Detailed mathematical models, pore or grain based, describing diffusion, reaction, and pore structure evolution in pellets of porous solids are used to simulate, along with a macroscopic reactor design model, the transient phenomena that take place during desulfurization of coal gas in fixed‐bed reactors of pellets of metal oxide sorbents. Our computer simulation results show that the form of the pore‐ or grain‐size distribution strongly influences the predictions of the overall reactor design model.
