Zusammenfassung: | A composition comprising at least one fuel that is a diesel fuel, a biodiesel fuel, or combinations thereof and less than 100ppm, less than 50ppm (or less than 25ppm, less than 10ppm, 1 to 7ppm, or 5 to 7ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500ppm (or 50 to 500ppm, or 150 to 450ppm or 250 to 450ppm, or 250 to 400ppm) of a terpolymer; and 5 to 90ppm, (or 10 to 70ppm, to 60ppm, or 10 to 55ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Methods of reducing the cold filter plugging point ("CFPP") of a fuel, said method comprising adding the following components: less than 100ppm, less than 50ppm (or less than 25ppm; less than 10ppm, 1 to 7ppm, or 5 to 7ppm) of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 25 to 500ppm (or 50 to 500ppm, or 150 to 450ppm or 250 to 450ppm, or 250 to 400ppm) of a terpolymer; and 5 to 90ppm, (or 10 to 70ppm, to 60ppm, or 10 to 55ppm) of hydrocarbyl-substituted amine detergent having at least one tertiary amino group. Uses of a fuel additive composition to reduce the cold filter plugging point ("CFPP") of a fuel, wherein the fuel additive composition comprises: 0.2 to 3wt% of an alkylene-coupled C10 to C60 (or C10 to C40, C14 to C32 or C24 to C28) alkylphenol; 10 to 50wt% of a terpolymer; and 2 to 10wt% of hydrocarbyl-substituted amine detergent having at least one tertiary amino group; and an optional solvent.
La présente invention concerne une composition comprenant au moins un carburant qui est un carburant diesel, un carburant biodiesel, ou des combinaisons de ceux-ci et moins de 100 ppm, moins de 50 ppm (ou moins de 25 ppm, moins de 10 ppm, 1 à 7 ppm, ou 5 à 7 ppm) d'un alkylphénol en C10 à C60 (ou C10 à C40, C14 à C32 ou C24 à C28) couplé à alkylène; 25 à 500 ppm (ou 50 à 500 ppm, ou 150 à 450 ppm ou 250 à 450 ppm, ou 250 à 400 ppm) d'un terpolymère; et 5 à 90 ppm, (ou 10 à 70 ppm, à 60 ppm, ou 10 à 55 ppm) d'un détergent à base d'amine substituée par hydrocarbyle comportant au moins un groupe amino tertiaire. L'invention concerne également des procédés d'abaissement de la température limite de filtrabilité (« CFPP ») d'un carburant, ledit procédé comprenant l'ajout des composants suivants : moins de 100 ppm, moins de 50 ppm (ou moins de 25 ppm; moins de 10 ppm, 1 à 7 ppm, ou 5 à 7 ppm) d'un alkylphénol en C10 à C60 (ou C10 à C40, C14 à C32 ou C24 à C28) couplé à alkylène; 25 à 500 pp |
