Separation of simple sugars by selectivity inverted parametric pumping

An alternative process to separate the isomeric mixture of frutose and gluc ose is presented. A laboratory study of a two-column, selectivity inverted, direct-mode parametric pump is reported. An anionic resin in carbonate for m and a cationic resin in calcium form are used as adsorbents for the colum ns. The experimental results show that it is possible to simultaneously obt ain separation and concentration with this system. A kinetic model assuming linear equilibrium, intraparticle pore diffusion, and axial dispersion is proposed and solved. The model solutions are compared with experimental res ults, and the comparisons indicate good prediction capabilities.
