Process for separating linear alpha olefins from a crude stream containing saturated hydrocarbons, internal olefins, branched olefins, and linear alpha olefins

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 a first adducted olefin stream and a saturated hydrocarbon stream;
• oi) dissociating linear polyaromatic compound-olefin adducts in the first adducted olefin stream to form linear polyaromatic compounds and an olefin composition comprising alpha olefins and internal olefins;
• oii) contacting the olefin composition with linear polyaromatic compounds in an AO reaction zone under conditions effective to form a reaction mixture comprising linear polyaromatic compound-linear alpha olefin adducts and an internal olefin composition;
• oiii) separating the linear polyaromatic compound-linear alpha olefin adducts from the reaction mixture obtained from the AO reaction zone to form a linear alpha olefin adducted stream and an internal olefin stream;
• and
• oiv) dissociating the linear polyaromatic compound-linear alpha olefin adducts in the linear alpha olefin adducted stream to form linear polyaromatic compounds and a linear alpha olefin composition;
• whereby the concentration of linear alpha olefins in the linear alpha olefin composition is enriched over the concentration of linear alpha olefins in the olefin composition, and the concentration of linear alpha olefins in the olefin composition is enriched over the concentration of linear alpha olefins in the feedstock.
