TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The additive is calcium carbonate, sodium carbonate, sodium hydroxide, calcium salt, hydroxides and/or bicarbonates.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The heat exchanger heats the organic feedstock to a temperature of 55 degrees C and the heater heats the organic feedstock to a temperature of 75 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The step of heating the organic feedstock comprises heating the organic feedstock in a heat exchanger and a heater. The preprocessed organic feedstock is pressurized to a pressure of 100-350 bar and heated to a temperature of 250-400 degrees C. The step of extracting the fuel from the organic feedstock comprises contacting the preprocessed and processed organic feedstock with a solvent. The step of contacting the preprocessed and processed organic feedstock with a solvent comprises contacting the preprocessed and processed organic feedstock with the solvent in a column facilitating countercurrent flow between the preprocessed and processed organic feedstock and solvent. The step of extracting the fuel from the preprocessed and processed organic feedstock comprises at least one separation process comprising distillation, settling, membrane filtration, decantation, centrifugation, ion exchange, drying, evaporation or vacuum distillation. Preferred Components: The solvent is hexane, kerosene, ethylene, propylene, butene-1, ethane, propane, butane, isobutane, pentane, heptane, octane, 2,2-dimethylbutane, 2,3-dimethylbutane, 2,2-dimethylheptane, 2,5-dimethylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane, hexamethylethane, 2-methylbutane, 2-methylhexane, 2-methylpentane, 3-methylpentane, cyclohexane, methylcyclopentane, 1,2,3,4-tetrahydronaphthalene hexene-1, heptene-1, octene-1, nonene-1, decene-1,4-methyl-1-pentene benzene, toluene and/or xylene. EXAMPLE - Kelp seaweed was obtained in a wet freshly harvested form and was used as the raw material to be processed. After draining out all free sea water, the kelp was reduced to a pumpable pulp in a mill. The analysis of dry mass at this stage was 18% dry matter, 0 with the remainder being sea water. The pulp feedstock was then mixed with an additive of calcium carbonate and processed at 320 degrees C at a pressure of 200 bar and with a charge time of 1500 seconds. The raw product stream was a typical sludge that yielded a crude oil after extraction with a solvent.
