Abstract
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.
