Abstract: Processes for producing olefins include passing a hydrocarbon feed to a hydrocarbon cracking unit that cracks the hydrocarbon feed to produce a cracker effluent, passing the cracker effluent to a cracker effluent separation system that separates the cracker effluent to produce at least a cracking C4 effluent including 1-butene, 1,3-butadiene, and isobutene, passing the cracking C4 effluent to an SHIU that contacts the cracking C4 effluent with hydrogen in the presence of a selective hydrogenation catalyst to produce a hydrogenation effluent having a 2-butenes concentration greater than or equal to the sum of the concentrations of 1-butene and isobutene. The processes include passing the hydrogenation effluent to a metathesis unit that contacts the hydrogenation effluent with a metathesis catalyst and a cracking catalyst downstream of the metathesis catalyst to produce a metathesis reaction effluent comprising at least propene.

Abstract: Processes for producing olefins include integration of steam cracking with a dual catalyst metathesis process. The processes include steam cracking a hydrocarbon feed to form a cracking reaction effluent containing butenes, separating the cracking reaction effluent to produce a cracking C4 effluent including normal butenes, isobutene, and 1,3-butadiene, subjecting the cracking C4 effluent to selective hydrogenation to convert 1,3-butadiene in the cracking C4 effluent to normal butenes, removing isobutene from a hydrogenation effluent to produce a metathesis feed containing normal butenes, and contacting the metathesis feed with a metathesis catalyst and a cracking catalyst directly downstream of the metathesis catalyst to produce a metathesis reaction effluent. Contacting with the metathesis catalyst causes metathesis of normal butenes to produce ethylene, propene, and C5+ olefins, and contacting with the cracking catalyst causes C5+ olefins produced through metathesis to undergo cracking reactions to produce additional propene, ethylene, or both.

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.
