- Аннотация: The frontal adsorption dynamics with the convex adsorption isotherm at a stage of parallel transfer, was numerically simulated. The change with time in the mean adsorption values ac in the adsorbent layers of short length ΔL and corresponding concentrations cΔL at the outlet from ΔL was calculated. Zeldovich"s equality, which suggests that the ratio of cΔL to ac is equal to the ratio of the inlet fluid phase concentration to the amount adsorbed at equilibrium, is fulfilled at ΔL → 0 over the interval of relative concentrations from 10–4 to 1. This indicates that Zeldovich"s equality is fulfilled as local at any limiting stage of mass transfer. The nonequilibrium dynamics of adsorption always has the finite ΔL value at which the calculated cΔL and ac values approximately coincide with the a and c values of the equilibrium adsorption isotherm.
