ABSTRACT An adsorptive separation process is disclosed for separating para-aromatic isomers from a hydrocarbon feed containing a mixture of aromtic isomers, using a crystalline aluminosilicate adsorbent which has been treated with an alkyl amine preferably an alkyl amine hydrochloride. The alkyl amine treatment substantially increases the selectivity of the adsorbent for the para-xylene isomer, relative to the heavy desorbent p-DEB, thereby improving the efficiency of the separation process.
