Abstract
A fluid catalytic cracking catalyst composition (FCC catalyst composition) includes a framework-substituted ultra-stable Y-type zeolite (USY zeolite) having one or more transition metals substituted into the framework of a USY zeolite and a FCC zeolite cracking additive. A method for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with the FCC catalyst composition of the present disclosure at reaction conditions sufficient to upgrade at least a portion of the hydrocarbon feed. A method for upgrading a hydrocarbon feed includes passing the hydrocarbon feed to a fluid catalytic cracking unit, contacting the hydrocarbon feed with a FCC catalyst composition in the fluid catalytic cracking unit under reaction conditions sufficient to cause at least a portion of the hydrocarbon feed to undergo cracking reactions to produce a cracking reaction mixture comprising a used FCC catalyst composition and a cracked effluent comprising one or more olefins.
