An H2S-containing gas and a free-oxygen-containing gas in amounts such that the molar ratio of O2 to H2S is from 0.5 to 3 are contacted, at a temperature below 200 DEG C, with a catalyst for oxidatively converting H2S into sulphur. Said catalyst consists of an activated carbon substrate incorporating a catalytic phase selected from the oxide, salt or sulphide compounds of one or more transition metals selected from V, Mo, W, Ni and Co. The amount of said catalytic phase, by weight of transition metal, represents 0.1-15 wt % of the calcined catalyst.
2135908 9421358 PCTABS00167 On fait passer le gaz renfermant de l'H2S avec un gaz renfermant de l'oxygène libre, en quantité propre à fournir un rapport molaire O2:H2S allant de 0,5 à 3 et de préférence de 0,5 à 1,5, au contact d'un catalyseur d'oxydation de l'H2S en soufre, en réalisant ledit contact à des températures inférieures à 200 ·C. Ledit catalyseur consiste en un support en charbon actif auquel est incorporée une phase catalytique choisie parmi les composés oxyde, sels ou sulfures d'un ou plusieurs métaux de transition pris parmi V, Mo, W, Ni et Co, la quantité de ladite phase catalytique, exprimée en poids de métal de transition, représentant 0,1 % à 15 % du poids du catalyseur calciné.
