AbstractAxial dispersion coefficients of squalene, benzoic acid, and oleic acid were measured in packed beds using supercritical carbon dioxide as a solvent over the temperature range 313-333 K, pressure range 100-300 bar, and Reynolds number range 2-80. Measurements were performed under both horizontal and vertical flow conditions, using a variety of particle sizes, bed diameters, and bed lengths. The axial Peclet numbers obtained for small particles (1 mm) could be satisfactorially predicted by literature correlations.
