| 摘 要： | 利用8柱4区连续模拟移动床制备色谱对生物质水解液的模拟液进行了糖酸分离和回收的研究。考察了进料液流量、提余液与提取液的流量比、切换时间和洗脱剂回流比等操作条件对SMB分离性能的影响。通过试验确定了本套连续模拟移动床色谱分离装置分离糖酸的合适操作条件，在此操作条件下，提取液中糖的纯度和回收率以及提余液中酸的纯度和收率均可以达到93％。 ，成为酸快糖慢，当流过一定长度

| Abstract: | Study of separation and recovery of sugar and acid from synthetic solutions of hydrolysate by a continuous simulated moving bed ion exclusion process were made. The effects on performance of SMB process by such factors as feed volume rate, ratio of extract and raffinate, switch time and desorbent volume rate were studied. At the optimum conditions determined by experiments, purity and recovery of sugar and acid were over 93 %. |
