    Abstract: The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge at a temperature sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure sufficient to form vapor within the cell and to thus rupture the weakened cell walls and thereby release the intracellular water in the form of a hot aqueous vapor and/or released intracellular water. The water-reduced concentrated biosludge can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.

    Abstract: In the present invention there is disclosed a process for disposing of scrap plastic and/or waste material comprising: (1) mixing together (a) solid carbonaceous plastic-containing material that contains associated inorganic matter, shredded to particle size to 6.3 mm and comprising at least one material selected from the group consisting of titania, talc, clays, alumina, glass, barium sulfate, and barium carbonate; compounds of Sn, Co, Mn, Pb, Cd, Cr, Cu, B; and steel, nickel, aluminum, brass and copper metal; (b) aluminosilicate-containing material having noncombustible constituents that have an ash fusion temperature in a reducing atmosphere of less than about 1316 degC; wherein said aluminosilicate containing material is selected from the group consisting of coal, coal mine tailings, coal ash, illite clay, volcanic ash, and mixtures thereof; and wherein said aluminosilicate-containing material has a maximum particle size 1.70 mm; a weight ratio of noncombustible constituents in said aluminosilicate-containing material to the inorganic matter in said solid carbonaceous plastic-containing material of at least 1 to 1; and a mole ratio SiO2/Al2O3 in the range of about 1.5 : 1 to 20 : 1; and (c) a liquid slurrying medium selected from the group consisting of water, liquid hydrocarbonaceous fuel, and mixtures thereof; and (2) reacting said pumpable slurry from the step (1) having a minimum HHV of about 10.5 MJ/Kg of slurry with a free-oxygen containing gas to produce synthesis gas, reducing gas, or fuel gas.

    Abstract: The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge (2) at a temperature (4) sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure (8) sufficient to form vapor within the cell and to thus rupture th e weakened cell walls and thereby release the intracellular water. The water- reduced concentrated biosludge (24) can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.
