The H2 S of the gas to be treated is oxidized to sulfur in contact with an oxidation catalyst containing at least one oxysulfide of a metal chosen from Fe, Cu, Ni, Co, Cr, Mo and W, associated with a support. in silicon carbide, operating at temperatures which are higher than the dew point of the sulfur formed in the treated gas and more particularly between 180degreC and 500degreC. Application to the elimination of the H2 S contained in gases of various origins with recovery of this H2 S essentially in the form of sulfur. |
