  • Shale oil stabilization with a hydrogen donor quench and a hydrogen transfer catalyst
    Patent number: 4536277
    Abstract: A process is provided to produce and stabilize shale oil. In the process, raw oil shale is retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of oil shale dust. In order to minimize polymerization of the product stream and agglomerate the shale dust, the product stream is stabilized with a hydrogen donor quench in the presence of a hydrogen transfer catalyst upon exiting the retort. The quenched stream is subsequently purged of catalyst, dedusted, and upgraded.
    Type: Grant
    Filed: February 24, 1984
    Date of Patent: August 20, 1985
    Assignee: Standard Oil Company (Indiana)
    Inventors: Thomas M. O'Grady, David F. Tatterson, Ronald Coates

    Abstract: A process is provided to produce and stabilize shale oil. In the process, raw oil shale is retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of oil shale dust. In order to minimize polymerization of the product stream and enhance agglomeration of the shale dust, the product stream is stabilized with a hydrogen donor quench upon exiting the retort. The quenched stream is subsequently dedusted and upgraded.

  • Active carbon process and composition
    Patent number: 4082694
    Abstract: An improved process is disclosed whereby coal, coke or a combination thereof can be converted in good yield to a very high surface area active carbon with a unique and useful combination of properties, which carbons are particularly useful for water purification. Novel active carbons having a very high surface area which substantially have a cage-like structure exhibiting microporosity are disclosed.
