Abstract:
1. A process for enhancing the lubricity characteristics of a fuel, the process comprising: (a) pressing a solid source plant or animal material containing oils, fats and greases to provide a first extract of oils, fats and greases having lower levels of lubricity enhancing compounds, and a pressed solid source material; (b) extracting said pressed solid source material to provide a second extract of an oil, fat and grease concentrate comprising triacyl glycerol molecules; (c) chemically modifying said triacyl glycerol molecules in the second extract of said oil, fat and grease so as to lower the average molecular weight thereof and produce modified triglyceride products; (d) fractionating said modified triglyceride products into first and second fractions wherein constituents of the first fraction are higher in molecular weight than a molecular weight of constituents of the second fraction and wherein the first higher molecular weight fraction includes lubricity enhancing compounds comprising dolichol, polyprenols, squalene and tocopherols; (e) collecting the first fraction of step (d) so as to provide a concentrate of said lubricity enhancing compounds; and (f) adding said concentrate to the fuel.
