✦ Synopsis
A mathematical model is derived describing the multicomponent mass transport in a porous product layer with accompanying gas-solid reaction (the solid is initially nonporous). Making use of the derived model the overall conversion profiles are determined. A comparison of profiles is made for all the mass transport modes considered. The analysis shows that the effect of mass transport mechanism in a porous product layer on the gas-solid process can be quite considerable and depends on the kinetic and itoichiometric parameters and pellet shape.
