An anatase titanium dioxide includes at least one compound selected from oxides of Si, Al, and Zr in an amount of 2-50% b.w., calculated as oxides, of a total weight of the oxides, and a sulfur content of less than 150 ppm based on the total weight of the oxides.

Process for reducing the sulphur content of anatase titania and the so-obtained product

A composition that comprises a titanium compound, an iron compound, and a tungsten compound, wherein the titanium compound has a microcrystalline anatase structure and/or is obtained in the production of TiO2 according to the sulphate process, during hydrolysis of a solution which contains titanyl sulphate, and also in that the composition has a vanadium content, calculated as V, of less than 0.15 wt. % in relation to the solids content of the composition. A catalyst or catalyst raw material containing the claimed composition, as well as to a dimensionally stable and catalytically active solid body can be obtained by mixing the composition defined above with binders, plasticisers and optionally, further additives, molding the obtained composition preferably by extrusion, and subsequently carrying out calcination, or by providing a dimensionally stable and catalytically active solid body that can be obtained by applying the composition, optionally together with binders, plasticisers and further additives, to a substrate, and subsequently carrying out calcination.
