  • Patent number: 11945998
    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.
