TWO STAGE HYDRODESULFURIZATION PROCESS

摘要

A process for hydrodesulfurizing naphtha feedstreams wherein the reactor inl et temperature is below the dew point of the feedstock at the reactor inlet so that the naphtha will completely vaporize within the catalyst bed. It is preferred to use a catalyst comprised of about 1 to about 10 wt.% MoO3, abou t 0.1 to about 5wt.%CoO supported on a suitable support material. They are als o 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 MoO3 surface concentration of about 0.5 x 10-4 to about 3.0 x 10-4g MoO3/m2, and an avera ge particle size of less than about 2.0mm in diameter.
