NOVELTY - Mobile thermal treatment system comprises mobile support structure, slurrying device that produces slurry from the feedstock, a pump that pressurizes the slurry to a pressure above the saturation pressure of water at a subsequent elevated temperature, a thermal input device coupled to the mobile support structure and heats the pressurized slurry to the elevated temperature sufficient for lysis of cell and char formation, and reaction device coupled to mobile support structure and provides retention time to thermally treat heated slurry at the elevated temperature.    USE - The mobile thermal treatment system is useful for processing a feedstock including organic material and water. The dewatered sludge cake (obtained as by product) is used as fertilizer or a renewable fuel (all claimed).    DETAILED DESCRIPTION - Mobile thermal treatment system comprises (a) a mobile support structure, a slurrying device that produces slurry from the feedstock, where the slurry has solids content of 16% or less, a pump that pressurizes the slurry to a pressure above the saturation pressure of water at a subsequent elevated temperature, a thermal input device coupled to the mobile support structure and heats the pressurized slurry to the elevated temperature sufficient for lysis of cell and char formation, and a reaction device coupled to the mobile support structure and provides a retention time to thermally treat the heated slurry at the elevated temperature, or (b) a mobile support structure, a slurrying device that produces a slurry from the feedstock, a first pump that pressurizes the slurry to a first pressure above the saturation pressure of water at a first elevated temperature, a first thermal input device coupled to the mobile support structure downstream of the first pump and heats the pressurized slurry to the first elevated temperature, a second pump coupled to the mobile structure downstream of the first thermal input device and pressurizes the heated slurry to a second pressure above the saturation pressure of water at a second elevated temperature, a second thermal input device coupled to the mobile support structure downstream of the second pump and heats the pressurized slurry to the second elevated temperature sufficient for lysis of cell and char formation, and a reaction device coupled to the mobile support structure and provides a retention time to thermally treat the heated slurry at the second elevated temperature.
