Abstract: The paper presents a mathematical model of steady-state internal diffusion in a catalyst grains in fixed-bed reactors. A key feature and scientific contribution of this work is the account of the reversible reaction stage based on the submitted concept of the reaction-diffusion number. By this, the characteristics of the transfer process in batch and flow-through apparatus are considered. The results of calculations carried out on the basis of the model have been also presented and a brief qualitative analysis has been given.
