According to one embodiment described in this disclosure, a process for producing propylene may comprise at least partially metathesizing a first stream comprising at least about 10 wt.% butene to form a metathesis-reaction product, at least partially cracking the metathesis-reaction product to form a cracking-reaction product comprising propylene, and at least partially separating propylene fromthe cracking-reaction product to form a product stream comprising at least about 80 wt.% propylene. 根据本发明中所描述的个实施例，用于制造丙烯的方法可包含使包含至少约10重量％丁烯的第物料流至少部分复分解以形成复分解反应产物，使复分解反应产物至少部分裂解以形成包含丙烯的裂解反应产物，以及至少部分分离丙烯与裂解反应产物以形成包含至少约80重量％丙烯的产物物料流。
