摘要：A chromatographic separation process of a type wherein a feedstock fluidcontaining a plurality of components is supplied into a circulative chromatographicseparation system, the process comprising the steps of (i) supplying the feedstock fluidand withdrawing a fraction enriched in a component, (ii) supplying a desorbent fluid andwithdrawing a fraction enriched in another component, and (iii) circulating the fluidthrough the bed without supplying or withdrawing any fluid thereby making a mixed zonecomprising a plurality of components move, a cycle including steps (i), (ii) and (iii) beingrepeated, wherein the packed bed comprises a first unit bed packed with an adsorbent,to which the feedstock fluid is supplied, and at least one other unit bed packed with anadsorbent, and the adsorbent (e.g., ion-exchange resin) packed into the first unit bed, towhich the feedstock fluid is supplied, has a greater average particle size and/or a higherdegree of crosslinking than that packed in the at least one other unit packed bed.
