Abstract

Processes for producing olefins include introducing a hydrocarbon feed to a high-severity fluidized catalytic cracking system, contacting the hydrocarbon feed with a cracking catalyst under high-severity conditions in the high-severity fluidized catalytic cracking system to produce a cracking reaction effluent comprising butene, and passing at least a portion of the cracking reaction effluent, which includes at least butene, to a metathesis system. The processes further include contacting the portion of the cracking reaction effluent with a metathesis catalyst in the metathesis system, which causes at least a portion of the butene in the cracking C4 effluent to undergo a metathesis reaction to produce a metathesis reaction effluent comprising at least one of ethylene, propene, or both. The processes may further include separating a metathesis C5+ effluent from the metathesis reaction effluent and passing the metathesis C5+ effluent back to the high-severity fluidized catalytic cracking unit.
