A study was made of the reaction SO_2 and H_2S, varying reaction temperature, velocity of gases and volume of catalysts, for which activated alumina, bauxite, active charcoal and silica gel were used. It was found from the results that the reaction proceeded very rapidly, and at 300℃ the percentage conversion of reactants was above 96% without poisoning the catalysts. In excess of reactive gas, SO_2 or H_2S, it increased the percentage conversion of reactants. The efficiency of catalyst on the basis of surface area of it was activated alumina, bauxite, active charcoal and silica gel was much more inferior than them.
