Glucose-fructose equilibria on Dowex Monosphere 99 CA resin under overloaded conditions - Saska, M.; Clarke, S.J.; Di Wu, M.; Iqbal, K. (Elsevier)
Matching of the numerical simulation of the band propagation with experimental elution profiles of glucose and fructose was used to obtain the adsorption isotherms of glucose and fructose at 70^oC on Dowex Monosphere 99 CA resin (Dow Chemical), an adsorbent widely used in the high-fructose corn syrup (HFCS) industry. The respective distribution coefficients, K"G = 0.245 + 0.0051c"G + 0.003c"F and K"F = 0.47 + 0.007c"G + 0.0049c"F, are non-linear and dependent on the concentrations of both sugars. Contrary to some previous reports, the height equivalent to a theoretical plate of glucose (2.7 cm) was less than that of fructose (3.5 cm). The ideal chromatographic model with the band spreading originating in an implicit way from the numerical integration of the appropriate partial differential equation was found suitable to fit the coupled, non-linear behavior of glucose-fructose mixtures and can be a useful tool for modelling and optimization of the industrial simulated moving bed HFCS process.
