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