Abstract
The invention concerns catalysts for treating residual gases, containing hydrogen and carbon derivatives of sulphur, by the Claus reaction. These catalysts have a specific area of at least 80 m.sup.2 /g and essentially comprise active alumina and a titanium compound. They enable carbon compounds of sulphur to be destroyed and the Claus reaction proper to be obtained with good yields.
