  • Patent number: 11857978
    Abstract: A fragmentation system for electrodynamic fragmentation of material contains a feed and an outlet for transporting material along a transport path in a transport direction. At least one high-voltage pulse source is provided, each of the high-voltage pulse sources contains at least one first electrode and at least one second electrode for generating a high-voltage discharge in a discharge chamber. The transport path has a fractionation section, and the fractionation section extends through the discharge chamber. A selection device for selectively extracting the material on the transport path is provided in order to channel material and/or fragments of the material having a diameter smaller than a minimum diameter past at least one portion of one of the fractionation sections.

  • Publication number: 20230219850
    Abstract: The present invention relates to calcium-containing, porous, mineral materials having a sulfate content of not more than 1.5% by weight and a biopolymer content in the range of 0.001 to 5.00% by weight, each relative to the total weight of the materials, a method for producing these materials with the aid of biopolymers as stabilizers and the use of biopolymers for producing sulfate-poor calcium-containing, porous, mineral materials.

  • Publication number: 20220372301
    Abstract: The present invention relates to a process for the processing and/or purification of carbon black comprising the steps of: a) providing carbon black containing impurities b) providing an aqueous fluid comprising a nitrogen hydride c) providing an alkali metal hydroxide and/or an alkali metal d) contacting the mixture of step a), the fluid of step b) and the alkali metal hydroxide and/or alkali metal of step c) e) subjecting the composition obtained in step d) to an elevated temperature in the range of 80 to 240° C. and an elevated pressure in the range of 5 to 50 bar f) separating a carbonaceous solid from the composition obtained in step e). The present invention further relates to the use of a nitrogen hydride as a dispersing agent for producing and/or stabilizing an aqueous suspension.

  • Publication number: 20210319377
    Abstract: The subject matter of the present application relates to a test method for determining the risk potential of an alkali-silica reaction in mineral construction materials such as concrete. The test method may be characterized by the steps of: a) examining (220) a sample (12) by means of Raman spectroscopy for providing a structural characterization (230) of the sample (12), b) comparing (240) the examination result to values (250) stored in a database, and c) using (260) the result of the comparison (240) for ascertaining (270) a risk potential for the concrete for an alkali-silica reaction.
