The use of hierarchically organized nanoporous materials has
proven to be well suited for counteracting transport hindrance
in micropores and the resulting reduction in their technological
performance. As a typical example, we consider materials with
the structure of mesoporous zeolites, where a microporous
continuum is traversed by a network of mesopores. Mass
transfer in such material has recently been shown to be
effectively quantitated by application of the two-region
approach of diffusion (the “Kärger model”). It operates with the
diffusivities in the two pore spaces, their relative occupations
and the mutual exchange rates as the only free parameters. In
the present paper, the validity of this approach for the
combined consideration of mass transfer and catalytic conversion
in such materials will be confirmed by comparison with
the outcome of kinetic Monte Carlo simulations.
