In the 1-D format, the problem of nonstationary isothermal local distribution of a diffusing single-species substance in successively located axisymmetric spherical regions of a granule with different permeabilities of macro- and micropores is formulated. The initial-boundary value problem for a system of differential equations of parabolic type with a boundary condition of the first kind on the outer boundary of a granule and of the fourth kind on the boundary of conjugation of the domains is integrated numerically. A computational experiment has demonstrated the influence of the regions permeability and the dislocation of the boundary between them on the kinetics of material transport.
