This invention relates to a process for separating and isolating olefins from saturated hydrocarbons, and in particular, to a process for separating and isolating olefins from saturated hydrocarbons in a Fisher-Tropsch stream. There is provided a process for separating olefins from saturated hydrocarbons in a feedstock, comprising: contacting a feedstock comprising olefins and saturated hydrocarbons, such as paraffins, with a linear polyaromatic compound under conditions effective to form a reaction mixture comprising linear polyaromatic compound-olefin adducts and saturated hydrocarbons; 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; dissociating the linear polyaromatic compound-olefin adducts to form linear polyaromatic compounds and an olefin composition; and optionally separating the linear polyaromatic compound formed in step c) from the olefin composition; whereby the olefin composition is enriched in the concentration of olefins over the concentration of olefins in the feedstock and the saturated hydrocarbon stream is enriched in saturated hydrocarbons over the concentration of saturated hydrocarbons in the feedstock.

A Fisher-Tropsch composition comprising odd and even numbered olefins, said composition having an average carbon number ranging from C6 to C18, comprising:
The composition of claim 48, wherein the composition additionally comprises branched olefins in an amount of at least 10 wt. %.
A Fisher-Tropsch composition having an average carbon number ranging from C6 to C18 comprising at least two linear alpha olefin species having different carbon chain lengths within said range, inclusive, at least 50 wt. % of linear alpha olefins, said composition comprising a most predominant olefin species represented by n carbon numbers, wherein the next most predominant olefin species has either n+1 or n−1 carbon numbers;
