Abstract: Systems and methods for metathesizing C4 streams to produce chemical feedstocks, including light olefins, such as ethene and propene. A method provided herein for producing ethene and propene includes the steps of metathesizing a but-1-ene-rich C4 stream to produce a metathesis product stream. The method includes the steps of separating the metathesis product stream into a C2-C3 olefin stream and a C4+ olefin stream. The method includes the steps of separating at least a C4 olefin stream of the C4+ olefin stream, the C4 olefin stream forming a portion of the but-1-ene-rich C4 stream prior to metathesis. The method includes the steps of separating at least the C2-C3 olefin stream into an ethene product stream and a propene product stream.
