Diesel Fuel Lubricity

Biodiesel: Current Trends and Properties

“…The poor lubricity of low-sulfur petrodiesel fuels requires additization or blending with another fuel of sufficient lubricity to regain lubricity [66]. Biodiesel, which has inherently high lubricity, restores lubricity to such low-lubricity diesel fuels at blend levels of about 2% and higher [67, references therein].…”

Fuel Properties and Performance of Biodiesel

“…The reason is that the hydrodesulfurization process that eliminates the sulfur species from petrodiesel fuel also removes the polar oxygen -and nitrogen -containing species which had been responsible for this lubricity (Dimitrakis, 2003 ;Barbour et al , 2000 ;Wei and Spikes, 1986 ). The poor lubricity of low -sulfur petrodiesel (Dimitrakis, 2003 ;Wei and Spikes, 1986 ;Wall et al , 1999 ;Lacey and Westbrook, 1995 ;Tucker et al , 1994 ;Wang and Reynolds, 1994 ;Nikanjam and Henderson, 1993 ;Lestz, 1992a, 1992b ) requires additives or blending with another fuel of suffi cient lubricity.…”

“…Biodiesel inherently possesses good lubricity (Lang et al , 2001 ;Lacey and Westbrook, 1995 ;Drown et al , 2001 ;Van Gerpen et al , 1999 ;Galbraith and Hertz, 1997 ;Waynick, 1997 ). As Table 1.16 demonstrates, commercial biodiesel displays better lubricity than its neat major components, fatty acid esters, and its parent vegetable oil (see entries with triolein).…”

Dissolution of styrene–butadiene block copolymers in biodiesel

“…Biodiesel (which is a blend of methyl esters) is produced from domestic, renewable resources so that it can act as a clean‐burning alternative fuel 8. The lubricity of biodiesel, compared to regular diesel, can make polymer–biodiesel solutions more amenable for use as engine fuels 9, 10. The dissolution behavior of PS and low‐density polyethylene in biodiesel has been characterized by investigations of its dissolution kinetics and shear viscosity and by molecular dynamic simulations.…”
