Abstract:
A process for producing an olefin product enriched in trans-isomers from a mixed olefin feedstock comprising cis-isomer olefins and trans-isomer olefins comprising the steps of:a) contacting the mixed olefin feedstock with a linear polyaromatic compound under conditions effective to form a reaction mixture comprising linear polyaromatic compound-olefin adducts; b) separating the linear polyaromatic compound-olefin adducts from the unreacted olefins in the reaction mixture to form an adduct stream and an unreacted olefin stream; c) dissociating the linear polyaromatic compound-olefin adducts in the adduct stream to form linear polyaromatic compounds and an olefin composition enriched in trans-isomer compared to the mixed olefin feedstock; d) separating the linear polyaromatic compound formed in step c) from the olefin composition.
