H2S in a process gas is oxidised to sulphur by contacting it with an oxidation catalyst consisting of at least one metal and particularly a transition metal compound, or of the corresponding elemental metal, in combination with a silicon carbide carrier, at temperatures which, depending on the embodiment, may be higher than or well below the dew point of the resulting sulphur. The method is useful for removing H2S from various gases and recovering the H2S essentially in the form of sulphur.
L'H2S du gaz à traiter est oxydé en soufre au contact d'un catalyseur d'oxydation consistant en au moins un composé d'un métal, notamment métal de transition, ou en le métal correspondant à l'état élémentaire, associé à un support en carbure de silicium, en opérant à des températures qui, selon la mise en oeuvre retenue, peuvent être supérieures ou bien inférieures au point de rosée du soufre formé. Application à l'élimination de l'H2S contenu dans des gaz d'origines diverses avec récupération de cet H2S essentiellement sous la forme de soufre.
