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.

There is described a pyrolysis system for converting carboneous materials into biochar including a kiln, a retort, and a gas recovery system including a combustor supplying hot air to the kiln, a conduit fluidly connected between the retort and the combustor, the conduit conveying the pyrolysis gas and residues from a chamber of the retort to the combustor, and a filter cartridge fluidly connecting the chamber of the retort to the conduit for filtering the pyrolysis gas and the residues conveyed from the chamber of the retort to the combustor, the filter cartridge removably located inside the conduit and extending at least partially inside the chamber of the retort. Methods for operating the pyrolysis system are also described. The pyrolysis system and methods described herein produce biochar with improved resistance to self-heating.

The present invention is a pyrolysis system including a furnace for batch pyrolysis processing. The pyrolysis system receives scrap tires or other organic waste materials as inputs and performs batch pyrolysis processing to produce pyro-products as outputs. The pyro-products produced include pyro-vapors from which are condensed pyro-oil with a surviving pyro-gas and also include pyro-solids, particularly pyro-carbon (carbon char) and steel. The pyro-oil includes an inhibitor.
