Systems and methods are provided for integration of polymeric waste co-processing in cokers to produce circular chemical products from coker naphtha, including a method of producing circular chemical products comprising: providing a coker naphtha that is at least partially derived from polymeric waste, wherein the coker naphtha has a total halide content of about 1 wppm to about 0.5 wt %, a 2-3 ring aromatic content of about 0 wt % to about 5 wt %, and a sulfur content of about 750 ppm to about 2 wt %; and converting the coker naphtha into at least a polymer.

Pre-treating a waste polyester material with dichloromethane (DCM) produce purified polyester for reuse. The purified polyester can be recycled via any chemical or mechanical recycling process. Where the waste polyester material includes non-polyester contaminants, the DCM-treated polyester material produces a slurry that includes the DCM, a solid component that includes a polyester monomer product for reuse, and a waste liquid component where the non-polyester contaminants can be filtered from the top of the liquid component.

A device for processing scrap rubber has a reactor with a screw conveyor disposed inside a heating chamber, a thermal decomposition unit, burners, a condenser, a cyclone filter, and devices for discharging solid residue and removing a gas-vapor mixture. The reactor has two sections connected in parallel. The thermal decomposition unit has screw conveyors in each section, the conveyors have axial heating pipes with a coil. Along the length of the conveyors plates are arranged at the corners of an equilateral triangle in contact with and perpendicular to the side surface of the heating tube. A cylinder furnace with an evaporator and a burner is connected to the ends of the pipes. An outlet of the condenser is connected to a liquid fraction separator, inlets of the coils are connected to an outlet of the evaporator, and an inlet of the evaporator is connected to an outlet from the separator.

The invention relates to the recycling of used rubber products, more specifically to the recycling of Ground Tire Rubber (GTR) from cars and trucks. Provided is a method for reclaiming rubber, comprising the steps of (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200? C. to achieve at least a partial destruction of the cross-links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.
