Abstract: A process for disposing of sewage sludge comprising the steps of, (1) dewatering the sewage sludge to produce an aqueous slurry of sewage sludge having a solids content of about 10 to 30 wt. %; (2) simultaneously heating and shearing said dewatered sewage sludge at about 150.degree. F. to 210.degree. F. in the absence of air for 0.5 seconds to 60 minutes while being continuously passed through a tubular-shaped processing means containing a plurality of rotating agitators, thereby producing a pumpable slurry having a viscosity of less than about 2000 centipoise; (3) dewatering the sewage sludge if necessary; (4) mixing at a temperature in the range of about ambient to 180.degree. F. in a ribbon or in-line static mixer the slurry of sewage sludge from (2) and/or (3) with a supplemental solid carbonaceous fuel e.g. coal and/or petroleum-coke to produce a pumpable aqueous slurry of sewage sludge and supplemental fuel having a solids content in the range of about 50 to 60 wt. %; (5) mixing the slurry of sewage sludge and supplemental fuel from (4) in a steam jacketed continuous rotary disc mixer at about 180.degree. F. to 250.degree. F. while removing steam to produce a pumpable slurry of dewatered sewage sludge and solid fuel having a solids content of 50 to 65 wt. % and a HHV of 6,000 to 18,000 BTU/LB; and (6) burning said pumpable slurry from (5) in a partial oxidation gasifier, furnace, boiler, or incinerator to produce an 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.

Abstract: Municipal sanitary sewage sludge is disposed of by an improved partial oxidation process without polluting the environment. Aqueous slurries of sewage sludge are upgraded by hydrothermal treatment, preferably while being sheared, concentrated, and then mixed with a supplemental fuel, preferably coal. A pumpable aqueous slurry of sewage sludge-coal and/or petroleum coke is thereby produced having a greater total solids and heat content (HHV) as well as containing an increased amount of sewage sludge for reacting with free-oxygen containing gas in a free-flow partial oxidation gas generator. Hot quench water or steam produced by cooling the hot raw effluent stream of synthesis gas, reducing gas or fuel gas from the gasifier may provide heat for the hydrothermal step.

Abstract: An apparatus for coating a substrate with an alumina hydrate film includes a coating vessel having at least one support therein; the substrate to be coated is mounted on the support; and at least one porous or perforated container for holding aluminum metal to react with a caustic solution to form an aluminate coating solution is also mounted on the support. The apparatus can also contain means for mechanical agitation, such as a rotational stirring device. In the coating of the substrate a caustic solution is contacted with a substrate and with at least one porous container having aluminum metal therein. The aluminum metal reacts with the caustic solution to form an aluminate coating solution and then an alumina hydrate film is deposited on the substrate. The caustic solution is preferably subjected to mechanical agitation during the coating process.

Abstract: An extruder for feeding finely divided solids. And, in combination therewith, means for using gas in various ways to repulverize the finely divided solids. It lends itself to a procedure for continuously charging finely divided solids with water into a high pressure reactor. The high pressure is inherently contained, and the solids are repulverized for use in a reaction.

Abstract: Filter for treating a gas such as the exhaust gas stream from a diesel engine, which exhaust gas often conveys carbon particles into the atmosphere. The treating filter comprises a casing holding a plurality of serially arranged filter beds. The latter are comprised of monolith ceramic discs, and are maintained in spaced apart relationship by spacer rings to define a turbulation chamber between adjacent beds. Said beds are provided with an oxidation catalyst to promote incineration of the retained particles. The beds further serve to reinforce and support a non-rigid filtering media contained within the respective chambers.
