摘要 |
The present invention relates to compositions to stabilize hydrocarbon fuel, over a range of alcohol and water concentrations, against phase separation, containing a blend of two or more wide or one or more wide and one or more tall gaint hydrophobe nonionic surfactants. It also relates to fuel compositions stable toward such phase separation, which include (a) a major portion of a hydrocarbon fuel; (b) a minor amount of a low-alkyl (C1-C3) alcohol; (c) a minor portion of water; and (d) a minor portion of a stabilizer comprising a blend of wide or wide and tall giant hydrphobe nonionic surfactants. Optionally, the fuel compositions also include (e) a minor amount of a combustion aid, such as a cetane improver and (f) a minor amount of a solvent, such as a water solubilizing higher (C4 to C16) alcohol. |
