Unhappy gas-solid reactions

Liaket is on a distinguished road

I started to work with OpenFOAM very recently. I generated the geometry of a cylinder with an inlet port at the bottom of it. And mention a spherical zone at the centre of the cylinder as solid object using "setFieldDict".

My spereical object is porous and stationary. Hydrogen gas will be introduced through the inlet port and will react with with the solid sphere (iron oxide). The chemical reaction takes place isothermally and the main reaction is -

Iron-Oxide + Hydrogen = Iron + water vapour

I was trying "reactingTwoPhaseEulerFoam" solver but in that case I couldn't make the solid sphere stationary. Later with "reactingMultiphasePhaseEulerFoam" solver where introducing porosity is a problem along with no such tutorials of solid-gas reactions.

Basically I want to do a gas-solid reaction (chemical reaction and diffusion) where the solid will be porous. Can anyone help me which solver I can use or anything else which may help me in this regard?
Thanks in advance.
