Abstract:
The present invention relates to catalysts for hydrodesulfurizing naphtha streams. The catalysts are comprised of a suitable support material, and about 1 to about 10 wt. % MoO.sub.3, about 0.1 to about 5 wt. % CoO supported on a suitable support material. They are also characterized as having an average medium pore diameter from about 60 .ANG. to 200 .ANG., a Co/Mo atomic ratio of about 0.1 to about 1.0, a MoO.sub.3 surface concentration of about 0.5.times.10.sup.-4 to about 3.0.times.10.sup.-4 g MoO.sub.3 /m.sup.2, and an average particle size of less than about 2.0 mm in diameter.
