Abstract:
     The method for separating sugar and acid from biomass hydrolysate includes the following steps: placing the pretreated biomass hydrolysate into double-chamber bipolar membrane electrodialyzer equipment, under the condition of that the operation pressure is 20V-50V making sugar and acid separation and recovery of acid, separating time is 120-468 min. the loss rate of sugar is 2.3-3.8% and the percent recovery of acid is greater than 98%. At the same time, it can recover and reuse inorganic and organic acids in the hydrolysate, and can raise the quality concentration of sugar in the hydrolysate.
