ABSTRACT:
A process for continuously separating, in liquid phase, fructose from a liquid feed mixture of sugars containing essentially fructose and glucose by contact with a solid sorbent of zeolite. The process utilizes a simulated countercurrent flow system wherein a liquid stream flows through serially and circularly interconnected desorption, rectification and sorption zones each zone being divided into a plurality of sections. In the zones water as desorbent is introduced into the desorption zone, the liquid feed mixture of sugars is introduced into the sorption zone, a desorption effluent is withdrawn from the desorption zone and a raffinate effluent is withdrawn from the sorption zone, and all of the points of introduction and withdrawal of the liquids are simultaneously shifted, one section at a time at predetermined intervals of time, in a downstream direction.
