  • Patent number: 10322980
    Abstract: Disclosed is a method of manufacturing high-quality lube base oil, by converting a low-value linear alpha-olefin having a C18 or more hydrocarbon chain into a linear internal-olefin having a controlled double bond position distribution and then oligomerizing the linear internal-olefin.
    Type: Grant
    Filed: April 22, 2015
    Date of Patent: June 18, 2019
    Assignees: SK Innovation Co., Ltd., SK Lubricants Co., Ltd.
    Inventors: Hee Jung Jeon, Jin Hee Ok, Tae Jin Kim, Wan Seop Kwon
  • Patent number: 9976098
    Abstract: Disclosed is a method for producing a quality lubricant base oil (meeting the standard of Group III or higher) comprising: decarbonylating mixed fatty acids derived from oils and fats of biological origin to produce mixed olefins; oligomerizing the mixed olefins to produce an olefinic lubricant base oil; and performing hydrogenation to remove olefins from the olefinic lubricant base oil.
    Type: Grant

  • Patent number: 9909047
    Abstract: Disclosed is a method of preparing a drilling fluid and lube base oil using biomass-derived fatty acid, including hydrogenating a fatty acid mixture derived from fat of biological origin so as to be converted into a fatty alcohol mixture, which is then dehydrated to give a C16 and C18 linear internal olefin mixture, which is then oligomerized to give olefinic lube base oil, followed by hydrofinishing to remove the olefin, yielding high-quality lube base oil (e.g. Group III or higher lube base oil). The C16 and C18 linear internal olefin mixture, which is a reaction intermediate, can be utilized as a high-quality drilling fluid.

  • Patent number: 9714209
    Abstract: A method for preparing an estolide compound and an estolide compound prepared thereby are disclosed. The method for preparing an estolide compound includes: converting biomass fat into a fatty acid; separating the fatty acid into a C16 saturated fatty acid and a C18 unsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the C18 unsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the C16 saturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.

  • Patent number: 9637701
    Abstract: A method for preparing a ketone group-containing estolide compound and a ketone group-containing estolide compound prepared thereby are disclosed. The method for preparing a ketone group-containing estolide compound includes converting biomass fat into a fatty acid; separating the fatty acid into a C16 saturated fatty acid and a C18 unsaturated fatty acid; increasing an amount of oleic acid through partial hydrogenation of the C18 unsaturated fatty acid; synthesizing a C35 ketone through ketonization of the oleic acid; and performing estolide bonding by capping the C16 saturated fatty acid onto the C35 ketone.
