CONVERSION OF PLASTICS TO OLEFIN AND AROMATIC PRODUCTS WITH PRODUCT RECYCLE

摘要

A method of producing olefins and aromatic compounds from a feedstock is accomplished by introducing a hydrocarbon feedstock and a catalyst composition within a reactor. At least a portion of the reactor is at a reactor temperature of from 470°C to 730°C. The catalyst composition is comprised of a fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, wherein the amount of ZSM-5 zeolite catalyst makes up from greater than 0 wt.% of the total weight of the FCC catalyst and the ZSM-5 zeolite catalyst. At least a portion of the feedstock is converted to products of at least one of olefins and aromatic compounds within the reactor, with at least some of the products being contained in a liquid product stream. At least a portion of the liquid product stream is directed to different downstream processes to increase production of at least one of olefins and aromatic compounds.
