Abstract
A process is provided involving the production of elemental sulfur via the Claus reaction of hydrogen sulfide and sulfur dioxide. A gas feedstream containing H.sub.2 S and SO.sub.2 is passed through solid catalyst beds below the sulfur dew point to thereby deposit the sulfur formed on the catalyst bed. Sulfur is then removed from the catalyst bed by passing heated effluent gas from another catalyst bed through the first bed to vaporize the deposited sulfur and thereby regenerate the first catalyst bed. Reactor apparatus especially suitable for practicing this process is also provided.
