Zusammenfassung:	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 a ZSM-5 zeolite, a first metal species, and a second metal species, where the first metal species and the second metal species are impregnated onto the ZSM-5 zeolite, the first metal species comprises a metal or metal oxide comprising a first metal, the second metal species comprises a metal or metal oxide comprising a second metal, and the second metal is different from the first metal.
