Numerical study on the effect of stacking on the apparent reactivity in fixed bed reactors


                      Extrudates catalyst particles



Encadré par : CLIMENT Eric et ROLLAND Mathieu  (INP et IFPEN)

Most catalytic and petrochemical reactions are operated with fixed bed reactors. In these reactors, catalyst pellets are generally randomly stacked in a large cylindrical vessel and the reactants, usually gas and liquid, are flowing through the bed to react inside the catalyst pellets. The aim of this project is to perform numerical simulations to study the effect of stacking on the mass transfer and the apparent reactivity in those pellets .The used tool is COMSOL-Multiphysics 3.5a.
