ABSTRACT:
The separation of normal paraffins from non-normal hydrocarbons wherein the paraffins have from about 10 to about 35 carbon atoms per molecule, using a molecular sieve adsorbent having an effective channel diameter of about 5 angstroms wherein an improvement in the process comprises passing a non-normal hydrocarbon input stream into the adsorption zone at adsorption conditions to promote the selective adsorption of the straight chain hydrocarbon constituents of the feed material in contact with the adsorbent in preference to the lighter straight chain hydrocarbon constituents of the desorbent material also in contact with adsorbent.
