No-Sulfur Fuel Lubricity Additive
US Patent:
8425628, Apr 23, 2013
Filed:
Aug 29, 2012
Appl. No.:
13/597367
Inventors:
Viet Q. Hoang - Houston TX, US
Philip L. Leung - Houston TX, US
Gordon T. Rivers - Houston TX, US
Philip L. Leung - Houston TX, US
Gordon T. Rivers - Houston TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
C10L 1/19, C07C 67/00
US Classification:
44389, 560204, 44385
Abstract:
Reacting an alkylene carbonate, such as ethylene carbonate, with dimer acid in the presence of a catalyst, such as a tertiary amine catalyst, gives a dimer acid diester having essentially no sulfur, and thus may be added to ultra-low sulfur diesel fuel downstream of a refinery. The diester enhances the lubricity properties of hydrocarbon fuels, increases their service life and fuel efficiency. The manufacturing process time may be decreased significantly compared with a process using ethylene glycol instead of ethylene carbonate, and much less ethylene glycol by-product results.
