Abstract

Describes a study of cold flow properties and oxidation stability of near zero sulfur diesel from Ural crude oil and fatty methyl esters (FAME) from different origins and their blends.  Authors was found that undercutting the petroleum diesel to obtain arctic diesel deteriorates its oxidation stability.  Anti-oxidant addition is required to keep the oxidation stability within acceptable limits.

The addition of commercially available FAMEs, produced from 100% rape seed oil; 70% soya and 30% palm oil; 50% rape seed oil and 50% sunflower oil, to the petroleum diesel depresses the cold filter plugging point (CFPP). The depressing effect on the conventional diesel CFPP of the FAME depends on the petroleum diesel and the FAME properties.
