    • A regenerative process is provided for removing mercaptans contained in a gas by means of an absorbing agent based on at least one metal oxide capable of chemically fixing the mercaptans. The process comprises an absorption step to fix the mercaptans on the absorbing agent and a regeneration step for regenerating the absorbing agent laden with sulphur-containing products resulting from said fixation. The regeneration is carried out by sweeping the absorbing agent with a hot inert gas to bring the absorbing agent to a temperature between 250.degree. and 500.degree. C. and desorb the sulfur-containing products, and by contacting the absorbing agent thus treated with a gas containing free oxygen to reoxidize the absorbing agent and by cooling the reoxidized absorbing agent by sweeping with a cold inert gas.

    • 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.

    • Improved process for the production of sulphur from a gas containing H.sub.2 S, SO.sub.2, H.sub.2 and/or CO, in which the gas is caused to pass through a CLAUS catalyst in a primary catalytic stage operating at between 200.degree. and 460.degree. C. in order to form sulphur, and thereafter the sulphur contained in the reaction mixture issuing from this stage is condensed through indirect heat exchange with water to produce steam.The improved process consists in constituting at least the final eighth of the catalyst volume in this stage by a composite mass formed from a refractory oxide on which is fixed a transition metal compound, for example Co and/or Mo, and in entering into contact the gas with this composite mass at between 300.degree. and 460.degree. C. in order to oxidize H.sub.2 and CO.The energy resulting from this oxidation is recovered in the form of a supplementary quantity of steam during the sulphur condensation.
