A mathematical model was proposed to describe the mass-transport phenomena in packed column with spherical composites which are consisted of the outer shells and the inner spheres. Any contact resistance between the former and the latter was assumed to be negligible. The first and the second moments were derived by means of the moment generating properties of Laplace transform.
