摘要：

The separation of mixtures of fructose, mannitol and sorbitol by continuous annular chromatography on Dowex 50W-X8 has been investigated. Distribution and mass transfer coefficients of the three substances were obtained by batch chromatography. The influence of feed concentration and flow rate on these parameters were discussed. The separation was simulated numerically and compared with experimental data. With this procedure, the separation of mixtures of fructose, mannitol and sorbitol by continuous annular chromatography (CAC) was calculated in advance, using only batch data. Additionally, the influence of rotation rate, column loading, eluent flow rate and feed concentration on the resolution of the individual peaks were investigated. With these results, the operation parameters for an industrial application of the CAC for this separation problem were determined.
