摘要： A process for disposing of sanitary sewage sludge by producing a pumpable slurry of sewage sludge with or without solid carbonaceous fuel and burning said slurry as fuel in a partial oxidation gas generator, furnace, or boiler. First, an aqueous slurry of sewage sludge is concentrated to produce sewage sludge cake. The sewage sludge cake is preheated and sheared while in contact with sulfuric or sulfurous acid to produce a pumpable acidified aqueous slurry of sewage sludge having a pH of about 1 to 5. After two-stage hydrothermal treatment with neutralization of the sewage sludge after the second hydrothermal stage, the solids content of the pumpable aqueous slurry of sewage sludge is increased. By means of the subject process, the viscosity of the slurry of sewage sludge with or without solid carbonaceous fuel is reduced and coagulation is suppressed. A pumpable aqueous slurry of sewage sludge with or without solid carbonaceous fuel is produced and burned with a free-oxygen containing gas in a partial oxidation gasifier, furnace, boiler, or incinerator to produce a hot raw effluent gas stream. In a preferred embodiment, the effluent gas stream is cleaned and purified and non-contaminating ash and slag are separated. By this process, noxious sewage sludge may be disposed of without contaminating the environment. By-product synthesis gas, reducing gas, or fuel gas may be produced.

摘要： A process for disposing of sanitary sewage sludge by producing a pumpable slurry of sewage sludge with or without solid carbonaceous fuel and burning said slurry as fuel in a partial oxidation gas generator, furnace, or boiler. The aqueous slurry of sewage sludge is concentrated by removing water by means of a conventional belt filter press, centrifuge, or hydroclone. The dewatered slurry of sewage sludge is preheated and sheared; hydrothermally treated; and its solids content increased. A chelating agent, for example an aminopolycarboxylic acid or a hydrocarboxylic acid is mixed with the aqueous slurry of sewage sludge during the preheating and shearing step and/or the step for increasing its solids content. By means of the subject process, the viscosity of the slurry of sewage sludge with or without solid carbonaceous fuel is reduced and coagulation is suppressed. A pumpable aqueous slurry of sewage sludge with or without solid carbonaceous fuel is produced and burned with a free-oxygen containing gas in a partial oxidation gasifier, furnace, boiler, or incinerator to produce a hot raw effluent gas stream. In a preferred embodiment, the effluent gas stream is cleaned and purified and non-contaminating ash and slag are separated. By this process, noxious sewage sludge may be disposed of without contaminating the environment. By-product synthesis gas, reducing gas, or fuel gas may be produced.

摘要： A process for converting scrap plastic material into a high quality transportation fuel. The plastic material is granulated and mixed with granulated solid carbonaceous fuel e.g. coal and liquid hydrocarbonaceous solvent e.g. waste motor oil to produce a plastic-containing sludge. The plastic-containing sludge is liquefied in a closed autoclave while in contact with hydrogen gas. A pumpable slurry from the autoclave is heated and fractionated in a fractionation zone to produce a hydrocarbonaceous distillate which may be used for transportation fuel. A bottoms stream from the fractionation zone comprising liquid hydrocarbonaceous material and inorganic material is reacted by partial oxidation to produce nontoxic slag and raw synthesis gas, fuel gas or reducing gas which may be purified in a gas purification zone.

摘要： A process for disposing of sewage sludge by heating and shearing an aqueous mixture of sewage sludge in a tubular-shaped processing means containing a plurality of rotating agitators to produce a pumpable aqueous slurry of sewage sludge. The aqueous slurry of sewage sludge is mixed with solid carbonaceous fuel or an aqueous slurry of solid carbonaceous fuel to produce a pumpable aqueous slurry of sewage sludge and solid carbonaceous fuel. The aqueous slurry of sewage sludge and solid carbonaceous fuel is heated in a first steam jacketed rotary disc mixing-heating means. Alternately, first and second hoppers are filled with said heated aqueous slurry of sewage sludge and solid carbonaceous fuel and cycled between a second steam jacketed rotary disc mixing-heating means; wherein while one hopper is being filled the contents in the other hopper are being dewatered. The thickened pumpable slurry is burned in a partial oxidation gasifier, furnace, boiler, or incinerator to produce a hot effluent gas steam. By this process, noxious sewage sludge may be disposed of without contaminating the environment. By-product synthesis gas, reducing gas, or fuel gas may be produced.

摘要： A process for disposing of sewage sludge comprising the steps of, (1) dewatering the sewage sludge to produce amorphous sewage sludge having a solids content of about 28 to 50 wt. %; (2) heating said amorphous sewage sludge at about 150.degree. F. to 510.degree. F. in the absence of air for 3 seconds to 60 minutes and mildly shearing the sewage sludge, thereby producing a pumpable feed slurry of sewage sludge having a viscosity in the range of about 400 to 1500 centipoise and a higher heating value in the range of about 5000 to 9500 BTU/LB; and (3) burning said pumpable slurry from (2) in a partial oxidation gasifier, furnace, boiler, or incinerator to produce an effluent gas stream. In one embodiment, the effluent gas stream is cleaned and purified and non-contaminating fly-ash and slag are separated. The fly-ash may be mixed with the sewage sludge in the process to facilitate separation of water during pressing and to encapsulate the non-combustible materials in the sewage sludge. The encapsulated material will flow from the reaction zone as substantially inert molten slag. By this process, noxious sewage sludge may be disposed of without contaminating the environment.

摘要： A process for disposing of sanitary sewage sludge by producing a pumpable slurry of sewage sludge and low grade solid carbonaceous fuel and burning said slurry as fuel in a partial oxidation gas generator, furnace, or boiler. The aqueous slurry of sewage sludge is concentrated by removing water by means of a conventional belt filter press or presses. Prior to and/or immediately after said concentrating step particles of low grade solid carbonaceous fuel e.g. lignitic coal, peat, wood and cellulose-containing materials are mixed with the slurry of sewage sludge. The dewatered slurry of sewage sludge and low grade solid carbonaceous fuel is hydrothermally treated in three stages and excess water is separated by flash evaporization and/or centrifuging. The viscosity of the slurry of sewage sludge and low grade solid carbonaceous fuel is reduced to less than about 2000 centipoise by shearing to produce a pumpable slurry which is burned with a free-oxygen containing gas in a partial oxidation gasifier, furnace, boiler, or incinerator to produce a hot raw effluent gas stream. In a preferred embodiment, the effluent gas stream is cleaned and purified and non-contaminating ash and slag are separated. By this process, noxious sewage sludge may be disposed of without contaminating the environment. By-product synthesis gas, reducing gas, or fuel gas may be produced.

摘要： 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.
