1. A method of processing a pyrolysis oil, the method comprising;
processing a pyrolysis oil obtained from pyrolysis of a plastic in a catalytic cracking unit, a hydrocracking unit, and/or a thermal cracking unit under reaction conditions sufficient to produce a gaseous stream comprising propylene and a liquid stream with a boiling range of 35 to 400° C.; and
processing the liquid stream to produce additional propylene,
wherein a portion of the pyrolysis oil or the entire pyrolysis oil is blended with vacuum residue to form a first pyrolysis oil blend, and the first pyrolysis oil blend is processed in the thermal cracking unit.
