An environmental friendly, continuous biomass torrefaction system is disclosed herein. This torrefaction system captures carbon dioxide (CO.sub.2) from the combustion gases generated in the process. A portion of the captured CO.sub.2 is recycled and used as the inert gas for torrefying biomass and cooling the torrefied biomass. The rest of the captured CO.sub.2 is stored.

A method for processing plastics includes receiving input plastics to be processed. The method further includes driving the input plastics through a reactor chamber having at least two zones each containing heated fluid that is heated to greater temperatures in a subsequent zone such that remaining plastics of the input plastics are exposed to increasingly greater temperatures in each zone of the reactor chamber. The method also includes collecting condensable vapors that flow out of the at least two zones of the reactor chamber. The method further includes condensing the condensable vapors into a liquid condensate. The method also includes removing biochar products from the heated fluid. The method further includes removing contaminants from the reactor 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.

The present invention relates to a device and a method for low-temperature pyrolysis, wherein: waste tire chips are continuously supplied; since a pneumatic method of an intake method and a blowing method is adopted, the waste tire chips may be quickly fed (supplied) by a simple method, and only the waste tire chips may be supplied into a pyrolysis reactor but the inflow of air thereinto may be fundamentally blocked, thereby increasing the pyrolysis efficiency of the pyrolysis reactor and preventing the explosion reaction thereof; and unlike the prior art, a mechanical conveyor supply method is not used, and thus waste tire chip supply equipment can be miniaturized and modularized, thereby enabling the compact design of the pyrolysis equipment, facilitating a pyrolysis operation, facilitating maintenance, and significantly reducing the site area of the pyrolysis equipment or the cost of manpower input for supplying waste tire chips.
