摘要：
A process for producing high purity propylene comprises: a step for dimerizing ethylene to 1-butene; a step for hydroisomerizing 1-butene to 2-butenes; and a step for metathesis of 2-butenes by ethylene. Advantageously, the ethylene used to produce the 1-butene and ethylene for metathesis derive from a steam cracking unit. To increase propylene production, the process can use a steam cracking or FCC C4cut as an additional butene source.
