CA 2135906

A gas to be processed containing H2S is subjected to a step in which the hydrogen sulphide is catalytically oxidised (1a) into sulphur at a temperature of 60-180 DEG C so that a sulphur deposit is formed on the catalyst and the sulfur-loaded catalyst (1b) is periodically regenerated at 60-180 DEG C then cooled to enable it to be reused in the catalytic oxidation step.

2135906 9421555 Le gaz à traiter renfermant H2S est soumis à une oxydation catalytique (1a) de l'H2S en soufre à des températures dans l'intervalle 60 ·C à 180 ·C avec dépôt du soufre formé sur le catalyseur et régénération périodique du catalyseur chargé de soufre (1b), puis refroidissement du catalyseur régénéré dans l'intervalle 60 ·C à 180 ·C pour une réutilisation dans la phase d'oxydation catalytique.
