PCT No. PCT/FR97/00565 Sec. 371 Date Feb. 13, 1998 Sec. 102(e) Date Feb. 13, 1998 PCT Filed Mar. 28, 1997 PCT Pub. No. WO97/37750 PCT Pub. Date Oct. 16, 1997The invention relates to a process for the direct oxidation of sulphur compounds into elemental sulphur and/or into sulphates at a temperature below 200 DEG C., in which a supported catalyst whose catalytically active phase comprises copper is used, the copper element being present in a content of at least 2% by weight relative to the catalyst and of at least 15 by weight relative to the sum of the elements of the catalytically active phase. The use of a catalyst of this type ensures a high conversion of the H2S while at the same time minimizing the conversion into SO2.
