Abstract
A low hydrogen partial pressure process for desulfurizing naphtha in the presence of a hydrodesulfurization catalyst which catalyst is selective for suppressing hydrogenation of olefins and in the presence. This invention also relates to the use of optimum metals loading for achieving a high level of hydrodesulfurization with a low level of olefin saturation.
