  • Organoclays
    Patent number: 4743305
    Abstract: An organoclay is prepared by mixing a quaternary ammonium compound with an aqueous suspension of a smectite clay in proportions such that there are present from 75 to 110 milliequivalents of quaternary ammonium cation per 100 g of dry smectite clay, thereafter subjecting the smectite clay/quaternary ammonium compound/water mixture to high shear mixing for a time sufficient to dissipate in the mixture at least 100 KJ of energy per kg. of dry solids in the mixture; and then dewatering the product thus obtained.
    Type: Grant
    Filed: November 12, 1986
    Date of Patent: May 10, 1988
    Assignee: ECC International Limited
    Inventors: Neil T. Doidge, Howard Goodman, Andrew R. Fugler
  • Granule for separating organic compounds from aqueous liquids
    Patent number: 4695511
    Abstract: A granule comprises an inner core, which is formed from a material which does not expand appreciably in the presence of organic compounds, and an outer shell formed from an organo-clay which is preferably held on the inner core with the aid of a binder.The granule can be prepared by tumbling a particle of the inner core material in admixture with a powdered organo-clay and a binder therefor. A particulate bed of the granules can be used for separating organic compounds from a mixture thereof with an aqueous medium.
