  • Patent number: 11866649
    Abstract: A shale pyrolysis system includes a retort with a first side and a second side. The second side is opposite the first side and the first side and the second side include descending angled surfaces at alternating angles to produce zig-zag motion of shale descending through the retort. Corners of the retort that change direction of the shale are rounded. The system includes steam distributors coupled to the first side and collectors coupled to the second side to produce crossflow of steam and heat across the descending shale from the first side to the second side, and a steam temperature control subsystem coupled to the steam distributors and configured to deliver higher-temperature steam to one or more upper sections of the retort and lower-temperature steam to one or more lower sections of the retort.

  • Publication number: 20110024280
    Abstract: Methods and systems for substantially continuously treating comminuted material containing carbon and hydrogen, for example, used tires, are provided. The methods include the steps of introducing the tire material to an elongated chamber, transferring the tire material through the elongated chamber, heating the tire material to a temperature sufficient to pyrolyze the material to produce a gaseous stream; discharging the gaseous stream from the chamber, and cooling at least some of the gaseous stream to liquefy components of the stream. The transfer may be effected by a flexible, center-less screw conveyor to minimize material buildup in the vessel. The cooling of the gaseous stream may be practiced by reverse condensation. One or more re-usable fuel streams are may be provided.

  • Patent number: 4465559
    Abstract: An atomization/distillation unit for separating a component from a mixture containing that component having a chamber, a container incorporated within the bottom of the chamber for receiving the mixture, a heater for heating the mixture to a temperature sufficient to vaporize the component but insufficient to vaporize the entire mixture, an atomizer located within the container for spraying said mixture upward in the chamber thereby aiding in further vaporization of the component, and agitator plates operating in conjunction with the atomizer for propelling the vapor upward in the chamber. Cooling coils are located in the top portion of the chamber in order to condense the vaporized component. Once condensed, the distillate is easily removed from the chamber. The atomization/distillation system is effective in combining atomization and distillation in order to maximize recovery of the desired component in a highly energy efficient manner.

  • Patent number: 4247367
    Abstract: This disclosure is directed to an economical system for the pyrolysis of municipal solid waste to recover valuable by-products while reducing the putrecibility and bulk of the residue requiring disposal. Prior to this treatment, the solid waste has been processed to remove most of the metallic components, and shredded, which steps are not part of the invention disclosed. The pyrolysis and by-product recovery technology is complicated by (a) the inherent variability of the chemical and physical characteristics of the shredded solid waste as received at the pyrolysis plant and (b) the relatively low heat value of said waste as thus received.
