Abstract
A process for upgrading a hydrocarbon feed comprises contacting the hydrocarbon feed with steam in the presence of a cracking catalyst composition at reaction conditions sufficient to cause at least a portion of hydrocarbons in the hydrocarbon feed to undergo one or more cracking reactions to produce a steam catalytic cracking effluent comprising light olefins, light aromatic compounds, or both, where the cracking catalyst composition comprises a cracking additive comprising metal species impregnated on a ZSM-5 zeolite, where the metal species comprises a metal selected from the group consisting of chromium, vanadium, iron, platinum, molybdenum, cerium, and nickel.
