The invention relates to an oil-in-water emulsion for use as a fuel and a process for preparing the oil-in-water emulsion. The oil-in-water emulsion comprises an oil phase dispersed in an aqueous phase; at least one primary surfactant selected from fatty alkyl amines, ethoxylated fatty alkylamines, ethoxylated fatty alkyl monoamines, methylated fatty alkyl monoamines, methylated fatty alkyl amines, and quaternary fatty alkyl amines, greater than 0.3 and up to 2.0 wt% of a secondary surfactant selected from one or more lignin amines; and an acid. The oil-in-water emulsion has: an average droplet size (D[4,3]) in the range of from 3 to 15 pm; less than 3wt% of the droplets have a particle size of greater than 125 pm; and a viscosity of greater than 100 and up to 700 mPas at 50 C 10% and 20 s -1 10%. L'invention concerne une émulsion aqueuse à utiliser comme un carburant et un procédé de préparation pour l'émulsion aqueuse. L'émulsion aqueuse comprend une phase huileuse dispersée dans une phase aqueuse; au moins un agent de surface sélectionné parmi des amines alkyles grasses, des alkylamines grasses éthoxylées, des monoamines alkyles grasses éthoxylées, des monoamines alkyles grasses méthylées et des amines alkyles grasses quaternaires; plus de 0,3 et jusqu'à 2,0 % massique d'un agent de surface secondaire sélectionné parmi une ou plusieurs amines de lignine; et un acide. L'émulsion aqueuse comprend : une dimension moyenne de gouttelette (0[4,3]) dans une fourchette de 3 à 15 µm; moins de 3 % massique des gouttelettes ont une dimension moyenne plus grande que 125 µm; et une viscosité plus grande que 100 et jusqu'à 700 mPas à 50 °C ± 10 % et 20 s - 1 ± 10 %.
