  • Lubricant compositions containing hexene-based oligomers
    Patent number: 10240102
    Abstract: Disclosed herein are oligomerization processes using feedstocks containing 1-hexene to produce an oligomer product, and methods for recovering a heavy 1-hexene oligomer from the oligomer product and hydrogenating the heavy 1-hexene oligomer. The resultant hydrogenated heavy 1-hexene oligomer can be blended with other PAO's to form 100 cSt and 40 cSt lubricant compositions, which have viscosity index and pour point properties that are equivalent to or better than respective 100 cSt and 40 cSt 1-decene PAO's.
    Type: Grant
    Filed: March 16, 2017
    Date of Patent: March 26, 2019
    Assignee: Chevron Phillips Chemical Company, LP
    Inventors: Brooke L. Small, Yemi Oyerinde, Russell J. Bak, Jeff C. Gee

  • Process for recovering boron trifluoride from a catalyst complex
    Patent number: 6410812
    Abstract: In a process for the oligomerization of alpha olefins using a boron trifluoride/alcohol catalyst complex a method for recovering the boron trifluoride from the product stream which comprises lowering the pressure of the product stream to flash off excess boron trifluoride, mixing the boron trifluoride with fresh alcohol to form fresh boron trifluoride/alcohol catalyst complex, and introducing the fresh catalyst back into the oligomerization reactor.

  • High viscosity polyalphaolefins
    Patent number: 5994605
    Abstract: A synthetic lubricant material is produced by forming a catalyst complex of a boron trifluoride catalyst and at least one alcohol promoter in the absence of olefinic monomer, then oligomerizing a C.sub.4-16 olefinic monomer by adding the olefinic monomer to a reaction vessel containing the catalyst complex, under boron trifluoride pressure, to produce an oligomer product. At least 50 weight % of the olefinic monomer is C.sub.8-16 olefinic monomer.
