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.

Raw materials for vanadium-free or vanadium-reduced denox catalysts, and method for producing same

A composition containing titanium and iron compounds, in particular decomposition residue that accumulates as a production residue after the sulphate process during the production of titanium dioxide, is used as an adsorbing agent for inorganic and organic compounds, for example compounds containing phosphorus, arsenic, antimony, sulphur, selenium, tellurium, the cyano group or heavy metal. Toxic substances and pollutants may be removed from a fluid using the adsorbing agent.

Adsorbing agent containing titanium and iron compounds

The invention relates to fine-particulate zirconium titanates or lead zirconium titanates and a method for production thereof by reaction of titanium dioxide particles with a zirconium compound or a lead and zirconium compound. The titanium dioxide particles have a BET surface of more than 50 m/g. The lead zirconium titanates can be used for the production of microelectronic components.
