Definitions
- the catalyst composition used in the hydrocracking stage of the present invention can be prepared by adding the nickel, tungsten, molybdenum and boria components to the alumina by the various methods known to the art, for example by impregnation or precipitation and coprecipitation using suitable compounds of the metals and boron.
- alumina particles containing boria or a material which upon heating yields boria can be mixed with aqueous ammonia solutions containing nickel and tungsten, and/or molybdenum, or other aqueous solutions of water-soluble compounds of nickel and tungsten and/or molybdenum, so that the metal components are absorbed on the base.
- the solid catalyst employed in the hydrogenation operation is preferably a sulfur-resistant, nonprecious metal hydrogenation catalyst, such as those conventionally employed in the hydrogenation of heavy petroleum oils.
- suitable catalytic ingredients are tin, vanadium, members of Group VIB in the periodic table, i.e., chromium, molybdenum and tungsten and metals of the iron group, i.e., iron, cobalt and nickel. These metals are present in minor, catalytically effective amounts, for instances, about 2 to 30 weight percent of the catalyst, and may be present in the elemental form or in combined form such as the oxides or sulfides, the sulfide form being preferred.
- the hydrogenation operation provides additional aromatic saturation, color improvement and stability towards oxidation and corrosion. Additional color improvement can be provided by subjecting the effluent from the hydrogenation operation to treatment with ultraviolet light. The treatment was found to lighten considerably the color of the darker oils, a surprising result since such treatment usually produces the opposite effect.
- the reactor effluent from the hydrogenation stage may be flashed to recover hydrogen for possible recycle and fed to a steam stripper to remove excess light hydrogenated components.
- the oil can then be fractionated and the lube fractions dewaxed. This dewaxing step can be carried out, for example, by pressing or by solvent dewaxing using methyl ethyl ketone and toluene as the solvent system.
- Dewaxing may be carried out prior to the initial hydrocracking step but it is preferred to conduct dewaxing after hydrogenation has been completed. No additional finishing is required. Yields of about 60 to volume percent, based on the raw stock, of V1 oils are not uncommon and finished base oils having viscosity indexes of and higher are obtained in economical yields, e. g., in the range of about 40 volume percent and higher.
- Deasphalted petroleum residuum was fed to an isothermal reactor unit having a nickel-tungstate on boria-aluminia catalyst in the first or hydrocracking stage and nickel-molybdate on alumina catalyst in the second or hydrogenation stage.
- the catalysts were macrosize and presulfided.
- the feedstock employed had the following specifications:
- Viscosity SUS/210F. 154.4 Pour, F. 1 20+ ASTM color Dark Carbon residue (Con.), wt.% 1.58 10% boiling point 1,000F.
- Table I lists operating conditions and dewaxed oil inspections for nominal 100 and V1 operations.
- a process of preparing a mineral hydrocarbon lubricating oil having a viscosity index of at least about 90 on a dewaxed basis which comprises:
- step (b) Contacting hydrocarbon oil of lubricating viscosity from step (a) with molecular hydrogen under hydrogenation conditions including a temperature of about 550 to 825 F. in the presence of a solid hydrogenation catalyst at a hydrotreating severity such that not more than about 5 volume percent of the feed to step (b) boiling above 600 F. is cracked to material boiling below about 600 F. to produce oil of lubricating viscosity having a viscosity index of at least about 90 and at least about 20 viscosity index number greater than the hydrocarbon oil feedstock passing to step (a).
- hydrocracking conditions include a hydrogen partial pressure of about 1,000 to 5,000 p.s.i.g., a weight hourly space velocity of about 0.3 to 3 WHSV and a molecular hydrogen to hydrocarbon feed ratio of about 1 ,000 to 5,000 standard cubic feet per barrel of feed.
- hydrocracking catalyst contains about 2 to 10 weight percent nickel, about 10 to 20 percent of the member selected from the group consisting of tungsten and molybdenum on an oxide basis, and about 2 to 10 percent boria.
- a process of preparing a mineral hydrocarbon lubricating oil having a viscosity index of at least about on a dewaxed basis which comprises:
- a Contacting a mineral hydrocarbon oil feedstock of lubricating viscosity at 210 F., at least 90 weight percent of which boils above about l,000 F. and having a viscosity index of about 50 to 80, with molecular hydrogen under hydrocracking conditions including a temperature of about 750 to 850 F., a hydrogen partial pressureof about 1,500 to 3,000 p.s.i.g., a weight hourly space velocity of about 0.5 to 2 WHSV and a molecular hydrogen to hydrocarbon feed ratio of about 1,500 to 3,000 standard cubic feet per barrel of feed, in the presence of a catalyst containing about 2 to 10 weight percent nickel, about 10 to 20 percent tungsten on an oxide basis and about 2 to 10 percent boria on an active alumina support, the metals of the catalyst being present in the sulfide form; and Contacting hydrocarbon oil of lubricating viscosity from step (a) with molecular hydrogen under hydrogenation conditions, including a temperature of about 600 to 800 F.,
- step (b) is fractionated to separate oil of lubricating viscosity and the lubricating oil fraction is dewaxed.
- step (b) is fractionated to separate oil of lubricating viscosity and the lubricating oil fraction is dewaxed.
