Abstract
A water in diesel oil fuel micro-emulsion for internal combustion diesel engines, with a low content of surfactants, a very long shelf-life, a reduced production of pollutants and carbonaceous side-products generated by the combustion and very good engine performance, is described. These emulsions comply with the strict requirements of Italian regulations and are particularly useful as fuels for automotive and heating applications.
Claims18
Emulsifying composition for water in diesel oil fuel micro-emulsions comprising:
- from about 20.0% to about 33.0% by weight of at least a non ionic polymer, selected among polyglycerides of mono-, di- and tri-glycerides of fatty acids;
- from about 6.0% to about 10.0% by weight of at least a lipophilic non-ionic surfactant, having HLB lower than about 7 selected among sorbitan alkyl esters (Spans), fatty alcohols and their polyethoxylated derivatives, polyethoxylated fatty acid esters, glycerol esters and their admixtures;
- from about 16.0% to about 29.0% by weight of at least a hydrophilic non-ionic surfactant having HLB higher than about 10 selected among polyoxyethlyene derivatives of sorbitan alkyl esters (Tweens), ethoxylated fatty alcohol, polyethoxylated fatty acid esters, glycerol esters and their admixtures;
- from about 6.5% to about 11.5% by weight of at least an anionic surfactant selected among organic sulfates, sulfonates, phosphates and carboxylates salts;
- and
- from about 9.5% to about 16.5% by weight of at least an amphoteric surfactant.
