PROCEDE POUR OXYDER DIRECTEMENT EN SOUFRE, PAR VOIE CATALYTIQUE ET EN PHASE VAPEUR, L'H2S CONTENU A FAIBLE TENEUR DANS UN GAZ

摘要

The invention concerns a method whereby the gas to be treated is oxidised in sulphur by being contacted with an oxidation catalyst containing at least an oxysulphide of a metal selected among Fe, Cu, Ni, Co, Cr, Mo and W, associated with a silicon carbide support, by operating at temperatures, which are higher than the dew point of the sulphur formed in the treated gas and more specifically ranging between 180 DEG C and 500 DEG C. The invention is useful for eliminating H2S contained in gases of various origins with recovery of said H2S essentially in the form of sulphur.
