Abstract
The chromatographic adsorption separation of indene from petrochemical or synthetic feed mixtures with an Na- or K-exchanged X- or Y-zeolite and toluene, benzene, fluorobenzene or other halogen- or alkyl-substituted monocyclic aromatic desorbents. Selectivity of the separation is dependent on water content, from 1-8% (wt.), of the adsorbent.
