ABSTRACT:
A catalytic process for the production of sulphur from an acid gas containing H.sub.2 S, in which a part of H.sub.2 S is catalytically oxidized in order to form an effluent containing H.sub.2 S and SO.sub.2 in a molar ratio of 2:1 and a given quantity of sulphur, then said effluent is contacted with a CLAUS catalyst to form a further quantity of sulphur.
The catalytic oxidation of H.sub.2 S is carried out in the presence of an oxidation catalyst consisting of agglomerates comprising an active alumina thermally stabilized by at least one oxide from the group consisting of SiO.sub.2, ZrO.sub.2, the rare-earth metal oxides and the alkaline-earth metal oxides to which are associated one or more compounds of metals such as iron that promote the oxidation of H.sub.2 S.
