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

摘要

It is related to the alkane of the present invention and any cycloalkane and/or an aromatic hydrocarbons and C5~C8 classifies in some cases that (C5~C7, C6~comprising alkene C8, C7~C8, C6~C7, C7 or C8) are from three kinds of effluents (each, a linear paraffin, a branched paraffins and branched paraffins and three minutes-branched paraffins, the compound of any cycloalkanes and/or the rich effluent of aromatic compound) for water or intermediate classification water of a chromatography process for producing. Separation method, using an isolated area to absorption. ;Method of the invention has special use in conjunction with the alkyl isomerization method on linear paraffins and branched paraffins date, particularly selectively recycles the number of carbon atoms for being greater than 7 paraffin. ;Chromatography, linear paraffin, a branched paraffins, multi-branched paraffin
