PROCESS FOR CHROMATOGRAPHIC SEPARATION OF A C5~C8 FEED OR AN INTERMEDIATE FEED INTO THREE EFFLUENTS RESPECTIVELY RICH IN STRAIGHT CHAIN MONO-BRANCHED AND MUTI-BRANCHED PARAFFINS

摘要

The present invention relates to a C5 to C8 classifier or an intermediate class (C5 to C7, C6 to C8, C7 to C8, or any combination thereof) containing a paraffinic hydrocarbon and optional naphthenic hydrocarbons and / or aromatic hydrocarbons, Three branched effluents (straight chain paraffins, unbranched paraffins and branched and paraffinized paraffins, arbitrary naphthenic compounds and / or aromatics rich effluents, respectively) from the distillation column (C8, C6 to C7, C7 or C8) The present invention relates to a chromatographic separation method. The separation method uses a separation zone that performs adsorption.;The process of the present invention has a specific use in combination with a straight-chain paraffin and a monohydrated paraffin, in particular a hydroisomerization process, which selectively recycles paraffins having 7 or more carbon atoms.
