Novel applications of continuous annular chromatography: Separation of sugars
Abstract
Continuous chromatographic separations of fructose-glucose-sucrose mixtures have been investigated experimentally in a laboratory-scale continuous annular chromatograph using Ca-exchanged Dowex 50W-X8 resin as adsorbent. Comparative chromatographic separation studies have also been conducted for the system using a conventional fixed-bed column packed with the same resin. Complete resolution of fructose-glucose mixtures could be obtained both in a 60 cm-long continuous annular chromatograph and in a conventional column of the same length with sugars feed concentration up to 200 g/L. In the four-component mixture blue dextran (higher molecular weight saccharide), sucrose, glucose and fructose complete rsolution of all species except sucrose-glucose under the relatively mild separating conditions tested. The experimental results have been analyzed in terms of approximate linear chromatographic theories for fixed and rotating beds. Bed properties and equilibrium and mass transfer parameters used in the model were obtained through independent experiments. With these parameters a good fit to the experimental results was obtained. Differences in feed mixtures and dispersion characteristics contribute to the minor offset between fixed bed and continuous chromatograph results. 21 refs., 12 figs., 3 tabs.
