- 17 - PROCESS FOR HYDRODEMETALLATION OF HYDROCARBON OILS SUCH AS PETROLEUM RESIDUA ABSTRACT OF THE DISCLOSURE Hydrocarbon oils, particicularly petroleum residua, containing 50 - 2000 ppm by weight of metals and substantial amounts of sulfur are effectively cata- lytically hydrodemetallated by forming a three-phase slurry of said oil with hydrogen and a solid hydro- demetallation catalyst of 50 to 300 mesh particle size and passing the slurry through an elongated tubular reactor sized to provide a residence time of from 1.5 to 10 minutes and a liquid flow velocity of from 1 to 15 ft. per second at a temperature of 750° to 900°F and a pressure of 1500 to 2750 psig and, thereafter, isolating the treated oil from the catalyst.
