BIOFUEL COMPOSITION, METHOD FOR PREPARING AN EMULSIFIED FUEL COMPOSITION, EMULSIFIED FUEL COMPOSITION, AND METHOD FOR PREPARING AN EMULSIFIED FUEL MIXER An emulsified biofuel composition comprising: (A) a continuous phase comprising about 50-95% by weight of at least one liquid vegetable or animal oil or mixtures thereof; (B) a water-containing dispersed phase comprising about 1-50% by weight of water; (C) about 1-25% by weight of hydroxyl-containing organic compound selected from the group consisting of mono-, di-tri-and polyhydric alcohols, provided that when a monohydric alcohol is used at least one of tert-butyl is also present. - alcohol, at least one C 2 -C 4 alkylene glycol or a mixture of both; (D) about 0.05-10% by weight of at least one emulsifier; wherein the dispersed water-containing droplets have an average particle size of less than about 20 micrometers. Biofuel is prepared from these components by mixing under high shear conditions, preferably with ultrasonic energy. The emulsifier (s) preferably exhibit a hydrophilic-lipophilic balance of about 8.5 to about 18 and the biofuel includes a cetane intensifier and a mixture of an alcohol and mono- or poly (alkylene glycol).
