  • Patent number: 12104121
    Abstract: A mixed ester composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content mixed ester or by deducting from a recycle inventory a recycle content value applied to a mixed ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a mixed ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

  • Patent number: 12098338
    Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. Alternatively, the r-pyoil with a predominantly c8+ fraction can be fed to the cracker feed. The furnace can be a gas fed furnace, or split cracker furnace.

  • Publication number: 20240309276
    Abstract: A predominantly C2 to C4 hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to a first coil while a second cracker feed with none of the r-pyoil or less of the r-pyoil is fed to a second coil, and both are cracked in a cracker furnace to form an olefin-containing effluent stream. Alternatively, the r-pyoil can be fed and distributed across multiple coils along with the non-recycle cracker feed. The furnace can be a gas fed furnace, or split cracker furnace. Further, a first cracker stream with r-pyoil in a first coil can have a lower total molar flow rate than a second cracker stream in a second coil in the same furnace.

  • Publication number: 20240262701
    Abstract: A process for making recycle content ammonia by reacting hydrogen with nitrogen. At least a portion of the hydrogen is obtained directly or indirectly by molecular reforming a mixed plastic waste or pyrolysis product feedstock. The molecular reforming can be a steam reforming process or a partial oxidation process, such as a partial oxidation gasifier, to generate the syngas used as a source of hydrogen. The recycle content associated with the ammonia can be obtained from the mixed plastic waste, the recycle content in the pyrolysis product, such as pyoil or pygas, or the recycle content in the syngas or the purified hydrogen stream from the syngas.

  • Publication number: 20240218258
    Abstract: 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, the pyrolysis and cracking may be carried out in different sections of the same furnace, or in different furnaces in the same cracker facility. Pyrolysis conducted in a furnace may or may not require retrofitting a furnace previously used to crack alkanes to form olefins.

  • Patent number: 11787754
    Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, are provided that integrate a cracker unit with one or more other processing units. For example, in some cases, a fluidized catalytic cracking unit may be used to crack recycle content pyrolysis oil and the effluent from the FCC may be further processed in a conventional cracker unit, including its downstream separation zone, to provide recycle content hydrocarbon product stream. In other cases, a pyrolysis unit and cracking unit may be co-located and may share at least one utility, service group, boundary, conduit, energy exchange zone, and/or geographical area.
