Patent

CA 2677005

The present invention is generally directed to diester-based lubricant compositions. The present invention is also directed to methods of making these and other similar lubricant compositions. In some embodiments, the methods for making such diester-based lubricants utilize a biomass precursor and/or low value Fischer-Tropsch (FT) olefins and/or alcohols so as to produce high value diester-based lubricants. In some embodiments, such diester-based lubricants are derived from FT olefins and fatty acids. The fatty acids can be from a bio-based source (i.e., biomass, renewable source) or can be derived from FT alcohols via oxidation.

La présente invention concerne de manière générale des compositions de lubrifiant à base de diester. La présente invention concerne également des procédés de fabrication de ces compositions et d'autres compositions de lubrifiant semblables. Selon certains modes de réalisation, les procédés de fabrication de tels lubrifiants à base de diester utilisent un précurseur de biomasse et/ou des oléfines et/ou des alcools Fischer-Tropsch (FT) de faible valeur pour produire des lubrifiants à base de diester de valeur élevée. Selon certains modes de réalisation, de tels lubrifiants à base de diester sont dérivés d'oléfines FT et d'acides gras. Les acides gras peuvent être issus d'une source biologique (c.-à-d. biomasse, source renouvelable) ou peuvent être dérivés d'alcool FT par oxydation.
