Abstract:
A process for making an aqueous hydrocarbon fuel composition comprising:a) preparing at least one emulsifier to form a hydrocarbon fuel emulsifier mixture wherein the emulsifier comprises the reaction product of (A) a polyacidic polymer selected from the group consisting of C4 to C30 olefin/maleic anhydride copolymers, maleic anhydride/styrene copolymers, polymaleic anhydride, acrylic and methacrylic acid containing polymers, poly-alkyl acrylates, reaction products of maleic anhydride with polymers with multiple double bonds and combinations thereof, (B) at least one fuel soluble product made by reacting at least one hydrocarbyl-substituted carboxylic acid acylating agent, and (C) an ammonia or amine selected from the group consisting of a hydroxy amine, polymer amine or combinations thereof; b) mixing the emulsifier with a liquid hydrocarbon fuel to form a hydrocarbon fuel emulsifier mixture; and c) mixing the hydrocarbon fuel emulsifier mixture with water or water and ammonium nitrate under emulsification conditions to form an aqueous hydrocarbon fuel composition, wherein the aqueous hydrocarbon fuel composition includes a discontinuous phase, the discontinuous phase being comprised of aqueous droplets having a mean diameter of 1.0 micron or less.
