Patent number: 11708533Abstract: 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.Type: GrantFiled: August 25, 2021Date of Patent: July 25, 2023Assignee: RES Polyflow LLCInventors: George W.

Patent number: 11118114Abstract: 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.Type: GrantFiled: February 28, 2020Date of Patent: September 14, 2021Assignee: RES POLYFLOW LLCInventors: Jay Schabel, Richard A.

Publication number: 20200290908Abstract: An aerobic bio-restoration aqueous system is contained in an artificial ecosystem that treats contaminated water to yield a natural balance or state wherein indigenous flora, fauna, insects and animal life thrive. The system contains a reactor that has exterior walls for enclosing contaminated water. The walls can be solid, but generally contain one or more perforated areas. An important advantage of the present invention is that the perforated areas such as openings, holes, etc., allow the aqueous matter to flow into as well as out of the artificial ecosystem. The ecosystem reactor can be located in a lake, a pond, or other aqueous environments. Water can flow into the artificial ecosystem and be bio-remediated, by utilizing natural flow and/or currents of the aqueous ecosystem. Various types of one or more inert media substrates containing pores that generally contain one or more microorganisms therein serve to bio-remediate various matter contained in the aqueous system such as contaminated water, e.g.Type: ApplicationFiled: March 13, 2020Publication date: September 17, 2020Inventors: Mehmet A.
