Claim Text:
1. A method of producing olefins and aromatic compounds from a feedstock, the method comprising: contacting a plastic feedstock and a catalyst composition at a temperature of from 420° C. to 730° C. within a reactor, the catalyst composition comprising a non-fresh fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, the amount of ZSM-5 zeolite catalyst of the catalyst composition makes up from 10 wt. % to 50 wt. % of the total weight of the FCC catalyst and the ZSM-5 zeolite catalyst to simultaneously increase production of both light gas olefins and aromatics, the feedstock and the catalyst composition being at a catalyst-to-feed ratio of from 6 or greater; allowing at least a portion of the feedstock to be converted to products of olefins and aromatic compounds within the reactor, at least some of the products being contained in a liquid product stream; and directing at least a portion of the liquid product stream to one or more of the following (A) through (E), wherein:
