摘要：

Effective axial dispersion coefficients D-ax in packed beds were measured by the chromatographic method at 313.2 K both for supercritical CO2 in the pressure range from 11 to 35 MPa and for organic solvents at atmospheric pressure. The D-ax values were correlated with the Reynolds number, Schmidt number, binary diffusivity and bed void fraction. The correlation was consistent for all solvents, irrespective of pressure.
