Abstract (en)
[origin: WO2020260027A1] The invention relates to a process for separating glucose in the liquid phase from a mixture of C5 and C6 sugars comprising at least xylose and glucose, by adsorbing the glucose on a zeolite adsorbent which is based on FAU zeolite crystals with a Si/Al atomic ratio strictly greater than 1.5 and which comprises barium, in which process: - the mixture is brought into contact with the adsorbent in liquid chromatography to obtain a xylose-enriched liquid phase and a glucose-enriched adsorbed phase; - the xylose-enriched liquid phase is recovered, and the phase adsorbed on the adsorbent is desorbed by means of a desorption solvent in order to recover the glucose.
