  • Patent number: 12091620
    Abstract: 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.

  • Publication number: 20230407189
    Abstract: This disclosure provides processes for reforming hydrocarbons by using a series of adiabatic reactors and catalysts, in which the catalyst(s) in at least one front or upstream catalyst bed or reactor includes a higher fluoride concentration, higher chloride concentration, or both than the respective halide concentrations in the catalysts in one or more downstream catalyst beds or reactors, which has been unexpectedly discovered to extend the useful life and/or the selectivity of the catalyst system.

  • Patent number: 11713424
    Abstract: 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.
