    摘要： 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.

    摘要： A process for producing at least one light olefin comprising: (a) contacting a first raw material comprising methanol with a least one catalyst in a first reaction zone to produce at least one light olefin and at least one inactivated catalyst; (b) transporting the at least one inactivated catalyst to a first regeneration zone to produce at least one first regenerated catalyst, and transporting a portion of the at least one first regenerated catalyst to the first reaction zone; (c) transporting another portion of the at least one first regenerated catalyst to a second regeneration zone to obtain at least one second regenerated catalyst; and (d) transporting the at least one second regenerated catalyst to a second reaction zone, and contacting the at least one second regenerated catalyst with a second raw material comprising C4 olefins to produce a product stream II comprising at least one light olefin.
