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. More specifically the-pyoil is present in said feedstock in an amount of not more than 20% by weight, based on the total weight of the feedstock.
Claims20
A cracker feedstock composition comprising a recycle content pyrolysis oil composition (r-pyoil), wherein said r-pyoil is present in said feedstock in an amount of 1% to 20% by weight, based on the total weight of the feedstock;
- wherein at least 50 weight percent of said r-pyoil is obtained from the pyrolysis of recycled waste plastic;
- wherein said composition is suitable for use in a thermal steam cracking of alkanes to alkenes.
A method for making one or more olefins, comprising:
- (a) combining a recycle content pyrolysis oil composition (r-pyoil) with a non-recycle C5 to C22 hydrocarbon stream to form a cracker feed stream, wherein said r-pyoil is present in said cracker feed stream in an amount of 5% to 20% by weight;
- wherein at least 50 of said r-pyoil is obtained from the pyrolysis of recycled waste plastic;
- and wherein said cracker feed stream is suitable for use in a thermal steam cracking of alkanes to alkenes;
- and
- (b) cracking said cracker feed stream in a cracker furnace to provide an olefin-containing effluent stream.
