Patent

CA 2430145

Description of a process for eliminating sulphur from a feed containing hydrogen sulphide, sulphur dioxide, carbon oxysulphide and/or carbon sulphide and a minimal quantity of benzene, toluene and/or xylenes in at least one reaction zone containing a catalyst, and recovering elemental sulphur and an effluent that is at least partially free of sulphur, the process being characterized in that the catalyst used is at least one catalyst containing a support comprising at least one compound selected from de group formed by alumina, titanium oxide and zirconia, the support further comprising at least one doping element selected from the group formed by iron, cobalt, nickel, copper and vanadium.

Précis de la divulgation On décrit un procédé d'élimination du soufre d'une charge contenant de l'hydrogène sulfuré, de l'anhydride sulfureux, de l'oxysulfure de carbone et/ou du sulfure de carbone et une quantité minime de benzène, de toluène et/ou de xylènes dans au moins une zone réactionnelle contenant un catalyseur, et on récupère du soufre élémentaire et un effluent au moins en partie débarrassé du soufre, le procédé étant caractérisé en ce qu'on utilise comme catalyseur au moins le catalyseur contenant un support comprenant au moins un composé choisi dans le groupe formé par l'alumine, l'oxyde de titane et la zircone, le support comprenant en outre au moins un élément dopant choisi dans le groupe formé par le fer, le cobalt, le nickel, le cuivre et le vanadium.
