  • Alkali metal-modified vanadium-phosphorus oxide (VPO) catalyst
    Patent number: 9931618
    Abstract: The present invention relates to a catalyst containing a vanadium-phosphorus oxide and an alkali metal, wherein the proportion by weight of alkali metal in the vanadium-phosphorus oxide is in the range from 10 to 400 ppm, based on the total weight of the vanadium-phosphorus oxide, a process for producing it and also the use of the catalyst for the gas-phase oxidation of hydrocarbons, in particular for preparing maleic anhydride.
    Type: Grant
    Filed: March 30, 2015
    Date of Patent: April 3, 2018
    Assignee: Clariant International Ltd.
    Inventors: Thomas Cotter, Andreas Reitzmann, Gerhard Mestl, Gabriele Donabauer, Susanne Roehrer
  • Shaped catalyst body for flow-through fixed-bed reactors
    Patent number: 9409160
    Abstract: The invention relates to a shaped catalyst body for the catalytic conversion of organic and inorganic components in fixed-bed reactors, wherein the shaped catalyst body is formed as cylinder with a base, a cylinder surface, a cylinder axis and at least one continuous opening running parallel to the cylinder axis, and the base of the cylinder has at least four corners.
