Abstract:
1. A method of improving the combustion of a fuel composition in a combustion system with an exhaust, comprising providing a benefit selected from the group consisting of: stabilizing the fuel, or stabilizing a blended fuel comprising maintaining suitable properties for efficient delivery and combustion; reducing soot content and ash content of an exhaust of a combustion system; improving combustion efficiency of the combustion system; reducing maintenance down-times and increasing operational periods between down-times; improving fuel economy of the combustion system; allowing selection of a fuel previously thought unsuitable per se or previously thought unsuitable to blend with a fuel already in the fuel tank; and allowing selection of whatever fuel is available on the market at a given time; the method comprising providing a fuel and adding to the fuel an additive composition comprising: (i) a metal compound selected from the group consisting of an iron compound, a manganese compound, a calcium compound, a cerium compound, and mixtures thereof; (ii) an organic compound selected from the group consisting of a bicyclic monoterpene, substituted bicyclic monoterpene, adamantane, propylene carbonate and mixtures thereof; and (iii) a stabilizer selected from the group consisting of an asphaltene dispersant, a cold flow improver, a wax anti-settling additive and mixtures thereof; and combusting the fuel composition.
