ABSTRACT:
A process for separating a ketose from a feed mixture comprising a ketose and an aldose which process comprises contacting the mixture with an adsorbent comprising a X zeolite containing one or more selected cations at exchangeable cationic sites thereby selectively adsorbing a ketose from the feed mixture and thereafter recovering the ketose. Preferably, the ketose will be recovered by desorption from the adsorbent with a desorbent material.
