COMPARATIVE STUDY OF ZEOLITE AND RESIN ADSORBENTS FOR THE SEPARATION OF FRUCTOSE-GLUCOSE MIXTURES.

Abstract

The kinetics and equilibria of sorption of fructose and glucose on Ca**2** plus ion-exchange resins and Ca**2** plus -exchanged zeolite adsorbents have been studied experimentally by pulse and step chromatographic methods. The best of the resin adsorbents shows a higher equilibrium separation factor than CaY zeolite, but this advantage is largely offset by the greater resistance to mass transfer. Under practical operating conditions in a simulated countercurrent chromatographic separation unit, the resin and zeolite adsorbents show little difference in performance, although the flow conditions required for the two adsorbents are significantly different.
