  • Off-site treatment for hydrogenation catalysts
    Patent number: 7713905
    Abstract: The present invention concerns a process for “ex situ” treatment of a hydrogenation catalyst containing nickel prior to use, consisting of carrying out three steps, namely bringing the catalyst into contact with at least one sulphur-containing compound or agent (the step termed selectivation), treating said catalyst with hydrogen at a temperature of more than 250° C. (the step termed reduction) and passivation of said catalyst.
    Type: Grant
    Filed: April 28, 2004
    Date of Patent: May 11, 2010
    Assignee: Eurecat S.A.
    Inventors: Pierre Dufresne, Franck Labruyere, François Locatelli
  • Regeneration method of heterogeneous catalysts and adsorbents
    Patent number: 7368409
    Abstract: A process for regenerating a palladium catalyst from a catalytic reaction where the catalyst is contaminated with at least carbon. The regenerating is conducted prior to any heating step under oxidizing conditions in the regenerating section. The regenerating involves at least one heating step under a hydrogen-containing reducing atmosphere and under conditions sufficient to lower the content of carbon in the palladium catalyst.

  • Regeneration method of heterogeneous catalysts and adsorbents
    Publication number: 20040043890
    Abstract: Process for the regeneration of a solid catalyst or of a solid adsorbent wherein the catalyst or the adsorbent is used in the form of a bed in a regeneration zone, in which bed the catalyst is in motion, said process comprising at least one heating step under a reductive atmosphere.
