A drag chain carbonizer is provided with a system and methods for anaerobic thermal conversion processing to convert waste into various solid carbonized products and varied further co-products. The drag-chain carbonizer includes an adjustable bed depth mechanism, a heating mechanism, a pressure management mechanism, an atmospheric management mechanism, and a chain tensioning mechanism containing at least one position sensor for communication of an actuator position to at least one programmable logic controller (PLC). Carbonaceous waste is transformed into useful co-products that can be re-introduced into the stream of commerce at various economically advantageous points. Depending upon the input materials and the parameters selected to process the waste, including real time economic and other market parameters, the system adjusts co-products output to reflect changing market conditions.

A device and process for the vacuum pyrolization of scrap tires to produce a pyrolytic oil from which valuable terpenes such as limonene and pulegone may be extracted and purified.

A pyrolysis apparatus reduces feedstock to gaseous energy sources and recyclable solids by moving feedstock through a processing unit via a feedstock transport mechanism that has sections that move the feedstock at respectively different rates through a retort within the processing unit. The feedstock transport mechanism may be an auger with a variable flighting pitch along its shaft. The pyrolysis apparatus may be modular in that processing units may be added and subtracted as necessary for any given installation. A restriction device squeezes ambient air out of the feedstock prior to entry into the pyrolysis apparatus retort.

Systems and methods for producing product gas fuel and solid char fuel from a carbon-containing feedstock are described. Feedstock is introduced into and transported through at least one substantially horizontal sublimation reaction chamber. An initial and final sublimation temperature is maintained within less than 10 C. in an atmosphere free from external oxygen and externally supplied catalyst. The system is configured to not have any product gas leak out of the reaction chamber or oxygen leak into a hot box configured to heat the reaction chamber.
