ABSTRACT:
An improved process for separating normal paraffins from a feed stream containing a mixture of normal paraffins and isoparaffins. The general process comprises the steps of contacting the feed stream with an adsorbent comprising a crystalline aluminosilicate thereby adsorbing normal paraffins and subsequently contacting the adsorbent with a desorbent material to remove the adsorbed normal paraffins. The improvement resides in a method of fractionating and recycling a desorbent material for re-use in the process in a manner that reduces total fractionation energy requirements. The method is particularly suitable when two desorbent materials are used in the process.
