Patent

CA 2637345

The invention relates to a catalyst for hydrodesulfurizing naphtha, to a method for preparing said catalyst and to a method for hydrodesulfurizing naphtha using said catalyst. More particularly, the catalyst comprises a Co/Mo metal hydrogenation component on a silica support having a defined pore size distribution and at least one organic additive. The catalyst has high dehydrosulphurisation activity and minimal olefin saturation when used to hydrodesulfurize FCC naphtha.

L'invention concerne un catalyseur pour l'hydrodésulfurisation de naphta, un procédé de préparation dudit catalyseur et un procédé d'hydrodésulfurisation faisant intervenir ledit catalyseur. De manière plus spécifique, le catalyseur comprend un composant d'hydrogénation métallique Co/Mo sur un support de silice présentant une distribution de taille des pores définie et au moins un additif organique. Le catalyseur de l'invention présente une activité d'hydrodésulfurisation élevée et permet de réduire la saturation des oléfines lorsqu'il est utilisé pour hydrodésulfuriser du naphta produit par FCC.
