Abstract:
1. A combustible fuel composition of combustible liquid fuel and an additive as a clear microemulsion having water present, wherein said combustible liquid fuel is selected from the group consisting of kerosene, heating oil, coal slurry and distilled vegetable oil and said additive comprises: (a) ethanol having between 0.5 and 25% water by volume of ethanol; (b) one or more alcohols selected from the group consisting of: (c) a fatty acid of the structure R—(C═O)—OH, wherein R is alkyl or alkylene having between about 10 to 24 carbon atoms, in combination with ammonia or urea in an anhydrous state or as an aqueous solution; wherein components a, b, and c, as the additive when combined with mixing with combustible liquid fuel form a clear, stable microemulsion liquid fuel composition having a viscosity within 10% of the original viscosity of the combustible liquid fuel, and wherein the ratio of combustible liquid fuel to additive ranges from about 50:50 to 99:1 by volume, with the proviso that water is present in the composition sufficient to form the microemulsion and with the proviso that ethylene oxide condensation and ethylene oxide esterification products are completely eliminated.
