SO2 is oxidized under unsteady-state conditions in a fixed bed of catalyst at 20-200° and a cycle period 10-200 min. In order to simplify the process, the catalyst bed is divided into 3 sections, and fresh reaction mixt. is alternately fed between the sections. Preferably, the vol. of the central section is 0.1-0.3 times the total vol., and that of the top and bottom sections 0.45-0.35 times.
