filtered product; washing the filtered product to form a washed product; and calcining the washed product or introducing into an autoclave together with water and kept at temperature of >100° C. for a period of one hour to 5 days the washed product to yield the TiO 2 -containing catalyst or catalyst support.
