A convection-diffusion model is obtained in the approximations of the mechanics of continua, where the mathematical point is equivalent to the medium elementary volume, which is sufficiently small with respect to the column volume and at the same time sufficiently large with respect to the intermolecular volumes of the medium. On this base convection–diffusion type models are created, which permit to be made qualitative analysis of the process. They are a base of average concentration models, which are used for the quantitative description of the catalytic processes in the column apparatus. The model parameters are obtained, using experimental data. Keywords—catalysis, column, mechanism, modeling, parameters.
