Abstract
The present application discloses a recycle content cracked effluent composition having a certain compositional profile produced by cracking a cracker feed comprising a recycle content pyrolysis oil composition, and methods of producing the recycle content cracked effluent composition.
Claims18
A recycle content cracked effluent composition (r-cracked effluent) exiting a coil of a radiant section of a cracker furnace, wherein said r-cracked effluent is produced by cracking a cracker feed comprising r-pyoil, said r-cracked effluent comprising:
- propylene in an amount ranging from 0.5 to 30 weight percent;
- and
- ethylene in an amount ranging from 40 to 90 weight percent;
- and
- wherein said r-pyoil has not been hydrogenated;
- and wherein said r-pyoil comprises not more than about 30 weight percent total aromatics, based on the total weight of said r-pyoil.
A recycle content cracked effluent composition (r-cracked effluent) formed by cracking a cracker feed stream comprising r-pyoil, to produce an olefin-containing composition having an olefin-to-aromatic weight ratio of greater than 2:1;
- wherein said r-pyoil has a C8+content of at least 35 weight percent, based on the total weight of said r-pyoil;
- and wherein said r-pyoil comprises not more than about 30 weight percent total aromatics, based on the total weight of said r-pyoil.
A recycle content cracked effluent composition (r-cracked effluent) formed by cracking a cracker feed stream comprising a recycle content pyrolysis oil composition (r-pyoil);
- wherein said r-pyoil has not been hydrogenated;
- and wherein said r-pyoil comprises not more than about 30 weight percent total aromatics, based on the total weight of said r-pyoil;
- and wherein said r-cracked effluent has an elevated amount of one or more of the following compounds (i) through (iiii):
- (i) butadiene;
- (ii) cyclopentadiene;
- and (iii) dicyclopentadiene, wherein said elevated amount is relative to r-cracked effluent made with said cracker feed stream except without said r-pyoil and at the same mass cracker feed rate.
