The heterogeneous transient model of a fixed - bed reactor packed with vanadium catalyst

for catalytic oxidation of SO2 and operating in a flow direction switched periodically was developed. Computation results showed that autothermal oxidation of low concentration SO2 is feasible. The effects of important parameters on the performances of the reactor operating in this mode were numerically studied. It is noticed that time averaged conversion and temperature at the hot - spot are rather sensitive to the variation of the composition and flow rate of feed. This qualitative conclusion should be considered in the design of a commercial reactor in order to keep stable operation.
