Abstract

D'une manière générale, la présente invention a trait à des catalyseurs à base d'oxyde de ruthénium et à des procédés pour la catalyse de l'oxydation et la conversion de dioxyde de soufre (SO2) en trioxyde de soufre (SO3) mettant en oeuvre de tels catalyseurs. Du SO2 à de faibles concentrations dans des flux de gaz de procédé peut être efficacement oxydé en SO3 à des températures relativement basses à l'aide de catalyseurs à base d'oxyde de ruthénium de la présente invention. Dans une utilisation, les catalyseurs à base d'oxyde de ruthénium sont utilisés dans l'étage de contact final pour la conversion de SO2 en SO3 dans des convertisseurs catalytiques à étages multiples utilisés dans la fabrication d'acide sulfurique.
