  • Process for the fixed-bed sweetening of petroleum fractions
    Patent number: 5026474
    Abstract: A process for sweetening a petroleum fraction by catalytic oxidation of mercaptans contained therein in a fixed bed of the supported catalyst, with the oxidation reaction being carried out in the absence of an aqueous phase and in the presence of an oxidizing agent, and the water molecules formed during the oxidation reaction being removed from the catalyst support by washing the latter periodically with a substantial quantity of a polar solvent that is miscible with water.
    Type: Grant
    Filed: December 21, 1989
    Date of Patent: June 25, 1991
    Assignee: Compagnie de Raffinage et de Distribution Total France
    Inventors: Rene Blondeau, Claude Marty, Patrick Ansquer
  • Catalytic composite product for the oxidation of mercaptans and its use for the sweetening of petroleum fractions
    Patent number: 4794097
    Abstract: Composite catalytic products composed of a metal chelate based catalyst on a solid adsorbent support for use in fixed-bed processes for sweetening mercaptans contained in petroleum fractions are disclosed. The composites contain from 0.05 to 5 weight percent of a metal chelate, from 5 to 15 weight percent of pyrolyzed carbon and from 60 to 90 weight percent of a mineral matrix. The support material is obtained by pyrolysis of wash concentrates of raw wools.
