  • Patent number: 8927796
    Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.

The solid stick composition comprises a vinyl ester resin, for example, from about 20 to about 80 weight percent vinyl ester resin, a solid lubricant, for example from about 0 to about 80 weight percent lubricant, and optionally a friction modifier, for example from about 0 to about 40% weight percent friction modifier, or a combination of a solid lubricant and a friction modifier. The solid stick comprises at least one of the lubricant or the friction modifier. A method of controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces is also disclosed as well as a method of reducing lateral force in a rail system comprising applying the solid stick composition onto a wheel or rail surface.

  • Publication number: 20080182768
    Abstract: A diesel engine operating on a fuel containing from about 5 to about 100 wt. % bio-diesel components and being lubricated with a lubricating oil composition including a major amount of oil of lubricating viscosity, and a minor amount of at least one highly grafted, multi-functional olefin copolymer. The olefin copolymer is made by reacting an acylating agent with an olefin copolymer having a number average molecular weight greater than about 1,000 in the present of a free radical initiator to provide an acylated olefin copolymer having a degree of grafting (DOG) of the acylating agent on the olefin copolymer of at least 0.5 wt. %, and reacting the acylated olefin copolymer with an amine to provide the highly grafted, multi-functional olefin copolymer. As used, the highly grafted, multi-functional olefin copolymer is effective to reduce a viscosity increase in the lubricating oil composition for the engine.

  • Publication number: 20080182769
    Abstract: A penetrating lubricant with the capacity to offer a both penetration into rust and corrosion. Further, this lubricant actively penetrates the crystalline surface of the metal while exhibiting extreme pressure lubrication, non-migrating with lasting protection. Further lubricant exhibits dielectric strength of over 8000 volts, at the same time cleaning electrical contacts, thereby reducing resistance and associated heat. The preferred embodiment may contain alpha-olefins, low-odor aromatic solvents, base oils, and high flash mineral spirits.

  • Publication number: 20040254081
    Abstract: The present invention relates to an apparatus and method for delivering manganese from a lubricant source into a fuel combustion system or to the exhaust therefrom. By the present invention, manganese from the lubricant will interact with phosphorus, sulfur, and/or lead from the combustion products. In this manner, the manganese scavenges or inactivates harmful materials which have migrated into the fuel or combustion products, and which can otherwise poison catalytic converters, sensors and/or automotive on-board diagnostic devices. The present invention can also lead to improved durability of exhaust after treatment systems.
