Abstract
AbstractThe adsorptive separation of fructose from glucose has been carried out in a simulated counter‐current chromatographic system using Zerolit‐25SCR14 ion exchange resin in Ca++ form as the adsorbent. Rate and equilibrium constants have been determined from chromatographic retention time measurements. The performance of a simulated counter‐current system comprising ten identical columns connected in series has been investigated and it is shown that the behaviour of such a system may be approximately represented by a simple McCabe–Thiele model. The HETP in the counter‐current system is higher than would be expected for an ideal plug flow system, showing that axial mixing is important. The McCabe–Thiele analysis may be easily extended to a four section ‘Sorbex’ system and a preliminary assessment of the performance of such a unit is made on the basis of the kinetic and equilibrium parameters derived from the experimental study.
