Abstract: Methods are provided for upgrading disadvantaged feeds for use in lubricant base stock production. A disadvantaged feed can be upgraded by hydroprocessing the feed to form a hydroprocessed bottoms fraction. The hydroprocessed bottoms fraction can then be used as a feed for forming Group I and/or Group II lubricant base stocks, optionally in combination with a conventional feed for lubricant production. The remaining portions of the hydroprocessing effluent can optionally be used for FCC processing and/or for other conventional applications of naphtha and distillate fractions.

Abstract: Methods are provided for producing Group II/III lubricant base oil products where at least a portion of the feedstock for forming the lubricant base oil product is a solvent extract fraction from a Group I lubricant production facility. This can increase the overall volume of feedstock available for production of Group II/III lubricant base oils by using a lower value stream (Group I solvent extract) as a portion of the feedstock. The solvent extract fraction can be added to a full range lubricant feedstock or to a portion of a lubricant feedstock, such as adding an extract fraction to a higher viscosity portion (such as a heavy neutral portion) of a feedstock for lubricant production, while a lower viscosity portion (such as a light neutral portion) is processed without addition of an extract fraction.

Abstract: Methods are provided for producing lubricant base oils using a combination of catalytic and solvent processing. By using a combination of catalytic processing for feed conversion and dewaxing while using solvent processing for removal of aromatics, Group II and Group III lubricant base oils can be produced using low pressure catalytic processes.

Abstract: Disclosed are lubricating compositions comprised of a mineral oil base stock including one or more components selected from the group consisting a Group I base oil component, a Group II base oil component, and a Group III base oil component; and a minimal amount of a particular polyalphaolefin component. The lubricating compositions provide improved film thickness and wear properties relative to conventional mineral oil lubricants. In particular, the lubricating compositions provide improved film thickness and wear properties relative to conventional mineral oil lubricants, without the need of having to include additional polar additives to enhance wear and film thickness characteristics.

Abstract: Provided are lubricant compositions with improved oxidative stability and frictional and wear resistance properties for use in engine oil applications. The lubricant compositions include: i) a first base stock selected from a Group I base stock, a Group II base stock or a combination thereof at 50 to 80 wt %; ii) a block copolymer at 1 to 10 wt %; iii) a viscosity modifier at 3 to 15 wt % selected from polymers and copolymers of methacrylate, butadiene, olefins and alkylated styrenes; and iv) an additive package including a combination of antioxidants, dispersants, detergents, friction modifiers and antiwear agents at 2 to 30 wt %.

Abstract: Provided are lubricating compositions comprising in admixture at least 40 wt % of a base stock selected from the group consisting of Group I, Group II, Group III, Group IV and Group V base stocks, or any combination thereof, and one or more polyetheramines. Also provided are methods of improving the friction and wear properties of a base stock selected from the group consisting of Group I, Group II, Group III, Group IV and Group V base stocks, or any combination thereof, comprising blending the base stock with one or more polyetheramines, to form a lubricating composition.

Abstract: The resistance to deposit formation in formulated lubricating oils is enhanced by the addition to the lubricating oil of an additive amount of ionic liquids.
