Abstract: On the basis of the the simple kinetic model of a selective reaction that assumes two types of active sites, the performance of the dual-reactor system with the catalyst circulating between reactors under unsteady state conditions was analyzed theoretically. Main attention focuses on the analysis of the kinetic factors and technological parameters controlling catalyst unsteady state. It is shown, that the main parameters affecting the state of the catalyst are the temperature and the rate of catalyst circulation between the zones. The lecture presents the results of modeling of the oxidation of o-xylene to phthalic anhydride in a fluidized-bed reactor was simulated. The mathematical model implies that reactor was divided into two zones by a height, and the catalyst was circulated between the zones. It is shown that the regulation of the unsteady state condition of the catalyst by means of its circulation between zones allows considerable increasing the yield of the target product. 16.
