Title (EN) LUBRICITY ADDITIVES FOR LOW SULFUR HYDROCARBON FUELS
(FR) ADDITIFS PERMETTANT D'AMELIORER LE POUVOIR LUBRIFIANT D'HUILES HYDROCARBONEES COMBUSTIBLES A FAIBLE TENEUR EN SOUFRE
Abstract: front page image
(EN)The present invention relates to additives for enhancing the lubricity of hydrocarbon fuel oils, the inventive additive composition including one or more of the reaction products of (i) an alkylated polyamine and (ii) urea or isocyanate, or the salt adducts of these reaction products. More particularly, the present invention provides for a process for improving the lubricity of hydrocarbon fuel oils, which are low in inherent lubricity due to treatment to reduce sulfur and aromatic components for improved emissions.
(FR)L'invention concerne des additifs permettant d'améliorer le pouvoir lubrifiant d'huiles hydrocarbonées combustibles, comprenant un ou plusieurs produit(s) de réaction i) de polyamine alkylé et ii) d'urée ou d'isocyanate, ou les adduits de sel de ces produits de réacion. L'invention concerne plus particulièrement un procédé permettant d'améliorer le pouvoir lubrifiant d'huiles hydrocarbonées combustibles à faible pouvoir lubrifiant inhérent induit par un traitement permettant de réduire les composants soufrés et aromatiques à des fins d'amélioration d'émissions.
