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.
