CA 2388543

The invention is directed to a process for the catalytic reduction of sulphur dioxide from a gas mixture at least containing 10 vol. % of water, in which process the gas mixture is passed over a sulphur resistant hydrogenation catalyst in sulphidic form, at a space velocity of at least 2000 h-1, in the presence of a reducing component, preferably at least partly consisting of hydrogen, in a molar ratio or reducing component to sulphur dioxide of more than 10 up to 100, at a temperature of 125 °C to 300 °C, followed by passing the gas mixture, after the said reduction, through a dry oxidation bed for the oxidation of sulphur compounds, more in particular hydrogen sulphide, to elemental sulphur.

L'invention porte sur un procédé de réduction catalytique de SO2 contenant au moins 10 vol. % d'eau consistant: à faire passer le mélange gazeux sur un catalyseur d'hydrogénation résistant au soufre sous forme de sulfure à une vitesse spatiale d'au moins 2000 h<-1>, en présence d'un composant réducteur de préférence en partie de l'hydrogène, dans un rapport molaire composant réducteur/SO2 de plus de 10/100 et à une température de 125 DEG C à 300 DEG C; puis à faire passer le mélange gazeux après ladite réduction par un lit d'oxydation à sec pour oxyder les composés sulfurés, et plus particulièrement le sulfure d'hydrogène, pour obtenir du soufre élémentaire.
