Abstract: Processes for the preparation of chlorine by catalytic gas phase oxidation of hydrogen chloride with oxygen, wherein the catalyst comprises at least one support substance and at least one catalytic metal sulfide, catalysts which comprise at least one support substance and at least one catalytic metal sulfide, and processes for making the same.

Abstract: Processes are disclosed comprising: (a) providing a gas phase comprising hydrogen chloride and oxygen; and (b) oxidizing the hydrogen chloride with the oxygen in the presence of a catalyst comprising tin dioxide and at least one oxygen-containing ruthenium compound.

Abstract: Processes for the preparation of chlorine by catalytic gas phase oxidation of hydrogen chloride with oxygen, wherein the catalyst comprises tin dioxide and at least one halogen-containing ruthenium compound, and such catalysts comprising at least one halogen-containing ruthenium compound and a tin dioxide support material are disclosed along with the use thereof.

Abstract: Oxidation catalysts which comprise at least one constituent active in the catalysis of oxidation reactions, and a support for said constituent, characterized in that the support includes carbon nanotubes; are disclosed along with processes for their use including the oxidation of hydrogen chloride. Such catalysts can exhibit a higher stability and activity than that of catalysts of the state of the art.

Abstract: The present invention provides a process for producing chlorine by the catalytic gas phase oxidation of hydrogen chloride with oxygen, wherein the reaction is performed on at least two catalyst beds under adiabatic conditions, as well as a reactor system for performing the process.

Abstract: The invention relates to a method for producing highly pure, granular silicon by decomposing a gas containing silicon in a procedure comprising at least two operating states, at least one state comprising the increased formation of nucleus particles from the decomposition of said gas containing silicon and at least one other state comprising the increased separation of the silicon with expansion of the diameter of the silicon granules. The invention also relates to the use of silicon produced in this way and to highly pure, granular silicon particles which are characterised by a coreless structure.
