Abstract
Catalytic process for producing sulphur from H.sub.2 S-containing acid gas wherein the acid gas is subjected to a catalytic oxidation of CLAUS stoichiometry and to a catalytic CLAUS reaction phase with deposition of sulphur on the catalyst with periodic regeneration of the sulphur-laden catalyst and cooling of the regenerated catalyst. The gas used for the regeneration and for the cooling is tapped from the acid gas supplied to the catalytic oxidation and the gas issued from the regeneration is reintroduced into said acid gas after separation of the sulphur contained therein. The process is particularly applicable to the treatment of acid gases having a low H.sub.2 S content.
