PROCESS FOR SEPARATING OLEFINS FROM SATURATED COMPOUNDS

摘要

Process for treating feedstock comprising saturated hydrocarbons, internal olefins, and alpha olefins, comprising: (a) contacting feedstock with a linear polyaromatic compound to form reaction mixture comprising first linear polyaromatic compound-olefin adducts and saturated hydrocarbons; (b) separating first olefin adducts from the saturated hydrocarbons in the reaction mixture to form first olefin adduct stream and first saturated hydrocarbon stream; s(i) contacting at least a portion of first saturated hydrocarbon stream with a linear polyaromatic compound to form a reaction mixture comprising second linear polyaromatic compound-olefin adduct and saturated hydrocarbons; s(ii) separating said second olefin adduct from reaction mixture to form second olefin adduct stream and second saturated hydrocarbon stream, wherein concentration of saturated hydrocarbons in second saturated hydrocarbon stream is enriched over concentration of saturated hydrocarbons in first saturated hydrocarbon stream, and concentration of the saturated hydrocarbons in first saturated hydrocarbon stream is enriched over concentration of saturated hydrocarbons in feedstock; s(iii) optionally dissociating second olefin adducts to form first linear polyaromatic compounds and first olefin composition; s(iv) optionally separating linear polyaromatic compound from first olefin composition; and composition produced by said process.
