An arrangement for the recycling of carbon and hydrocarbon compounds from organic input material is provided. The arrangement includes: a reactor comprising a chamber that is limited by a jacket and upper and lower end-wall sections, gas inlet means for the supply of heated inert gas to the input material, whereby the gas inlet means is connected in a manner that transfers gas to a gas emission source, and gas outlets for leading the gas out of the chamber, where the gas outlet means comprises openings through which gas flows intended to supply the gas into the chamber, whereby the openings through which gas flows are arranged such that a fall in pressure is generated during the supply of gas that exceeds the fall in pressure of the gas during passage through the input material that has been introduced into the chamber. A corresponding method is also described.

Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

The invention relates to a multilayer plastic film, in particular a multilayer plastic composite film, preferably a multilayer plastic packaging film, based on plastic recyclate (recycled plastic), in particular based on plastic recyclate originating from waste, with a plastic recyclate content of at least 80% by weight, based on the plastic film, and to its use, in particular as packaging material. The plastic recyclate is preferably post-consumer plastic recyclate (PCR plastic recyclate), in particular PCR recycled films.

Disclosed are antifouling agents used in compositions and methods to reduce or prevent foulants in synthetic feedstocks derived from plastic. A method of reducing or preventing fouling in a plastic-derived synthetic feedstock composition may include adding an antifouling agent including a carboxylic acid anhydride or a copolymer of a dicarboxylic acid anhydride and alpha olefin to a synthetic feedstock composition derived from plastic pyrolysis containing a foulant to provide treated pyrolysate. The foulant may include, for example, nylon, polyvinyl chlorides, polyethylene terephthalate, polyamides, caprolactam, benzoic acid, phenol, p-cresol, dimethylphenol, isopropyl phenol, tert-butylphenol, dimethylethylphenol, napthalenol, varying lengths of alkenes and alkanes, propylene, tolune, pentene, butane, tetramethylindole, ethylbenzene, ethyldimethylpyrrole, dimethylfuran, tetrahydroquinoline, and any combination thereof.

Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

The present invention relates to a process for purifying a pyrolyzed plastic waste, the process comprising the steps of providing the pyrolyzed plastic waste, wherein the pyrolyzed plastic waste is a liquid or a wax at 20° C. and 1 atm, contacting the pyrolyzed plastic waste with activated carbon yielding a pretreated 5 plastic waste and hydrogenating the pretreated plastic waste using hydrogen and a metal-based catalyst yielding a hydrogenated plastic waste suitable for steam cracking.

Systems and methods are provided for conversion of polymers (such as plastic waste) to olefins. The systems and methods can include an initial pyrolysis stage where a plastic feedstock is delivered to the initial pyrolysis stage by one or more melt extruders. The one or more melt extruders can be heated to maintain the plastic feedstock in a liquid state during delivery of the plastic feedstock to the initial pyrolysis stage. This can allow for delivery of the plastic feedstock into the pyrolysis process with a controlled distribution of plastic into the pyrolysis reactor.

Systems and methods for processing waste plastics are provided. One method includes mixing, heating and compacting a supply of the waste plastic based feedstock having an appreciable amount of halide compounds or heteroatoms from one or more sources of contamination; providing an amendment comprising alkaline earth oxides and/or hydroxides, oxides of iron, and/or oxides of aluminum to be mixed, heated and compacted with the waste plastic based feedstock to form a densified melt of plastic material including the amendment; and pyrolyzing the densified melt of plastic material including the amendment within a pyrolysis reactor. Another method includes pyrolyzing a supply of the waste plastic feedstock within a pyrolysis reactor to generate a hydrocarbon gas stream and a solids residue stream; condensing out a tars product from the hydrocarbon gas stream output from the pyrolysis reactor with a quenching apparatus; and pyrolyzing the tars product within a supplemental pyrolysis reactor.

The invention relates to the field of road construction materials, and it is intended to improve the quality of road surfaces, roofing and insulating materials based on bitumens, which is achieved by improving the quality of bitumens with the help of using modified crumb rubber—a disposal product of used automotive and tractor tires, in particular, the invention relates to a low-temperature method for manufacturing modified crumb rubber to improve the quality of bitumens and asphalt concretes and to the technology for mixing it with bitumen, for the purpose of creating a uniform material that is not prone to destruction during long-term storage. The present invention consists in the development of a new method for manufacturing the modified crumb rubber, comprising preparing a mix from the following components: crumb rubber from used automotive and tractor tires with a particle size of up to 1 mm—50-65 wt. %, oxides and/or hydroxides of alkaline-earth metals—10-20 wt. %, petroleum oil of solvent refining with the viscosity of from 0.05 to 1.5 Pa*s at 60° C.—20-30 wt. %, an amine type antiageing agent—a heterocyclic nitrogen-containing compound—0.1-2.0 wt. %; mixing the components of the resulting mix with a shock-shear load on the material in a mixer-activator at a temperature of 80-120° C.; and further cooling the resulting mix to a room temperature.
