This study presents a 2D computational fluid dynamic (CFD) to investigate the performance of silica membrane reactor (MR) during isobutane dehydrogenation reaction for hydrogen and isobutene production. The proposed CFD model provides the local information of velocity and component concentration for the driving force analysis. The validation of model results was carried out by experimental data and a good agreement between model results and experimental data was achieved. In MR model, a commercial Pt/Al2O3 catalyst in reaction zone was considered. The effects of some important operating parameters such as reaction temperature and reaction pressure on the performance of silica MR were studied in terms of isobutane conversion and hydrogen recovery. The CFD results showed that the silica MR during isobutane dehydrogenation reaction presents higher performance in terms of isobutane conversion and hydrogen recovery with respect to Packed-bed reactor (PBR), in all the studied cases.
