Abstract

Process and apparatus for catalytic oxidation of sulfur dioxide in several steps (1, 1') by directing hot, sulfur dioxide bearing gases through several successive solid catalyst beds (5) and by cooling (6) the gases between the steps. In order to prevent the catalyst bed (5) from becoming clogged, the hot, sulfur dioxide bearing gases are directed upwards from below through the topmost catalyst bed (5), and the dust which has accumulated on the floor (11) of the chamber (1) is removed.
