摘　　要：利用顺序式模拟移动床色谱(SSMB)分离设备,对木糖母液中回收木糖、阿拉伯糖和葡萄糖的两种分离工艺进行比较研究。结果表明:两组分分离工艺中木糖、阿拉伯糖纯度分别达86.30%,88.41%,回收率为85.20%,89.26%;三组分分离工艺中木糖、阿拉伯糖纯度分别达77.73%,79.94%,回收率为82.00%,87.00%。两种分离工艺各具优势,均可有效解决木糖母液低效回收处理的难题,具有分离连续化、运行自动化和产品均一等优点。The two kinds of sepatation process for the xylose mother liquor of xylose,arabia sugar and glucose was studied which used the sequential simulated moving bed(SSMB)chromatographic separation equipment.In the optimal separation conditions of the separation process for two components,the purity of xylose and arabia sugar reached 86.30%and 88.41%,and recovery rate reached 85.20%and 89.26%.During the separation process of the three components,the purity of xylose and arabia sugar reached 77.73%and 79.94%,and the recovery rate reached 82.00%and 87.00%,respectively.Xylose mother liquor recovery processing was very difficult,the problem can be effectively solved with the two kinds of separation process which had the advantages of continuous separation,operation automation and products homogenization.
