摘要： A pyrolysis method and system are provided that enhances the production of alkanes and minimizes the production of aromatics in the resulting pyrolysis oil. More particularly, the disclosed pyrolysis method and system may be configured to enhance the production of alkanes due to the use of certain pyrolysis catalysts and more intense pyrolysis conditions.

摘要： Processes and facilities for providing recycled content hydrocarbon products (r-products) from separation of pyrolysis gas formed by pyrolyzing waste plastic are provided. Various separation schemes may be employed to process the recycled content pyrolysis gas (r-pygas) into one or more recycled content hydrocarbon streams, which can be used in forming a variety of recycled content products.

摘要： Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). The r-olefin may then be further separated into product streams in a separation zone downstream of the cracker furnace. In some cases, presence of recycle content hydrocarbons may facilitate more efficient operation of one or more distillation columns in the separation zone, including the deethanizer and ethylene fractionator.

摘要： Processes and systems for making recycle content hydrocarbons, including olefins, using a cracker furnace having enhanced coil design. In some cases, the design of the furnace may prevent coking, so that the run length of the furnace is longer than conventional cracking furnaces. Cracker feed streams to the furnace can include recycle content pyrolysis oil and may be used to form olefin-containing effluent stream having recycle content.

摘要： A pyrolysis method and system are provided that utilizes a hydrogen gas or steam in order to enhance the pyrolysis oils produced from recycled plastic wastes. More particularly, the disclosed pyrolysis method and system may be configured to co-feed a hydrogen gas or steam and various types of waste plastics, including post-customer and post-industrial wastes, into a pyrolysis unit and thereby produce desirable pyrolysis oils.

摘要： A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content glycol ester by deducting from a recycle inventory a recycle content value applied to a glycol ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a glycol ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

摘要： Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). In some cases, a heavy fraction from the cracker effluent may be used to form a recycle content pyrolysis gasoline composition (r-pyrolysis gasoline).
