ABSTRACT:
A process and apparatus for conducting a catalytic reaction of H.sub.2 S and SO.sub.2 to elementary sulfur provides for at least two catalyst beds and that at least one part of one of the catalyst beds is operated during the reaction at below the sulfur dew point, preferably below the solids condensation point, and above the water dew point. The adsorbed and deposited sulfur is removed by heating and evaporation. At least two serially connected and interchangeable reactors are employed in preferably a single flow direction in one cycle, and the flow direction of the gas stream is reversed in a second cycle by means of a multiway fitting.
