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 (g) sufficient to form vapor within the cell and to thus rupture the 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.

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: A method is disclosed for recovering condensed solidified volatile metals from slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed onto the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials are removed and recovered. Finely divided slag particles are separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor is obtained from which the dissolved volatile metals are recovered by electrolysis.

Abstract: A pumpable slurry of shredded scrap solid carbonaceous plastic-containing material that contains associated inorganic matter in admixture with a comminuted aluminosilicate-containing material having noncombustible constituents is reacted by partial oxidation to produce synthesis gas, reducing gas, or fuel gas. The noncombustible constituents in the aluminosilicate-containing material captures the inorganic matter in the scrap solid carbonaceous plastic-containing material while in the reducing atmosphere of the gasifier to produce nontoxic, nonleachable slag. The slurrying medium is water, liquid hydrocarbonaceous fuel, or mixtures thereof. Scrap plastics may be disposed of by the subject process without polluting the nation's environment.

Abstract: A process is claimed for the partial oxidation, in the fly ash mode, of solid, ash-contg. carbonaceous fuels, where an aq. suspension of particulates is obtained by passing the product gas, contg. low-C ash particles and high-C unconverted fuel particles, from the partial oxidation zone through a water-contg. quench chamber. The improvement comprises (a) screening the suspension to remove large particles, (b) sepg. the screened suspension in a continuous centrifuge operating at 10-1000 G into (i) a high-C cake and (ii) a dilute aq. suspension contg. low-C particles, and (c) recycling the high-C cake with fresh feed to the partial oxidation zone. High overall C conversion is obtained and the amt. of waste material to be disposed of is minimised.
