Abstract A mathematical model to describe simultaneous sorption of S02, 02 and H20 in an activated carbon particle is presented in this paper. The competition for active sites of these species is taken into account by a modified Langmuir-type isotherm, which incorporates the competition of the immobile reaction product phase, H2S04. Simulations of the model are presented in terms of transient micropore filling of reactant species and product H2S04. The simulation results show that the multicomponent interactions play an important role in the sorption process. Fast diffusing species like 02 and H20 instantaneously adsorb in the micropore volume of the sorbent. In the course of simultaneous adsorption and reaction of all species in the micropore, a rollup phenomenon on the transient behavior of fast diffusing species could occur, i.e. the micropore loading of these gaseous species can overshoot the final equilibrium level. The simulation results of H2S04micropore loading are found to agree reasonably well with the experimental data.
