Abstract: Hydrodesulfurization of an atmospheric residuum is effected by separating it into a vacuum gas oil and vacuum residuum and desulfurizing the gas oil fraction under less severe conditions than the heavy fraction. The vacuum residuum is contacted initially with a catalyst containing a Group VI metal and Group VIII metal or their sulfides on an alumina support containing 2-4 weight percent silica, a surface area of at least 250 m2/g. and a pore volume of at least 0.6 cc./g.; the effluent from the first zone is mixed with the gas oil fraction and the resulting mixture is then contacted with the catalyst at a lower temperature than the effluent temperature from said first zone.

Abstract: Petroleum oils of reduced sulfur content are produced by introducing into a catalytic hydrodesulfurization zone a residuecontaining petroleum oil of which at least 10 volume per cent boils below 1,000*F. separating the hydrodesulfurization zone effluent into a fraction boiling below about 1,000*F. and a fraction boiling above about 1,000*F. desulfurizing the fraction boiling below about 1,000*F. and combining the product with the fraction boiling above about 1,000*F. The catalyst in the first hydrodesulfurization should have a surface area of at least 250 m2/g., a pore volume of at least 0.6 cc/g and should contain at least 2 percent by weight silica.

Abstract translation: 降低硫含量的石油是通过向催化加氢脱硫区引入至少10体积沸腾至1000°F以下的含残油的石油，从而将加氢脱硫区流出物分成沸点低于约1000°F的馏分来生产的。 沸点高于约1000°F的馏分将沸点低于约1000°F的馏分脱硫，并将产物与沸点高于约1000°F的馏分结合。第一加氢脱硫中的催化剂的表面积应至少为250平方米 孔体积至少为0.6cc / g，并且应含有至少2重量％的二氧化硅。

Abstract: CATALYSTS USED IN RESIDUAL OIL HYDROPROCESSING HAVE THEIR ACTIVITIES RESTORED BY CONTACTING WITH A DISTILLATE OIL AT ABOUT 600 TO 800*F. AND 0 TO 3000 P.S.I.G. OPTIONALLY IN THE PRESENCE OF HYDROGEN; PURGING WITH HYDROGEN AND THEN WITH NITROGEN; STEAMING AT ABOUT 400 TO 800*F. AND BURNING WITH AN AIR STEAM MIXTURE AT A TEMPERATURE BELOW ABOUT 800*F.
