Effectiveness of Vegetable-Oil Fatty Acids as Antiwear Additives for Diesel Oils

The current study is devoted to the use of vegetable-oil fatty acids (FAs) as lubricity additives for modern diesel fuels with ultra-low sulfur contents. The effectiveness of liquid castor, linseed, coconut, and sunflower oils in the base components of diesel fuels for hydrotreating, hydrocracking,...

Zusammenfassung:	The current study is devoted to the use of vegetable-oil fatty acids (FAs) as lubricity additives for modern diesel fuels with ultra-low sulfur contents. The effectiveness of liquid castor, linseed, coconut, and sunflower oils in the base components of diesel fuels for hydrotreating, hydrocracking, and hydroisomerization is comparatively evaluated. It is established that all investigated vegetable-oil FAs are effective anti-wear additives as compared to a commercially available additive while FAs of castor oil, which consist of 90% ricinoleic acid, are most effective as anti-wear additives.
