A process for the catalytic selective oxidation of sulphur compounds in a hydrocarbonaceous feedstock to sulphur dioxide, wherein a gaseous feed mixture of the hydrocarbonaceous feedstock and a molecular-oxygen containing gas is contacted with a catalyst at a temperature of at most 500 ~C, the catalyst comprising a group VIII noble metal on a catalyst carrier, wherein the oxygen- to-carbon ratio of the feed mixture is below 0.15.

L'invention concerne un processus destiné à l'oxydation sélective catalytique de composés de soufre dans une charge hydrocarbonée en dioxyde de soufre. Ledit mélange d'alimentation gazeux de la charge hydrocarbonée et du gaz contenant de l'oxygène moléculaire est mis en contact avec un catalyseur à une température de 500·C tout au plus, le catalyseur renfermant un métal noble du groupe VIII sur un support catalytique, le rapport oxygène-carbone du mélange d'alimentation étant inférieur à 0,15.
