effect of pore size distribution on simultaneous diffusion and reaction in a porous media using pore network modeling

Pore network modeling has been extensively used for simulating various physical and chemical phenomena in porous media# in this study, a two-dimensional pore network modeling is applied to determine concentration profile inside a porous particle with reaction# this discrete model explores a reactive pellet from single site to particle# a regular disk domain pore network model with variying pore size is used# a first order reaction was considered inside pores# the concentration profile for different pore size distibution are sketched and compared to each other# the rersults revealed that the non-uniform pore networks with high dispersion of pore radius had the better performance than the uniform one#
