Abstract: In the operation of smoking/burning type volume reduction treatment apparatus (1), referring to view (A), charcoal carbonized layer (T2) is spread over powdery ceramic layer (T1) in the state of having negative ion air fed through air supply inlet (H). Further, sawdust layer (T3) is spread thereover, and thereafter treatment subject layer (V) is piled thereon. In a temporary burning region of the carbonized layer (T2), the powdery ceramic layer (T1) exerts not only heat storing action but also heat radiation action. Referring to view (B), the interior of the sawdust layer (T3) is altered into temporary carbonized layer (T3 1) and temporary dried layer (T3 2). As the temporary burning region slowly moves upward, an under side of the treatment subject layer (V) is altered into dried layer (V1) and further, carbonized layer (V2) shown in view (C) is formed. Thereafter, this carbonized layer (V2) catches fire, so that burning region (V3) is formed in layered form in the treatment subject layer (V).

Abstract: Systems and methods for recycling waste and reclaiming beneficial and useful compositions such as organic solvents comprises a shredder, operating in an inerted or anaerobic atmosphere, which shreds the waste into smaller pieces that are fed into and indirectly heated in an anaerobic desorption unit so as to vaporize at least one organic compound associated with the waste. A vacuum means is used to transfer the organic compound vapors from the desorption unit to a water quench condensing unit that operates to produce a mixed organic compound liquid stream. The liquid organic compound and water stream is then processed in an oil and water separator. The water is separated and can be reused in the system for quenching gas vapors or inerting the desorption unit. The water-free mixed organic compound liquid stream is then fed into a multi-stage packed distillation column separating organic compound according to boiling points to produce products such as organic solvents.
Abstract: A connector for a pressure vessel includes a connector assembly having a first plurality of contacts, and a receiver assembly configured to be positioned within a receiver aperture formed in a closure of the pressure vessel and having a second plurality of contacts. The receiver assembly is configured to receive the connector assembly and place each of the first plurality of contacts in electrical contact with a corresponding one of the second plurality of contacts. A seal is provided between the connector assembly and the wall of the pressure vessel, for substantially sealing the receiver aperture from pressure within the vessel. The connector assembly is configured to be coupled to a product carrier, and sensors positioned in the vessel are coupled via the connector assembly to a data acquisition unit. When the closure is lowered onto the vessel, the receiver assembly contacts the connector assembly coupled to the carrier, closing the electrical contacts connecting the sensors to the acquisition unit.

Abstract: The present invention is a chemical reactor and method for catalytic chemical reactions having gas phase reactants. The chemical reactor has reactor microchannels for flow of at least one reactant and at least one product, and a catalyst material wherein the at least one reactant contacts the catalyst material and reacts to form the at least one product. The improvement, according to the present invention is: the catalyst material is on a porous material having a porosity that resists bulk flow therethrough and permits molecular diffusion therein. The porous material further has a length, a width and a thickness, the porous material defining at least a portion of one wall of a bulk flow path through which the at least one reactant passes.

Abstract: A system for substantially continuously providing a solid material, for example pulverized coal, to a pressurized container. The system provides the solid material to a first container of a first pressure elevated above an initial pressure of the solid material. Generally, a screw conveyor augmented with a jet port is used to move the material where the jet port provides a gas to provide a make-up volume of the solid material. The system also provides the material to a second high pressure container after the material has been formed into a slurry. Therefore, the solid material may be substantially continuously provided in a system to a high pressure container.
