SELECTIVE HYDRODESULFURIZATION CATALYST AND PROCESS

摘要

A catalyst and process for hydrodesulfurizing naphtha feedstreams wherein the reactor inlet temperature is below the dew point of the feedstock at the reactor inlet so that the naphtha will completely vaporize within the catalyst bed. The catalyst is comprised of about 1 to about 10 wt.% MoO3, 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 ANGSTROM to 200 ANGSTROM , a Co/Mo atomic ratio of about 0.1 to about 1.0, a MoO3 surface concentration of about 0.5 x 10<-4> to about 3.0 x 10<-4> g MoO3/m<2>, and an average particle size of less than about 2.0 mm in diameter.
