A method has been developed of evaluating the transport parameters of porous catalysts using the mean transport pore model (MTPM). The method has been based on combining results of permeation and diffusion measurements while taking into account the different reliability of results of both methods. The approach has been applied to six catalysts for the conversion of water gas with monodisperse pore distribution. Various simple gases have been used to test the MTPM, i.e. the independence of transport parameters on experimental conditions. The results have pointed at the shortcomings of estimating the mass transport in porous structures using pore distribution determined by conventional methods.
