Abstract:
A fuels additive metallic salt composition effective in improving the operation of diesel engine particulate traps when added to a diesel fuel so as to provide 1-25 ppm metal in the fuel which comprises an oil soluble or oil dispersible overbased metal salt of an acidic organic compound, said salt composition containing 5-85 wt.% of a stoichiometric excess of metal over that required to neutralize the anionic portion of the salt, the metal being selected from the group consisting of Ca, Fe, Mg, Sr, Na, Ti, Zr, Mn, Zn and Ce.
Abstract:
PROBLEM TO BE SOLVED: To provide a mixed metal catalyst additive which reduces the carbon particle emission in a hydrocarbon fuel burning system and improves the properties of slag and to provide a fuel composition containing it and a method for using it. SOLUTION: This additive for a hydrocarbon fuel is for a fuel composition and comprises a compound containing a transition metal, an alkali metal compound, and a compound containing magnesium. The method for using it in the hydrocarbon fuel burning system contains a step in which the additive is added to a fuel composition in a mount effective to improve the burning of the fuel composition and the properties of the slag.

Abstract:
PROBLEM TO BE SOLVED: To provide an additive composition which is stable and effective for improving the quality of a gas released by the combustion of a diesel fuel. SOLUTION: The fuel additive iron salt composition is effective for improving the action of a diesel engine particulate substance trap when it is added to a diesel fuel so as to give an iron content of 1-25 ppm to the fuel. The composition contains an oil-soluble or oli-dispersible neutral or perbasic iron salt of an acidic organic compound. In the composition, 50-99 mol% of all the iron is in a ferric state, the balance being in a ferrous state. COPYRIGHT: (C)2004,JPO
