Elemental S is manufd. by contacting H2S-contg. gases with SO2 in the presence of a catalyst. The procedure is simplified and productivity is increased by carrying out the process with alternate change of the place of addn. and output of the reaction mixt. from the catalyst bed. At every 1-100 cycles of 1-300 min duration 1 cycle is carried out with a duration 1-10 times as great as that normally used and the initial reaction mixt. temp. at 20-200° above normal.
