ABSTRACT:
Sucrose which is found in molasses such as beet molasses or cane molasses may be selectively extracted therefrom by passing an aqueous solution of the molasses over a solid adsorbent such as activated carbon. The sucrose will be selectively adsorbed thereon and separated from the betaine and mineral salts, specifically potassium chloride, in the molasses. The sucrose is then removed from the adsorbent by treatment with a desorbent material comprising an alcohol. In applying the simulated moving bed countercurrent flow system to this separation, the presence of the alcohol in the adsorbent will seriously impede the adsorption of the sucrose. The present invention incorporates a water flush stream into such a system in a unique manner which, among other things, precludes the presence of alcohol in the adsorption zone.
