Abstract:
A process for making an aqueous hydrocarbon fuel composition, comprising:(A) mixing a normally liquid hydrocarbon fuel and at least one chemical additive to form a hydrocarbon fuel-additive mixture, wherein said chemical additive comprises an emulsifier composition which comprises: (i) a combination of (i)(a) a first hydrocarbon fuel-soluble product made by reacting a first carboxylic acid acylating agent with an alkanol amine, said first carboxylic acid acylating agent having a hydrocarbyl substituent containing about 50 to about 500 carbon atoms, and (i)(b) a second hydrocarbon fuel-soluble product made by reacting a second carboxylic acid acylating agent with at least one ethylene polyamine, said second carboxylic acid acylating agent having a hydrocarbyl substituent containing about 50 to about 500 carbon atoms; (ii) optionally an ionic or a nonionic compound having a hydrophilic lipophilic balance of about 1 to about 10; and (iii) an emulsion stabilizing and combustion improving amount of a water-soluble salt represented by the formula k[G(NR3)y]y+nXpâˆ’wherein G is hydrogen or an organic group of 1 to about 8 carbon atoms having a valence of y; each R independently is hydrogen or a hydrocarbyl group of 1 to about 10 carbon atoms; Xpâˆ’ is an anion having a valence of p; and k, y, n and p are independently integers of at least 1; and(B) mixing said hydrocarbon fuel-additive mixture with water under high shear mixing conditions in a high shear mixer to form said aqueous hydrocarbon fuel composition, said aqueous hydrocarbon fuel composition including a discontinuous aqueous phase, said discontinuous aqueous phase being comprised of aqueous droplets having a mean diameter of 1.0 micron or less.
