Title (EN) NAPHTHA DESULFURIZATION WITH SELECTIVELY SUPPRESSED HYDROGENATION
(FR) DESULFURATION DU NAPHTA A HYDROGENATION SUPPRIMEE DE MANIERE SELECTIVE
Abstract: front page image
(EN)Naphtha is selectively hydrodesulfurized in the presence of a sulfided, treated catalyst comprising at least a Group VIB metal catalytic component, to produce sulfur-reduced naphtha with reduced olefin loss due to saturation. The catalyst is treated with hydrogen, a selectively deactivating agent which deactivates its hydrogenation activity, and a protective agent which preserves its hydrodesulfurization activity during the treatment.
(FR)Selon l'invention, le naphta est hydrosulfuré de manière sélective, en présence d'un catalyseur sulfuré, traité, comprenant au moins un composant catalytique métallique du groupe VIB, ceci permettant de produire du naphta à teneur en soufre réduite avec une perte d'oléfine provoquée par la saturation. Ledit catalyseur est traité avec de l'hydrogène, un agent de désactivation de manière sélective qui désactive son activité d'hydrogénation, et un agent de conservation qui protège son activité d'hydrodésulfuration pendant le traitement.
