    Abstract: A process for the catalytic hydrofinishing of petroleum distillate in the lubricating oil boiling range (e.g., to produce lube oils, rubber oils, refrigerator oils, transformer oils, cable oils ATF and friction drive transmission fluids, etc.) comprises contacting a lubricating oil distillate stock with hydrogen, in the presence of a catalyst comprising a hydrogenating component selected from the group consisting of sulfides and oxides of (a) a combination of molybdenum and at least one iron group metal (e.g., Co, Ni, Fe, W) and (b) a combination of nickel and tungsten. Preferably, the hydrogenating component is composited with an inorganic oxide support (preferably refractory), and the contacting carried out at an average catalyst temperature of about 650-765* F. and with at least from 500 p.s.i. of hydrogen (preferably 800-3000 p.s.i.). The combination of conditions is so selected as to effect appreciable hydrogen consumption but no substantial cracking. Clay finishing of the catalytically hydrofinished product can be advantageous where it is desired to have such additional improvement as better electrical properties or lighter color.

    Abstract: A process of improving the quality stability of hydrocracked oils by hydrogenating such oils subsequent to the hydrocracking treatment. The hydrocracking conditions comprise a temperature of from 700* to 900* F. and preferably from 700* to 800* F. and a pressure of at least about -500 psi and preferably at least about 1,500 psi over a sulfided mixture of Group VI B metal and Group VIII metal as a catalyst. The hydrogenation conditions comprise a temperature of from about 600* and preferably 625* to 675* F. a pressure of at least about 3,000 psi and the same catalysts as used for the hydrocracking operation.

    Abstract: A PROCESS FOR HYDROCRACKING LUBRICATING OIL STOCKS TO LUBRICATING OILS OF HIGHER VISCOSITY INDEX IN WHICH THE PORTIONS OF A CRUDE SUITABLE FOR HYDROCRACKING ARE FRACTIONATED INTO A PLURALITY OF FRACTIONS COMMENSURATE WITH THE BOILING POINT, MOLECULAR WEIGHT, OR POLYFUSED-RING AROMATIC CONTENT AND EACH OF SAID FRACTIONS IS SUBJECTED TO HYDROCRACKING CONDITIONS COMMENSURATE WITH THE POLYFUSED-RING AROMATIC CONTENT OVER A HYDROCRACKING CATALYST AT A TEMPERATURE IN THE RANGE OF ABOUT 650* TO 875* F. AND A HYDROGEN PARTIAL PRESSURE OF AT LEAST ABOUT 1500 P.S.I. PREFERABLY, THE CHARGE STOCK S FRACTIONATED INTO THREE FRACTIONS, THE FIRST FRACTION BOILING IN THE RANGE OF ABOUT 650* TO 850*F., THE SECOND FRACTION BOILING IN THE RANGE OF ABOUT 850* TO 1000*F., AND THE THIRD FRACTION CONTAINING ALL THE MATERIAL BOILING ABOVE ABOUT 1000* F. WHICH HAS BEEN DEASPHATED; AND EACH OF THE FOREGOING FRACTIONS IS SEPARATELY HYDROCRACKED FOR AT LEAST A PORTION OF THE TOTAL TIME IT IS HYDROCRACKED, PREFERABLY OVER A HYDROCRACKING CATALYST COMPRISED OF A SULFIDE OF A GROUP VI METAL, LEFT-HAND COLUMN, AND/OR AN IRON GROUP METAL, AND

    MOST PREFERABLY A MIXTURE OF NICKEL SULFIDE AND TUNGSTEN SULFIDE IN A 1/1 TO 4.''1 METAL ION RATIO, AT A TEMPERATURE IN THE RANGE OF ABOUT 735* TO 825*F. AND A HYDROGEN PARTIAL PRESSURE OF ABOUT 2500 TO ABOUT 4000 P.S.I.

    Abstract: Hydrofinished petroleum products, useful as lube oils, rubber oils, refrigerator oils, transformer oils, cable oils, ATF and friction drive transmission fluids, etc., can be produced by a process comprising (1) solvent extracting petroleum distillate stock to obtain a raffinate product and an extract product, and (2) contacting at least one of these products with hydrogen, in the presence of a catalyst comprising a hydrogenating component selected from the group consisting of sulfides and oxides of a combination of nickel and molybdenum. The preferred petroleum distillate is naphthenic by viscosity-gravity constant classification.
