In order to determine the yield of a given gas reaction catalyzed by a so‐called reconstructed porous catalyst as a function of the operation conditions, two processes have to be simulated: the reaction on the catalytically active walls and the diffusional material transport within the pore space of the catalyst. In this contribution, the diffusional material transport of a pure gas through a capillary of constant quadratic cross section under steady‐state conditions without the influence of a chemical reaction is discussed and the procedure tested for use in computer‐aided catalyst design.
