Patent
CA 2282668
The invention concerns a method wherein the H2S of a gas to be treated is sulphur oxidised by being contacted with an oxidation catalyst consisting of at least one oxysulphide of a metal selected among Ni, Fe, Co, Cu, Cr, Mo and W, associated with a silicon carbide support, by operating at temperatures lower than the dew point of the sulphur formed and more particularly ranging between 30 DEG C and 70 DEG C: The invention is useful for eliminating H2S contained in gases of various origins with recuperation of said 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 oxysulfure d'un métal choisi parmi Ni, Fe, Co, Cu, Cr, Mo et W, associé à un support en carbure de silicium, en opérant à des températures inférieures au point de rosée du soufre formé et plus particulièrement comprises entre 30 °C et 70 °C. 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.
