  • Method and device for producing shell catalysts
    Patent number: 9737886
    Abstract: Disclosed herein is a process and an apparatus for producing coated catalysts. A process of the present disclosure includes providing a composition containing a liquid and a catalytically active material and/or a precursor thereof in a stock vessel, providing a support material in a vessel which is rotatable about a longitudinal axis, transporting the composition from the stock vessel through a first conduit to a spray nozzle, transporting a propellant fluid through a second conduit to the spray nozzle, atomizing the composition and propellant fluid in the nozzle to produce an aerosol that flows into the vessel and impregnates the support material present therein, heating the vessel so the liquid present in the aerosol evaporates from the support material and the finely divided support material which has been treated with catalytically active material and/or a precursor thereof is dried, and discharging the vaporized liquid from the vessel.
    Type: Grant
    Filed: April 15, 2014
    Date of Patent: August 22, 2017
    Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AG
    Inventors: Oliver Noll, Guido Walther, Sigrid Evert, Andreas Martin
