Abstract
Catalytic desulfurization process of an acid gas containing H.sub.2 S, and optionally a total quantity of at most 3% by volume of CS.sub.2 and/or COS, by contacting said acid gas and oxygen or air with a catalyst based on titanium oxide, at temperatures between 100.degree. C. and 600.degree. C. The catalyst used comprises, in addition to the titanium oxide, a sulfate of alkaline earth metal selected from Ca, Sr, Ba and Mg. Application to the desulfurization of acid gases, which in particular contain less than 15% by volume of H.sub.2 S, and therefore cannot be treated in conventional sulfur plants.
