Abstract: A shear retort mill for slow ablative pyrolysis features friction heating between shearing surfaces on a rotating disk and a static or rotating cylindrical drum enclosing the disk. A feed enters the workspace between the rotating disk and the bottom of the drum through a hollow feed shaft coupled to the rotating disk. Preferably, an auger compacts and moves the feed downward, and a shredder reduces the feed's particle size. The feed is increasingly ground and pyrolyzed as it is forced between the drum and disk shearing surface. As the dense processed material extrudes at the edge of the workspace, the gases and liquid products are forced inward by the barrier of dense solids. A static exhaust pipe at the center of the rotating feed shaft allows for the exit of these gases, which preferably go to a heat exchanger to recover any condensable fractions.

Abstract: A mixing system and method may be used to facilitate mixture of ingredients within a container such as a bottle for mixing fitness and recreational beverages and the like. The mixing system may include a mixing apparatus with a container engagement component that couples the mixing system to the container, and a mixing component that mixes the ingredients. The mixing component may have a shaft, a plurality of rotatable mixing members that are rotatable about the shaft, and a plurality of stationary mixing members that are fixedly secured to the shaft. The mixing members may be arranged to contact the ingredients in a manner that facilitates mixture of the ingredients together, in response to repetitive motion of the container.

Abstract: An apparatus and methods of using the apparatus are described to decompose plastic to form a fuel for use in generating energy such as electricity.

Abstract: A method and apparatus for continuously carbonizing materials while co-producing gases in a coking chamber closed to the atmosphere, having a charger at one end comprising a pushing ram surrounding a mandrel that surrounds an air or oxygen injection lance. The other end of the coking chamber collects and separates coke from gases, with coke directed to a closed quenching chamber and gases directed to a cleanup. Thermal energy for converting coal into coke derives from combusting some metallurgical coal by said lance.

Abstract: A system for refining hydrocarbon containing materials in a continuous coking mode may provide a pyrolyzer (1) which may be inclined to effect a liquid seal between a liquid conduction environment (6) and a gaseous conduction environment (7). A heat source (9) may heat the material past the coking point and the system may include a screw or auger (10) which can continuously remove the coke while simultaneously outputting refined products.

Abstract: A distillation system is provided for batch thermolytic distillation of lump carbonaceous material, such as lump wood and shredded rubber tires. The system preferably includes multiple distillation units mounted side-by-side. Each unit includes a reactor bath for holding molten tin at approximately 455° C., a two-compartment reservoir for storing molten tin, and a porous basket pivotally mounted within the reactor bath for tipping motion. A process for batch thermolytic distillation of lump carbonaceous material includes rotating the porous basket into a reactor bath by rotating the basket about an axis passing through the reactor bath; putting a charge of wood into the basket; closing a retractable lid onto the reactor bath; filling the reactor bath with molten material to produce gas and char by thermolytic conversion of the charge, draining the reactor bath of molten material while the lid is closed; quenching the char in the reactor bath with steam; opening the lid; and tipping the char from the basket.

Abstract: An improved process and apparatus for the destructive distillation or pyrolysis of rubber, such as used rubber tires, to produce liquid and gaseous hydrocarbons and a solid carbonaceous char. A heat transfer gas circulating in a circulation loop is used to cool the hot char produced in the distillation chamber of a distillation oven, the circulation loop having some means for removing the heat transferred to the heat transfer gas from the hot char. In one embodiment, two distillation ovens are operated in off-set, batchwise distillation cycles. The distillation cycles in the two ovens are coordinated so that a fresh charge of rubber feed is introduced into the distillation chamber of one of the ovens as the distillation of rubber in the other oven is concluded.

Abstract: A rotary hearth calciner for treating petroleum cokes with a puffing inhibitor has a horizontal or inwardly sloping hearth floor rotatable around a vertical axis for receiving particles of coke to be calcined and a central opening in the hearth floor for discharging the coke into a soaking pit. A water cooled, refractory covered feed pipe extending downward into the calciner interior has an inlet for connection to a source of petroleum coke puffing inhibitor and an outlet near the edge of the hearth central floor opening for adding the puffing inhibitor to the coke as the coke is discharged from said hearth floor. The feed pipe outlet is approximately at or below the level of the hearth floor to reduce loss of inhibitor in gas flow above the hearth floor. A puffing inhibitor such as sodium carbonate is supplied by a screw feed mechanism to the feed pipe to add the puffing inhibitor at a desired rate for reaction with the coke. The coke is normally maintained in the soaking pit for about 30 minutes at 1200.

Abstract: Method and apparatus for feeding an oxidant such as air and/or a fuel rich gas within the confines of a substantially air tight enclosure employed in the heat treatment of volatile containing materials which are deposited on the floor of a rotary hearth mounted within the enclosure. A larger number of air and/or fuel rich gas inlet ports are provided in the roof of the enclosure at the outer periphery thereof than at the central or intermediate areas of the enclosure to thus provide a more oxidizing atmosphere at the outer peripheral area of the enclosure than at the central and intermediate areas of the enclosure. The oxidant is admitted into the furnace enclosure through concentrically arranged rows of inlet openings formed in the roof of the enclosure.

Abstract: The rabbles of this invention have a concave active face. They are used in a system for processing material including, for example, a substantially circular and horizontal floor, and a rabble system disposed above, but adjacent to, said floor. The rabble system urges material on the floor to desired locations, such as discharge openings, in response to relative motion between the floor and the rabble system. The rabble system includes a plurality of rabbles. Substantially each rabble has a body portion which carries a curved or angled surface. This curved or angled surface defines a concave active face. Each rabble also has a leading edge substantially perpendicular to the floor. The concave active face extends from the leading edge and is both substantially parallel to the leading edge and substantially perpendicular to the floor. Said rabbles are preferably oriented in a system with their body portion adjacent their leading edges at an angle in the range of about 0.degree. to about .+-.13.degree.

Abstract: Method and apparatus for the heat treatment of volatile containing materials in a rotary hearth type furnace wherein the flue gases emanating from the calciner are employed to create either a positive or negative pressure within the calciner hearth as well as the soaking pit area of the said calciner.
