Abstract: Provided here are methods for propene production facilitated by an adsorption separation unit that is integrated downstream or upstream of a metathesis reactor. A method includes supplying a C4 feed stream to a metathesis reactor to produce a metathesis product stream containing ethene, propene, C4 paraffins, C4 olefins, C5 olefins, and C6 olefins, supplying the metathesis product stream to a first separation column to produce a light product stream containing ethene and propene and a C4+ stream containing C4 paraffins, C4 olefins, C5 olefins, and C6 olefins, supplying the C4+ stream to a second separation column to produce a C5-C6 olefin stream containing C5 olefins and C6 olefins and a mixed C4 stream containing C4 paraffins and C4 olefins, and supplying the mixed C4 stream to an adsorption separation unit to produce a C4 paraffin stream and a C4 olefin stream, which is recycled to the metathesis reactor.
