A process is described for treating waste plastics material to provide at least one on-specification fuel product. Plastics material is melted and then pyrolyzed in an oxygen-free atmosphere to provide pyrolysis gases. The pyrolysis gases are brought into contact with plates in a contactor vessel so that some long chain gas components condense and return to be further pyrolyzed to achieve thermal degradation. Short chain gas components exit the contactor in gaseous form and proceed to distillation to provide one or more on-specification fuel products. A pipe directly links the pyrolysis chamber to the contactor, suitable for conveying upwardly-moving pyrolysis gases and downwardly-flowing long-chain liquid for thermal degradation.

A continuous solid organic matter pyrolysis polygeneration system and method for using the system is disclosed. The pyrolysis polygeneration system mainly includes a processing system, a drying furnace, a pyrolysis furnace, a cooling furnace, a tail gas treatment system, and a gas treatment system and a protective gas circulation system cooperate with each other to realize the multi-level rational utilization of energy, and are suitable for the continuous and rapid pyrolysis and carbonization of various solid organic matter in the actual production. While realizing the polygeneration of coke, wood vinegar and tar, the maximum utilization of overall heat is realized through process optimization.

A system for thermally processing solid fuel to produce pyrolysis gases, syngas, tar, char, and/or torrefied products, which includes a bulk solids pump having a curved passage to move a feedstock therein and wherein the pump includes a spool supported for rotational movement. A sleeve shaped chamber or chambers surround all or a portion of at least an axial extent of said curved passage to permit containment of heated gases to heat solid fuel within the curved passage to thermally process the feedstock within the pump.
