"Axial dispersion in the single pellet-string arrangement of a chromatographic column (SPSC) packed with 15 types of pellets with various shapes was studied. Both non-porous cylindrical pellets and non-spherical porous pellets with pores blocked by a liquid (Porofil) were used. For different tracer- and carrier-gases (carrier-gases: N2, H2; tracer-gases: H2, He, N2, Ar) comparable dependencies of Bodenstein numbers, Bo, versus the product of Reynolds and Schmidt numbers, ReSc, were obtained. Tracer dispersion due to extra column effects was eliminated via convolution of column responses for two column lengths. An interpolation equation for different pellet shapes was proposed. The pellet shape is characterized through pellet sphericity, ?, and the pellet/column diameter ratio, dp/dc. The effectiveness of axial dispersion correlations was confirmed for sphericity 0.427-0.89 and the pellet/column diameter ratios 0.35-0.87." . . . "[5622A46FA916]" . "Chemical Engineering Journal" .
