摘要： A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.

摘要： A process for operating a reforming system by operating a reforming section containing a plurality of reactors, wherein each of the plurality of reactors containing a reforming catalyst capable of catalyzing the conversion of at least a portion of the hydrocarbons in a treated hydrocarbon stream into a reactor effluent comprising aromatic hydrocarbons, and operating a sulfur guard bed (SGB) to remove sulfur and sulfur-containing hydrocarbons from a hydrocarbon feed to provide the treated hydrocarbon stream, where the SGB contains at least a layer of a SGB catalyst comprising the same catalyst as the reforming catalyst, and where each reactor of the plurality of reactors within the reforming section may be operated at a higher operating temperature than an operating temperature of the SGB. A system for carrying out the process is also provided.

摘要： This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.

摘要： This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based or fossil fuel co-feed, or as a feedstock in the absence of a petroleum-based or fossil fuel co-feed. A mass balance accounting approach is employed to attribute the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit, which permits assigning circular product credit to product streams. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways.
