The device for pyrolysis of carbonaceous materials comprises a working chamber comprising a non-magnetic wall comprising an inner graphite lining; one or more electrodes adapted to be inserted within a carbon-based bedding; a solenoid coiled around the device exterior, the solenoid adapted to create a magnetic field within the working chamber such that when the solenoid is energized, the carbon-based bedding is caused to move; a lower solids outlet comprising an airlock, the solids outlet adapted to permit solids to exit the device; and a lower gas outlet adapted to permit gaseous substances to exit after having traveled through the carbon-based bedding. The method comprises the steps of loading carbon-containing materials into the working chamber; using the first and second electrodes to heat the carbon-containing materials by passing electric current through the carbon-containing materials without air access; collecting, cleaning and releasing gaseous pyrolysis products produced by the heating.

Plastic conversion vessels such as pyrolytic reactors convert plastic waste materials such as polymers, or hydrocarboneous material, or both, via in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, to usable chemical compounds such as naphtha, diesel fuel, heavy oil, wax, and the like. Inherent within the polymers and/or carbonaceous material are generally solid, inert residues such as various fillers, pigments, flame retardants, silica, aluminum, talc, glass, clay, and so forth. Such solid inert residues (SIR) must be treated to remove residual volatile organic material therefrom in order to meet acceptable environmental standards and/or limits. A heated dryer for treating the SIR comprises heating units to remove excessive volatile organic material therefrom as when moved along a conveyor that transfers said material to a collection area. The collection area comprises one or more pistons that are capable of compacting and discharging said SIR material. Another collection area embodiment comprises a plurality of plungers that transfer the SIR material from said collection area to a plunger collection area, and subsequently to a collection container.

A method, system, and apparatus for decomposing a biomass feedstock include providing a layer of inert particulate matter, such as sand, to line and insulate the bottom surface of a main chamber of a reactor where pyrolysis and oxidation are conducted to produce char and producer gases as primary products. In an embodiment, feedstock positioned in a side region of the reaction chamber insulates side walls of the main chamber from heat in the center region of the main chamber. In an embodiment of the method, a rate of removal of solid products such as char from the reactor is controlled in response to a temperature detected at a position of an extraction tube inlet of the reactor. Activated charcoal may be obtained as a primary product using the system and method, by feeding oxygen into the reactor at an inlet positioned adjacent to an inlet to the extraction chamber.

Examples of a flexible pyrolysis system are provided that include at least one reaction chamber capable of pyrolyzing a combination of coal in a supercritical carbon dioxide (CO.sub.2) atmosphere. The system includes a recuperating and condensing circuit that removes dissolved pyrolysis products from the supercritical CO.sub.2 atmosphere and then recovers CO.sub.2 for reuse in the reaction chamber. The recuperating and condensing circuit includes multiple stages of recuperators and collectors that can be independently controlled in order to selectively fractionate the pyrolysis products. In addition, the pyrolysis reaction may be controlled to alter the pyrolysis products generated.
