11 Claims

1. A process for making olefins, said process comprising:

(a) cracking a stream comprising a recycle content pyrolysis oil composition (r-pyoil) in a fluidized catalytic cracking (FCC) unit to form an FCC effluent; wherein said FCC effluent comprises a recycle content C5 to C22 hydrocarbon composition (r-C5 to C22);

(b) separating the FCC effluent to form an FCC product stream comprising predominantly C4 and lighter components; and

(c) further separating at least a portion of said FCC product stream in a fractionation zone of a thermal cracking unit to form an olefin product comprising predominantly propylene; wherein the process further comprising combining at least a portion of said FCC product stream with at least a portion of the olefin product from the fractionation zone of said thermal cracking furnace unit.
