A process and an apparatus for pyrolysis of mixed plastic feedstock producing petroleum products are described. In one example, a process for producing petroleum products includes charging feedstock of mixed polymer materials into a reactor apparatus. Heat energy is applied to the feedstock while advancing the feedstock through the reactor apparatus in an anaerobic operation. The energy input to the reactor apparatus is controlled by controlling a temperature gradient within the reactor vessel to produce petroleum gas product. The process involves in situ chemical reactions comprising cracking and recombination reactions that that are controlled to convert solid hydrocarbonaceous portion of the feedstock to molten fluids and gases inside the reactor vessel and to produce gaseous petroleum products which exit the reactor vessel. The separated solid residue from the pyrolysis process is also removed from the reactions vessel.

Disclosed herein is a kiln 100 for use in the production of hydrocarbon fuels from plastics. The kiln 100 comprises a scrubber 200 in fluid communication with a reaction chamber 130, the scrubber 200 being configured to condense hydrocarbons in the reaction chamber gas product stream 501 above a predetermined upper hydrocarbon range for returning to the reaction chamber 130 for further heating in the absence of oxygen. Also disclosed herein is a method of converting waste plastics to a commercially-useful form by way of diesel or the like. The method comprises treating a crude fuel produced from plastics in a pyrolytic process with a first extraction step comprising counterflow liquid-liquid extraction, and a second extraction step comprising counterflow extraction of solvents from the first extraction step.

A churning and stoking ram for a furnace is disclosed. The churning and stoking ram includes a frame disposed externally of the furnace, where the stoking ram is mounted on the frame. The stoking ram is positionable relative to the furnace between an external position and an internal position, and is rotatable about a central longitudinal axis of the stoking ram. The stoking ram further includes a churning device positionable relative to the stoking ram between a retracted position and an extended position, a first actuator mounted on the frame to position the stoking ram between the external and internal positions, a second actuator to position the churning device between the retracted and extended positions, and a third actuator to rotate the stoking ram and the churning device associated therewith.

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.
