  • Raw materials for vanadium-free or vanadium-reduced denox catalysts, and method for producing same
    Patent number: 9248433
    Abstract: 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.

  • Supported catalyst of digestion residues of titanyl sulphate-containing black solution
    Patent number: 9211526
    Abstract: A composition includes titanium dioxide-containing digestion residue from titanium dioxide production, and at least one further component which is catalytically active. Dimensionally stable, catalytically active solids which are obtained from this composition can be used as catalyst, for example for minimizing nitrogen oxides.

  • Adsorbing agent containing titanium and iron compounds
    Patent number: 8668888
    Abstract: 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.
