A method based on experimental breakthrough curves for quickly evaluating adsorbents for a defined separation in terms of selective volume, capacity, selectivity and productivity is demonstrated under the conditions of the Parex process. Fixed-bed experiments are carried out in order to assess a barium-exchanged faujasite-type zeolite as adsorbent for the separation of p-xylene from its isomers.
