Abstract:
A process for separating olefins from saturated hydrocarbons in a feedstock, comprising:a) contacting a feedstock comprising olefins and saturated hydrocarbons with a linear polyaromatic compound having at least three fused aromatic rings under conditions effective to form a reaction mixture comprising linear polyaromatic compound-olefin Diels Alder adducts and saturated hydrocarbons; b) separating the linear polyaromatic compound-olefin adducts from the saturated hydrocarbons in the reaction mixture to form a saturated hydrocarbon stream and an adducted olefin stream; c) dissociating the linear polyaromatic compound-olefin adducts to form linear polyaromatic compounds and an olefin composition, whereby the olefin composition is enriched in the concentration of olefins over the concentration of olefins in the feedstock.
