Abstract
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.sup.-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.degree. C. to 300.degree. 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.
