介绍了用于分离葡萄糖-果糖混合物的模拟逆流吸附系统的实验研究结果。可以在多种条件下实现有效的分离。结果表明，在稳态条件下，系统的行为可以用等效的逆流系统来很好地描述。根据分散塞流模型计算的浓度分布以及根据脉冲色谱测量计算的分散系数提供了实验分布的良好表示。或者，可以根据平衡阶段模型来描述行为，并且 McCabe-Thiele 图提供了可视化过程条件变化的影响的有用方法。色谱 HETP 约为 10 cm，对于葡萄糖和果糖而言大致相同，且与流体速度无关，表明轴向混合比传质阻力更重要。
Results of an experimental study of a simulated counter-current adsorption system for separation of glucose-fructose mixtures are presented. Efficient separation may be achieved under a wide range of conditions. It is shown that the behaviour of the system, under steady state conditions, may be well described in terms of an equivalent counter-current flow system. Concentration profiles calculated from the dispersed plug flow model, with the dispersion coefficient calculated from pulse chromatographic measurements, provide a good representation of the experimental profiles. Alternatively the behaviour may be described in terms of the equilibrium stage model and the McCabe-Thiele diagram provides a useful means of visualizing the effects of changes in process conditions. The chromatographic HETP is about 10 cm and is approximately the same for both glucose and fructose and independent of fluid velocity, suggesting that axial mixing is more important than mass transfer resistance.
