  • Hydroconversion process for making lubricating oil basestockes
    Patent number: 6974535
    Abstract: A process for producing a lubricating oil basestock having at least 90 wt. % saturates and a VI of at least 105 by selectively hydroconverting a raffinate from a solvent extraction zone in a two step hydroconversion zone followed by a hydrofinishing zone, and a lubricating oil basestock produced by said process.
    Type: Grant
    Filed: June 26, 2001
    Date of Patent: December 13, 2005
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Ian A. Cody, William J. Murphy, John E. Gallagher, Joseph P. Boyle, Anne M. Zinicola, Christopher J. May, Jeenok T. Kim, John A. Groestch, Sylvain S. Hantzer
  • Reffinate hydroconversion process
    Patent number: 6592748
    Abstract: A process for producing a high VI/low volatility lubricating oil basestock and a lubricating oil basestock prepared by said process. The process comprises subjecting the raffinate from a solvent extraction step to a two step, single stage hydroconversion process wherein the first step involves severe hydroconversion of the raffinate followed by a cold hydrofinishing step.
    Type: Grant

  • Selective extraction using mixed solvent system
    Patent number: 6416655
    Abstract: A method for concentrating the amount of alkylated mono-aromatics in a lubricating oil feedstock useful as a feedstock for sulfonation. The method comprises extracting a feedstock rich in aromatics with a solvent selected from NMP, phenol and furfural, said feedstock containing sufficient water to provide a raffinate having a target VI between about 86 and 97 under extraction conditions of treat and temperature selected to achieve the target VI. The raffinate is then hydrofmed and solvent dewaxed.
