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., and depressurized to a pressure in the range 1 to 150 bar, and where the converted feed mixture is separated in to a gas phase comprising carbon dioxide, hydrogen, and methane, an oil phase comprising oil phase liquid organic compounds, and a water phase comprising water phase liquid organic compounds, dissolved salts and optionally suspended particles, where the water phase liquid organic compounds and dissolved homogenous catalysts in the form of potassium and/or sodium are at least partly recovered from said water phase thereby producing a first water phase stream enriched in water phase liquid organic compounds and homogeneous catalysts in the form of potassium and sodium, and a second water phase stream depleted in water phase liquid organic compounds and homogeneous catalysts in the form of potassium and sodium, where the first water phase is at least partly recycled to said the feed mixture to provide at least part of said liquid organic compounds and homogeneous catalysts in the feed mixture, and where further a bleed stream is withdrawn from said water phase enriched in water phase liquid organic compounds and homogeneous catalysts in the form of potassium and sodium prior to recycling said first recycle stream to the feed mixture.
