Abstract: A process for upgrading plastic material containing inorganic filler or reinforcement material for use as feedstock in a partial oxidation gas generator for the production of raw synthesis gas, fuel gas, or reducing gas. The plastic material is granulated and partially liquefied by heating in a closed autoclave at a temperature in the range of about 400.degree. F. to 495.degree. F. and a pressure in the range of about 150 psig to 750 psig while the plastic material is in contact with a pumpable hydrocarbonaceous liquid solvent. A pumpable slurry is thereby produced comprising solubilized plastic, unsolubilized plastic, hydrocarbonaceous liquid solvent, separated inorganic material and unseparated inorganic material. After removing the separated inorganic material, the remainder of the slurry is then reacted by partial oxidation to produce said raw synthesis gas, fuel gas or reducing gas.

Abstract: Pumpable aqueous slurries of low rank coal e.g. subbituminous coal and lignite having a comparatively high solids content are made by keeping the particles of coal in contact with a non-oxidizing gas e.g. nitrogen and/or CO.sub.2 thereby maintaining a hydrophobic surface on the particles of coal while they are ground and dried, contacted with an aqueous slurry of liquid hydrocarbonaceous fuel which is absorbed and which coats the particles of coal, and then dried. The dried coated particles of low rank coal are mixed with water to produce a pumpable slurry having a solids content in the range of about 50 to 60 wt. %. In one embodiment, at least a portion of the water needed to produce said pumpable slurry is derived by cooling and condensing out water from the non-oxidizing gas that was used to dry the low rank coal. In still another embodiment, the dewatered non-oxidizing gas is introduced into the combustor of a gas turbine to moderate the temperature and thereby reduce the formation of NO.sub.x gases.

Abstract: A partial oxidation process and a novel burner are provided for simultaneously introducing two or three separate feedstreams into a free-flow partial oxidation gas generator for the production of synthesis gas and fuel gas, or reducing gas. The reactant feedstreams include a liquid hydrocarbonaceous fuel or a pumpable slurry of solid carbonaceous fuel, and a free-oxygen containing gas e.g. air or oxygen. The burner comprises a central conduit and a plurality of spaced concentric coaxial conduits with down-flowing annular passages. A flat annular-shaped disc or cup-shaped porous ceramic or porous metal cooling means of uniform composition, wall thickness and porosity with the various pores interconnecting is attached to the downstream tip of the burner. A controlled amount of liquid coolant under pressure is passed successively through the porous inside surface, porous core and porous outside surface of the cooling means is vaporized. The tip of the burner is thereby cooled. Stress cracking of the burner tip is prevented; and the life of the burner is extended. Further, deposition of ash on the face of the burner is prevented.

Abstract: An improved process for the low-cost disposal of noxious sewage sludge in a safe way without polluting the environment. In the process, sewage sludge having a solids content of about 0.5 to 20 wt.% is concentrated by pressing in a belt filter press, optionally followed by pressing in a high intensity press. It was unexpectedly found that the morphology of the resulting dewatered sewage sludge is changed by such mechanical treatment so that slurries with higher concentrations of solids are achieved. The dewatered sewage sludge is heated, flash evaporated and/or centrifuged, and mixed with a supplemental fuel e.g., liquid hydrocarbonaceous and/or solid carbonaceous fuel to produce a pumpable fuel slurry having a total solids content in the range of about 50 to 70 wt.% and comprising about 10 to 40 wt.% dewatered sewage sludge and having a higher heating value in the range of about 5,000 to 14,000 BTU/Lb. The fuel slurry may be reacted by partial oxidation in a conventional gasifier to produce synthesis gas and/or fuel gas. The thermal energy in hot byproduct steam and flue gas streams are used to heat the dewatered sewage sludge. In one embodiment, the pumpable slurry of dewatered sewage sludge and supplemental fuel is burned by complete combustion in a furnace or incinerator for the production of steam.

Abstract: This invention relates to a novel pumpable sewage sludge fuel and process for burning it. An aqueous slurry of sewage sludge is dewatered and dried to a solids content in the range of about 50 to 99 wt. % in a drying zone in the absence of free-oxygen containing gas but while in contact with a gaseous material selected from the group consisting of N.sub.2, CO.sub.2, H.sub.2, CO, and mixtures thereof. The dried sewage sludge is mixed with a supplementary fuel from the group consisting of solid carbonaceous fuel, liquid hydrocarbonaceous fuel, mixtures thereof, and optionally with water to produce a pumpable slurry fuel feedstream having a solids content in the range of about 50 to 65 wt. % and a higher heating value of at least about 6,000 Btu/lb. The slurry fuel feedstream may be burned in a partial oxidation gasifier, furnace, boiler, or incinerator.
