Abstract:
A process for hydrodesulfurizing naphtha feedstreams without excessive olefin saturation, which process comprises:feeding a naphtha feedstream to a hydrodesulfurization process unit containing a bed of hydrodesulfurization catalyst, which catalyst is comprised of:(a) an inorganic refractory support material; and(b) about 1 to 10 wt % MoO.sub.3 ; and(c) about 0.1 to 5 wt. % CoO; and(d) a Co/Mo atomic ratio of about 0.1 to 1.0; and(e) a median pore diameter of about 75 .ANG. to 175 .ANG.; and(f) a MoO.sub.3 surface concentration in g MoO.sub.3 /m.sup.2 of about 0.5.times.10.sup.-4 to 3.times.10.sup.-4 ; and(g) an average particle size diameter of less than about 2.0 mm, and(h) a metal sulfide edge plane area of from about 761 to 2800 .mu.mol oxygen/g MoO.sub.3 as measured by oxygen chemisorption.
