  • Patent number: 11465119
    Abstract: The invention relates to a catalyst filling, comprising a first layer of a planar catalyst material and a second layer of a planar catalyst material lying over said first layer, wherein the catalyst material of the first layer comprises at least two plates, which butt against each other to form an abutment edge in each case, wherein the catalyst material of the second layer comprises at least two plates, which butt against each other to form an abutment edge in each case, and wherein the plates of the second layer are designed and/or arranged relative to the plates of the first layer in such a way that the abutment edge or abutment edges of the second layer are not aligned with the abutment edge or abutment edges of the first layer.

  • Publication number: 20200276644
    Abstract: The invention relates to a method for producing open-pore molded metal bodies which have a modified surface. The surface of an open-pore molded metal body said molded body being used as a semi-finished product, is coated with particles of a chemical compound of a metal on particles of the metal which can be reduced or thermally or chemically decomposed in a thermal treatment. After the coating process, at least one thermal treatment is carried out, in which the produced metal particles are connected to the surface of the semi-finished product and/or adjacent produced particles via sintered necks or sintered bridges such that the specific surface area of the obtained open-pore molded body is increased to at least 30 m2/l and/or at least by a factor of 5 in comparison to the starting material of the uncoated metal semi-finished product.

  • Publication number: 20200263306
    Abstract: A method for producing open-pored molded bodies made of a metal. The surface of the metal open-pored molded body being used as a semi-finished product, is coated with particles of the same metal with which the semi-finished product is made or with particles of a chemical compound of the metal the semi-finished product is made, wherein the compound or particles can be reduced or thermally or chemically decomposed in a thermal treatment. After the coating process, a thermal treatment in a suitable atmosphere is carried out, in which the particles are connected to the surface of the semi-finished product and/or adjacent particles such that the specific surface area of the obtained open-pore molded body is increased to at least 30 m2/l and/or at least by a factor of 5 in comparison to the starting material.

  • Patent number: 10596556
    Abstract: A metallic foam body containing an alloy skin which is up to 50 ?m thick can be obtained by a process including (a) providing a metallic foam body comprising a first metallic material; (b) applying a second metallic material which contains a first metallic compound that is leachable as such and/or that can be transformed by alloying into a second metallic compound that is leachable and different from the first metallic compound on a surface of the foam body (a), by coating the metallic foam body with an organic binder and a powder of the second metallic material; (c) forming a skin on foam body (b) by alloying the first and the second metallic material; and (d) leaching out with a leaching agent at least a part of the first and/or the second metallic compound.

  • Patent number: 9505617
    Abstract: Disclosed are a radiating wall catalytic reactor for providing heat from the inside wall surface 8 of a reaction chamber 1 by radiation 16 to support an overall endothermic gas phase chemical reaction taking place in the reaction chamber 1, and a process for carrying out a chemical reaction in the reactor. The reaction chamber 1 is provided with an entrance port 2 for introducing a gaseous reactant(s) in a continuous manner into the chamber 1 and an exit port 3 to enable the gaseous product(s) to leave the chamber 1 in a continuous manner. The reaction chamber 1 includes a plurality of catalyst segments (A)5, which has one void segment (B)6 on either side of it; and the reaction chamber 1 is made of a material(s) that is (are) suitable to resist a temperature of 700° C. or more.
