    AnnotationTwo models of a porous body, a 3D replica obtained by stochastic reconstruction and a random pore network, were evaluated with reference to the effective diffusivity of gases. The stochastic reconstruction technique employs the limited morphological information that was extracted from images of 2D cuts through the porous medium. The pore network was derived in such a way that the total porosity, pore-size function, mean coordination number, and mercury intrusion curve agreed well with experiment. A simulator of steady diffusion flow in the pore network slightly overestimated the effective diffusivity while the direct calculation of the effective diffusivity by exploiting random-walk simulation in the 3D re
