摘要
利用模拟移动床 (SMB)连续色谱技术分离木糖醇母液中的木糖和木糖醇组分 .在平衡理论的框架下 ,提出了使用基于相应的真实移动床 (TMB)的简化数学模型研究各进料液和产品流出液的流量等操作参数的变化对SMB分离性能 (以纯度和收率作为性能指标 )影响的方法 ,并采用该方法进行了操作条件寻优仿真 ,取得了满意结果 .在实验室SMB分离设备上 ,基于此最佳操作条件所得到的木糖和木糖醇产品液纯度和收率均达到 1 0 0 % .
The simulated moving bed (SMB) chromatographic technique has been used to separate the xylitol mother liquor into xylose and xylitol component. In the frame of equilibrium theory, characterized by purity and recovery, a new method is presented to study the influences of inlet and outlet flow rate upon the SMB performance by using a simplified mathematical model of the corresponding true moving bed (TMB). Then, the operation conditions were optimized by computer simulation with the method, and the satisfaction results were obtained. By using a SMB equipment of our labor, the 100% purities and recoveries in the xylose and xylitol product liquor were obtained according to the optimized operation conditions.
