SELECTIVE CATALYSTS FOR NAPHTHA HYDRODESULFURIZATION

Naphtha is selectively hydrodesulfurized with retention of olefin content. More particularly, a CoMo metal hydrogenation component is loaded on a silica or modified silica support in the presence of an organic additive to produce a catalyst which is then used for hydrodesulfurizing naphtha while ret...

Beschreibung
Zusammenfassung:	Naphtha is selectively hydrodesulfurized with retention of olefin content. More particularly, a CoMo metal hydrogenation component is loaded on a silica or modified silica support in the presence of an organic additive to produce a catalyst which is then used for hydrodesulfurizing naphtha while retaining olefins. L'invention concerne l'hydrodésulfurisation de naphtha avec rétention de la teneur en oléfines. Plus particulièrement, un composant d'hydrogénation métallique CoMo est chargé sur une silice ou un support de silice modifié afin d'obtenir un catalyseur qui est ensuite utilisé pour assurer l'hydrodésulfurisation du naphtha tout en retenant les oléfines.
