PROCESS FOR SEPARATING LINEAR ALPHA OLEFINS FROM A STREAM CONTAINING SATURATED HYDROCARBONS, INTERNAL OLEFINS, BRANCHED OLEFINS AND LINEAR ALPHA OLEFINS

摘要

Process for treating feedstock comprising linear alpha olefins, internal olefins and saturated hydrocarbons, comprising: (a) contacting feedstock wit h a linear polyaromatic compound to form reaction mixture comprising linear polyaromatic compound-olefin adducts and saturated hydrocarbons; (b) separating the linear polyaromatic compound-olefin adducts from the saturate d hydrocarbons in the reaction mixture to form first adducted olefin stream an d saturated hydrocarbon stream; (i) dissociating said linear polyaromatic compound-olefin adducts to form linear polyaromatic compounds and olefin composition comprising alpha olefins and internal olefins; (ii) contacting olefin composition with linear polyaromatic compounds to form reaction mixtu re comprising linear polyaromatic compound-linear alpha olefin adducts and internal olefin composition; (iii) separating said linear polyaromatic compound-linear alpha olefin adducts to form linear alpha olefin adducted stream and internal olefin stream; and (iv) dissociating said linear polyaromatic compound-linear alpha olefin adducts to form linear polyaromati c compounds and linear alpha olefin composition; whereby concentration of line ar alpha olefins in linear alpha olefin composition is enriched over concentration of linear alpha olefins in olefin composition, and concentrati on of linear alpha olefins in the olefin composition is enriched over concentration of linear alpha olefins in feedstock.
