Abstract
A fluid catalytic cracking catalyst composition (FCC catalyst composition) includes an FCC catalyst and from 1 wt.% to 30 wt.% aromatization-promoting FCC additive. The FCC catalyst includes a USY zeolite, and the aromatization-promoting FCC additive is an MFI zeolite modified with an aromatization compound. The aromatization compound is a metal or metal oxide that includes a metal element from periods 4-6 of the IUPAC periodic table. A method for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with the FCC catalyst composition at reaction conditions sufficient to upgrade at least a portion of the hydrocarbon feed.
