  • Aluminum promoted hydrogenation of alkylation sludge for aluminum chloride recovery
    Patent number: 6004519
    Abstract: The recovery of aluminum chloride from deactivated alkylation catalyst complexes by hydrogenation using hydrogen gas and an aluminum catalyst is disclosed. Using aluminum to catalyze the hydrogenation allows the reaction to proceed at a lower temperature and pressure while reducing the amount of hydrogen chloride present in the reactor thus reducing the corrosiveness and cost of the aluminum chloride recovery. Methods for batch, batchwise continuous, and continuous aluminum chloride recovery are disclosed.
    Type: Grant
    Filed: January 2, 1997
    Date of Patent: December 21, 1999
    Assignee: Kerr-McGee Corporation
    Inventors: Elliott P. Doane, Jim Yuen-Fong Low, Larry G. Sherman, William A. Yuill
  • Pollution-free process for making trialkyl phosphites
    Patent number: 4724056
    Abstract: A pollution-free process for forming trialkyl phosphite by reaction of phosphorus trichloride with alcohol in the presence of a tertiary amine acid acceptor is described in which by-product hydrochloride salt of the acid acceptor is electrolyzed to regenerate the tertiary amine for recycle for further use in reacting additional phosphorus trichloride with alcohol to form additional trialkyl phosphite product.

    Filed: March 5, 1987
    Date of Patent: February 9, 1988
    Assignee: Stauffer Chemical Company
    Inventor: Elliott P. Doane
  • Process for treating liquid chlorinated hydrocarbon wastes containing iron
    Patent number: 4614643
    Abstract: Ferric chloride contained in liquid waste streams comprising higher boiling chlorinated hydrocarbons may be substantially reduced by contacting the waste stream with an amount of water sufficient to convert a substantial amount of the ferric chloride in said stream to solid ferric chloride hexahydrate, and then removing the solid hexahydrate from the waste stream for instance by filtration.

    Inventor: Elliott P. Doane
  • Process for treating liquid chlorinated hydrocarbon wastes containing iron
    Patent number: 4533473
    Abstract: Iron, such as ferric chloride, and other metallic impurities, contained in liquid chlorinated hydrocarbon waste streams, is removed by treatment of such streams with dilute aqueous mineral acid.

  • Oxychlorination of ethylene
    Patent number: 4206180
    Abstract: Oxychlorination of ethylene is carried out using a three-reactor system containing beds of a catalyst comprising a spherical, high-surface area activated alumina impregnated with cupric chloride and potassium chloride. In the first two reactors, the catalyst bed is divided into two sections, with a more active catalyst in the lower section than in the upper. The catalyst is substantially undiluted with inert particles.A new catalyst for such a process is also provided.
