Abstract

Cette invention concerne un catalyseur permettant d'obtenir du soufre selon le procédé de Claus. Ce catalyseur se compose de composés de calcium dans des proportions de 1,0 à 35,0 % en poids, ainsi que d'une solution solide à base d'oxyde de titane et d'un ou plusieurs oxydes de métaux choisis parmi du niobium, du tantale, ou un métal faisant partie des terres rares, laquelle solution représente jusqu'à 100,0 % du poids. Le procédé de préparation du catalyseur permettant de produire du soufre selon le procédé de Claus, consiste à traiter du tétrachlorure de titane à l'aide d'une solution aqueuse ou d'une suspension d'hydroxyde de calcium, puis à mettre en oeuvre ce processus dans des conditions permettant d'obtenir un catalyseur ayant la composition voulue.
