本文介绍了一种多组分进料连续色谱分离装置。它由磁稳定流化床（MSB）组成，其中床固体横向流动到流化流体。进料的可吸附组分沿两个方向移动;流化载体流体移动到床表面，固体穿过床移动到取决于其吸附特性的不同位置。使错流MSB色谱仪具有吸引力的特征是能够在单个容器中连续地将进料混合物分离成多种产品，而无需移动机械部件。MSB非常适合色谱操作。流体和固体在活塞流中移动，并且压降限于每单位床面积的固体重量，与颗粒尺寸和流体通过量无关。使用示踪气体，操作的错流MSB色谱仪已被证明。增加错流床的高度已被证明可以改善…
Abstract A device for continuous chromatographic separation of multicomponent feeds is described. It consists of a magnetically stabilized fluidized bed (MSB) in which bed solids move crossflow to the fluidizing fluid. Adsorbable components of the feed move in two directions; with the fluidizing carrier fluid to the bed surface, and with the solids across the bed to different positions depending on their sorption characteristics. The features that make the crossflow MSB chromatograph attractive are the ability to continuously separate feed mixtures into multiple products in a single vessel with no moving mechanical parts. The MSB is ideally suited for chromatographic operation. The fluid and solids move in plug flow, and the pressure drop is limited to the weight of solids per unit bed area, independent of the particle size and fluid throughput. Using tracer gases, the operation of a crossflow MSB chromatograph has been demonstrated. Increasing the height of the crossflow bed has been shown to improve the...
