  • Apparatus for endothermic reactions of organic compounds
    Patent number: 6872364
    Abstract: An apparatus for conducting an endothermic reaction of an organic' compound in the presence of molecular hydrogen and of multicomponent solids is described. The process of operating the apparatus comprises contacting the compound with a solid catalyst for the endothermic reaction and a hydrogen oxidizing solid reagent intermixed with the solid catalyst. Organic products of the endothermic reaction are produced, with evolution of molecular hydrogen. The solid catalyst becomes gradually deactivated by formation of carbonaceous deposits thereon. The evolved hydrogen undergoes an exothermic reaction with the hydrogen oxidizing solid reagent to form a reduction product which comprises deactivated hydrogen oxidizing solid reagent.
    Type: Grant
    Filed: December 30, 2002
    Date of Patent: March 29, 2005
    Assignee: Sunoco, Inc. (R&M)
    Inventors: Thomas W. Bierl, Vincent A. Durante, Lawrence H. Finkel, Daniel E. Resasco

  • Separation of diisopropylether from hydrocarbon streams
    Patent number: 4469491
    Abstract: A process for the separation of diisopropylether from a hydrocarbon stream containing it, by contacting the stream with ethylene glycol whereby the diisopropylether is absorbed by the glycol and a purified hydrocarbon stream is separated therefrom.
