Naphtha hydrodesulfurization selectivity is increased by reducing the amount of CO<SB>X</SB> (CO plus CO2) in the hydrodesulfurization reaction zone to less than 100 vppm. While this is useful for non-selective hydrodesulfurization, it is particularly useful for selectively desulfurizing an olefin-containing naphtha without octane loss due to olefin saturation by hydrogenation. The CO<SB>X</SB> reduction is achieved by removing CO<SB>X</SB> from the treat gas before it is passed into the reaction zone.

Selon la présente invention, pour augmenter la sélectivité lors de l'hydrodésulfuration du naphte, on fait descendre la quantité de CO<SB>X</SB> (CO plus ? C0¿2?) présente dans la zone de réaction d'hydrodésulfuration à moins de 100 vppm. Si ce procédé convient particulièrement pour l'hydrodésulfuration non sélective, il convient encore mieux pour la désulfuration sélective d'un naphte contenant des oléfines sans perte d'octane en raison de la saturation des oléfines par hydrogénation. Pour obtenir la réduction en CO<SB>X</SB>, on retire du gaz de traitement le CO<SB>X</SB> avant son passage dans la zone de réaction.
