SO2 is oxidized to SO3 in a fixed-bed catalyst under nonsteady-state conditions with a moving reaction zone and reaction mixt. temp. of 20-200° at the inlet to the catalyst bed. To simplify oxidn. and reduce temp. gradients in the reaction vol. during treatment of gas contg. 1-12% SO2, oxidn. takes place with the reaction zone const. moving in one direction in the catalyst bed divided into sections with the outlet of the last one joined to the inlet of the first. The fresh reaction mixt. is injected and the reacted mixt. is removed in the spaces between sections.
