  • Catalyst system based on spherical activated carbon as a carrier and use thereof
    Patent number: 9975109
    Abstract: The invention relates to a method for producing a catalyst system having at least one catalytically active component, wherein the catalytically active component comprises at least one metal, wherein first a spherical activated carbon used as a catalyst carrier is subjected to an oxidation. Subsequently, the catalytically active component is applied, optionally followed by a reduction of the catalyst system obtained in said manner.

  • Adsorbent precipitated on a carrier, method for producing said adsorbent, and use of said adsorbent
    Patent number: 9416028
    Abstract: The invention relates to an adsorbent precipitated on a carrier and to a method for producing said adsorbent. The carrier comprises a polymer-based spherical activated charcoal. The adsorbent comprises an inorganic precipitate capable of adsorbing a metal cation or a mixture of metal cations from a liquid, preferably aqueous, medium. The adsorbent precipitated on a carrier is used to remove, for example, Cs+ from water containing Cs+, in particular from water contaminated with radiotoxic 137Cs+.
