In a fluidized bed reactor, catalyst particles move continuously along a reactor height in the reaction medium with varying composition of reagents. Under the influence of the reaction mixture each particle permanently changes its properties being in unsteady state with respect to the surrounding reagents. This paper considers the effect of the unsteady state of the catalyst in a fluidized bed reactor for the example of SO2 oxidation. A mathematical model taking into account the unsteady state of the catalyst is developed. To model particle transfer, an equation that defines the density of distribution of catalyst particles depending on parameters determining their state was used. The results obtained using steady state and unsteady state kinetic models are essentially different. Optimization of the temperature profile to give maximum efficiency of the reaction was performed.
