  • METHOD OF OIL PURIFICATION, AND USES THEREOF FOR FOOD AND FEED
    Publication number: 20100129518
    Abstract: The current invention describes a new process of purifying oils. In particular, the present invention relates to a method which combines treatment with ad- or absorbing agents (AAs) and a membrane-based process for separating the oil from the contaminated AAs. Further, the present invention relates to the use of active carbon and membrane filtration for purifying oil and the use of purified oil as food or feed ingredients.

  • Wet oxidation with the aid of a porous catalytic contactor
    Patent number: 7399414
    Abstract: A process for oxidation of oxidizable materials which are dissolved or suspended in a liquid phase. A contactor in the form of a porous membrane is used. The contactor is designed such that an oxidizing phase flows along one surface thereof while the phase to be oxidized flows along another surface. The oxidation is catalyzed by (i) a catalyst material which constitutes the porous membrane or is deposited in or onto a porous membrane support, or (ii) a catalyst material which is supplied to one or both of the feed streams comprising the oxidizing phase and the phase to be oxidized.
