Conversion of plastics to olefin and aromatic products

摘要

A catalyst composition useful for producing olefins and aromatic compounds from a feedstock is formed from a fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, wherein the amount of ZSM-5 zeolite catalyst makes up from 10 wt. % or more by total weight of the FCC catalyst and the ZSM-5 zeolite catalyst. The catalyst composition may be used in a method of producing olefins and aromatic compounds from a feedstock by introducing a hydrocarbon feedstock and the catalyst composition within a reactor, at least a portion of the reactor being at a reactor temperature of 550° C. or higher. The feedstock and catalyst composition are introduced into the reactor at a catalyst-to-feed (C/F) ratio of from 6 or greater.

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 550° C. or higher, the catalyst composition comprising a fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, wherein the amount of ZSM-5 zeolite catalyst makes up at least 10 wt. % of the total weight of the FCC catalyst and the ZSM-5 zeolite catalyst, the feedstock and the catalyst composition being at a catalyst-to-feed ratio of from 6 or greater; and allowing at least a portion of the feedstock to be converted to at least one of olefins and aromatic compounds.
