A new approach to modeling the catalytic processes in column apparatuses in cases of physical and chemical adsorption mechanism is presented. Numerical analysis shows that average concentration model, where the radial velocity component is zero (in cases of a constant velocity radial non-uniformity along the column height), can be used in cases of an axial modification of the radial non-uniformity of the axial velocity component. The use of experimental data, for the average concentration at the column end, for a concrete process and column, allows obtaining the model parameters related with the radial non-uniformity of the velocity. These parameter values allow the use of the average concentration model for modeling of different processes.
