  • Patent number: 11111445
    Abstract: The invention relates to a method of separating and purifying products from a high pressure processing system adapted for processing a feed stream comprising carbonaceous material at a pressure of at least 150 bar and a temperature of at least 300° C., where the converted feed stream (product mixture) is cooled to a temperature in the range 50 to 250° C., and depressurized to a pressure in the range 1 to 150 bar, the method comprising separating the depressurized product mixture in gas phase, an oil phase (liquid hydrocarbon), and a water phase comprising water soluble organics, dissolved salts and optionally suspended particles in a first phase separator and purifying the oil phase from the first phase separator by mixing it with one or more washing agents, at least one of which comprises water, and separating the oil phase from the one or more washing agents in a further separation step.

  • Patent number: 10533138
    Abstract: Products from a high pressure processing system are separated and purified. The processing system is adapted for pressurizing and heating a feed mixture comprising carbonaceous material(-s) in the presence of homogeneous catalysts and liquid organic compounds to produce a converted feed mixture. The converted feed mixture is cooled and depressurized, and then separated into: a gas phase, an oil phase, and a water phase comprising liquid organic compounds and dissolved homogeneous catalysts comprising potassium and/or sodium. The liquid organic compounds and dissolved homogenous catalysts are at least partly recovered from said water phase, thereby producing a first water phase stream enriched in liquid organic compounds and homogeneous catalysts and a second water phase stream depleted in liquid organic compounds and homogeneous catalysts. The first water phase is at least partly recycled to the feed mixture, with a bleed stream being withdrawn therefrom prior to recycling.

  • Publication number: 20190144757
    Abstract: The invention relates to a method of separating and purifying products from a high pressure processing system adapted for processing a feed mixture comprising carbonaceous material(-s) at a pressure of from about 150 bar to about 400 bar and a temperature from about 300° C. to about 430° C. in the presence of homogeneous catalysts in the form of potassium and/or sodium in a concentration of at least 0.5% by weight and liquid organic compounds in a concentration from about 5% to about 40% by weight in a predefined time thereby producing a converted feed mixture, wherein the converted feed mixture is cooled to a temperature in the range 50 to 250° C.
