Abstract: The invention relates to a method for recovering chlorine from hydrogen chloride generated in carbochlorination processes. Further, the invention refers to the use of this method for recovering chlorine from hydrogen chloride generated in a carbochlorination process.

Abstract: The invention relates to a method for treating a residue obtained from the chloride process, wherein the residue comprises the components titanium dioxide, coke, an inert metal oxide, and an iron-containing component. Further, the invention refers to the use of this method to separate the components contained in said residue, and to the use of the separated components in the chloride process for obtaining titanium dioxide.

Abstract: The invention relates to a pigment particle possessing at least one security feature, a method for obtaining the same, and a suspension comprised of the pigment particle. In addition, the invention refers to a method for marking a product with a pigment particle according to the invention and the use of a pigment particle for marking and verifying said pigment particle.

Abstract: The invention is related to a method and vibratory apparatus for the improved solid-liquid filtration of filter cakes, especially for dewatering finely divided thixotropic filter cakes, with the aid of a vibratory apparatus. Further, the invention relates to a filtration apparatus having a vibratory apparatus as described herein, and to the use of the vibratory apparatus for the solid-liquid filtration of filter cakes.

Abstract: The invention relates to a method for separating valuable metal chlorides, particularly titanium tetrachloride and niobium pentachloride, from solid residues, in particular the filter dust generated during the chlorination of raw materials containing iron and titanium in the production of titanium dioxide using the chloride process.

Abstract: The invention relates to a method for the further processing of iron sulfate heptahydrate into iron sulfate monohydrate. An aqueous solution or suspension of iron sulfate heptahydrate is formed and heated in a pressure vessel to a temperature above its boiling temperature at atmospheric pressure and where solid iron sulfate monohydrate and a solution are formed. The solid iron sulfate monohydrate is separated from the solution and fed into a pressure vessel at a temperature above the boiling temperature of the solution at the pressure in the pressure vessel, which is lower than the pressure during separation.

Abstract: A process for rendering an oxygen-sensitive heterogeneous catalyst (s-cat) inert to oxygen, as well as a heterogeneous catalyst that is not sensitive to oxygen, is disclosed. The surface of the s-cat is wetted with an ionic liquid. The ionic liquid firmly adhering to the surface of the catalyst forms a film, which protects the s-cat from reactions with oxygen.
