【 摘 要 】

A mathematical model has been built and a simulation has been carried out for the isoparaffins dehydrogenation reaction in a fluidized bed reactor using the example of isobutane dehydrogenation to isobutylene. The parameters for the model construction are determined on the basis of experimental data. Conducted numerical studies with the selection of the average diameter for the polydisperse catalyst. The calculations were performed for cases of monodisperse and bidisperse composition of particles. The analysis of the influence of the fine particle presence on the yield of the reaction product in the numerical simulation has been carried out.
