Processes for direct conversion of crude oil to light olefins and light aromatics through steam enhanced catalytic cracking over a core shell cracking catalyst

A process for converting a hydrocarbon feed may comprise contacting a hydrocarbon feed with steam in the presence of a cracking catalyst under steam enhanced catalytic cracking conditions. The contacting the hydrocarbon feed with the steam in the presence of the cracking catalyst may cause at least...

Zusammenfassung:A process for converting a hydrocarbon feed may comprise contacting a hydrocarbon feed with steam in the presence of a cracking catalyst under steam enhanced catalytic cracking conditions. The contacting the hydrocarbon feed with the steam in the presence of the cracking catalyst may cause at least a portion of the hydrocarbon feed to undergo steam catalytic cracking reactions to produce a cracked effluent comprising C2 to C4 olefins, C6 to C10 aromatic compounds, or both. The cracking catalyst may be a nanoparticle comprising: a core and a shell. The core may comprise one or more ZSM-5 zeolite particles and have an outer surface. The shell may comprise a plurality of fibers extending radially outward from the outer surface of the core. The plurality of fibers may comprise silica.
