Abstract:
A process for treating a feedstock composition comprising linear alpha olefins, internal olefins, and saturated hydrocarbons, comprising:a) contacting the feedstock composition with a linear polyaromatic compound in a first reaction zone under conditions effective to form a reaction mixture comprising linear polyaromatic compound-olefin adducts and saturated hydrocarbons;b) separating the first linear polyaromatic compound-olefin adducts from the saturated hydrocarbons in the reaction mixture to form an adducted olefin stream and a first saturated hydrocarbon stream enriched in the concentration of saturated hydrocarbons over the concentration of saturated hydrocarbons in the feedstock composition;si) contacting the saturated hydrocarbon stream with a polyaromatic compound in a second reaction zone under conditions effective to form a reaction mixture comprising second linear polyaromatic compound-olefin adducts and saturated hydrocarbons;sii) separating the second linear polyaromatic compound-olefin adducts from the saturated hydrocarbons in the reaction mixture to form a second adducted olefin stream comprising the second linear polyaromatic compound-olefin adducts, and a second saturated hydrocarbon stream enriched in the concentration of saturated hydrocarbons over the concentration of saturated hydrocarbons in the first saturated hydrocarbon stream;siii) dissociating the second linear polyaromatic compound-olefin adducts to form linear polyaromatic compounds and a second olefin composition comprising alpha olefins and internal olefins enriched in the concentration of alpha olefins and internal olefins over each of their concentrations in the first saturated hydrocarbon stream.
