This invention relates to a process for separating and isolating saturated hydrocarbons from olefins, and in particular, to a process for separating and isolating saturated hydrocarbons from olefins in a Fisher-Tropsch stream. There is provided a process for separating olefins from saturated hydrocarbons in a feedstock, comprising: a) 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; b) 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; c) dissociating the linear polyaromatic compound-olefin adducts to form linear polyaromatic compounds and an olefin composition; and optionally d) 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 process for treating a feedstock composition comprising linear alpha olefins, internal olefins, and saturated hydrocarbons, comprising:
A process for contacting a linear polyaromatic compound with a feedstock composition comprising linear alpha olefins, internal olefins, and saturated hydrocarbons, separating the olefins from the saturated hydrocarbons in the feedstock composition to form an olefin composition and a saturated hydrocarbon stream, subsequently contacting a linear polyaromatic compound with the saturated hydrocarbon stream comprising linear alpha olefins and internal olefins, and separating the internal olefins and linear alpha olefins from the saturated hydrocarbons in the saturated hydrocarbon stream to form a second saturated hydrocarbon stream and a second olefin composition, whereby the concentration of each of internal olefins and linear alpha olefins in the second olefin composition is enriched over the concentration of each of internal olefins and linear alpha olefins in the feedstock and in the olefin composition.
A composition comprising odd and even numbered olefins, said composition having an average carbon number ranging from C5 to C20, comprising:
A 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, where the composition has 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;
