Ferrite catalysts with high intraparticle pore volume and surface area are frequently used in the oxidative dehydrogenation of butylene. Whether the non-inclusion of intraparticle transfer limitation in fixed-bed reactors for oxidative dehydrogenation over ferrite catalysts in previous studies is appropriate remains unclear. In this study, we attempt to verify this process using a multi-scale modeling technology. The multi-scale model consists of a porous medium model and a single particle model under the oxidative dehydrogenation condition. This model can predict the influences of intraparticle transfer on the main component distributions in reactors and demonstrate that the intraparticle transfer limitation is obvious.
