Abstract: A plastic pyrolytic conversion vessel comprises a conveying mechanism for moving a liquid, or a semi-molten, or a molten waste material, or a solid inert residue, or any combination thereof through the vessel. During pyrolyzation of the waste material, the same is heated and vaporized and undergoes in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, and is subsequently removed from the vessel. A plurality of scraper blades serve to mix the liquid, or the semi-molten, or the molten waste material, or a solid inert residue, or any combination thereof and convey the waste material forward toward a vessel egress. In another embodiment, one or more sweeping devices serve to move forward the waste material that is located between adjacent rotating conveyor devices.

Abstract: A plastic conversion feeding system serves to transport a feedstock through different processing units or stations to a vessel wherein chemical and/or physical reactions occur to produce suitable, useful end products. Various processing units include a homogenizer for breaking up said feedstock, a size reduction device for reducing the feedstock to particles and densifying the same, a heating and/or blending device for heating said feedstock, and a feed conduit connecting said heating and blending device to said vessel. The feedstock conversion unit vessel through various cracking, reforming, condensation, recombination, and recracking operations, produces a mixture of useful gases and condensable gases.

Abstract: Plastic conversion vessels such as pyrolytic reactors convert plastic waste materials such as polymers, or hydrocarboneous material, or both, via in situ chemical reactions comprising cracking, recombination, reforming, recracking, and the like, to usable chemical compounds such as naphtha, diesel fuel, heavy oil, wax, and the like. Inherent within the polymers and/or carbonaceous material are generally solid, inert residues such as various fillers, pigments, flame retardants, silica, aluminum, talc, glass, clay, and so forth. Such solid inert residues (SIR) must be treated to remove residual volatile organic material therefrom in order to meet acceptable environmental standards and/or limits. A heated dryer for treating the SIR comprises heating units to remove excessive volatile organic material therefrom as when moved along a conveyor that transfers said material to a collection area. The collection area comprises one or more pistons that are capable of compacting and discharging said SIR material.

Abstract: 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.

Abstract: Processes for pyrolyzing hydrocarbonaceous material are provided. A process for pyrolyzing hydrocarbonaceous material includes charging a reactor with a feed material comprising hydrocarbonaceous material, heating the feed material, and collecting liquid product from the reactor which is anaerobic in operation. At least 5% of the organic carbon atoms which are not present in an aromatic ring of a compound of the feed material are present in an aromatic ring of a compound in a liquid portion of the product.
