A method and system for extracting hydrocarbon fuel products from plastic material provides extraction of usable fuel components from waste plastic materials. The materials (or hydrocarbon portion thereof) are liquified and introduced to a chamber where the liquid material is agitated and a negative relative pressure (vacuum) is applied. The liquid is maintained at a substantially constant temperature and the vacuum draws the off-gas hydrocarbon products out for condensation and further processing, while unconverted char is removed to an ash dump. An auger feed unit with agitator buckets is used to propel the char through a feed while agitating the liquid to enhance the rate of gas removal.

The invention discloses a powdered coal coking device and a powdered coal coking method. The powdered coal coking method includes: installing declivitous powdered coal bearing plates in a carbonization chamber layer by layer; forming multiple layers of heat exchanging units communicated mutually by utilization of the multiple powdered coal bearing plates, wherein a powdered coal accumulation region and a gas flow region which are based on a powdered coal bearing plate are arranged on each layer of heat exchanging unit, so that a powdered coal coking environment is formed in which powdered coal and gas can flow; distributing the powdered coal to each layer of the heat exchanging unit from top to bottom to enable a powdered coal layer distributed in a slanted mode to be accumulated on the powdered coal accumulation region on each heat exchanging unit; and by utilization of the gas flow region of each layer, heat-carrying gas generated through combustion or heating flowing to each heat exchanging region from bottom to top and exchanging heat with the powdered coal layer of each heat exchanging unit to generate powdery semi-coke, coal gas and coal tar.

An apparatus for separating carbon products from used tires includes a decomposing chamber into which used tires are charged, a nitrogen gas supply device that supplies nitrogen gas into the decomposing chamber, one or more magnetrons that generate microwave of predetermined frequency and one or more phase shifters that removes interference between microwaves generated by the magnetrons, a receiving plate that is adapted to receive carbon black and iron cores generated by the decomposing process, a tire support that is adapted to support used tires, an opening and closing device that opens or closes a door on which used tires are placed, conveyor belt that moves carbon black and iron cores to a desired location after decomposition is complete, and a cooling plate that is provided in an upper portion of the apparatus and cools down gaseous oil that is generated by decomposition by microwave into liquid oil.

A system and method for a constituent rendering of biomass and other carbon-based materials is provided. The system can be configured for receiving a feedstock material to be rendered into its constituent components, grinding the feedstock to a desired size and / or consistency, and placing the feedstock in contact with a hot mix heat transfer medium within a pressure chamber. In an aspect, the system can utilize a feedstock input system to receive the feedstock material, with the feedstock input system including an auger feed tube, at least one feed stock auger screw, a grinding station with a die configured to interact with the feed stock auger screw, and a movable compression gate. Pyrolysis of the feedstock can lead to a breakdown of the feedstock into constituent components that can then be collected.
