Catalyst for the 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 catalyst composition useful for producing olefins and aromatic compounds from a plastic feedstock, the catalyst composition comprising:
a mixture of fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, the FCC catalyst comprising a non-fresh FCC catalyst formed from a large pore molecular sieve or zeolite having a total surface area of from 100 m2/g to 400 m2/g, and wherein the amount of ZSM-5 zeolite catalyst makes up from 10 wt. % to 50 wt. % of the total weight of the FCC catalyst and the ZSM-5 zeolite catalyst.
