Fuel additive

Abstract

A fuel additive contains ferrocene and/or ferrocene derivative(s), and lecithin. A fuel additive contains 80 to 99 mass % of ferrocene and/or ferrocene derivative(s), and 1 to 20 mass % of lecithin, and being in the solid state. A fuel additive contains 78 to 99 mass % of ferrocene and/or ferrocene derivative(s), 0.9 to 20 mass % of lecithin and 0.1 to 2 mass % of water, and being in the particle state. A fuel additive containing 2 to 5 mass % of ferrocene and/or ferrocene derivative(s), 5 to 50 mass % of lecithin and mineral oil, and being in the liquid state, wherein the ferrocene and/or ferrocene derivative(s), and the lecithin are dissolved in the mineral oil. The above-mentioned fuel additive is used by being added into a fuel so as to make the concentration of the ferrocene and/or ferrocene derivative(s) and the lecithin in ranges of 1 to 50 ppm, and 0.01 to 500 ppm, respectively.

Description

TECHNICAL FIELD[0001]The present invention relates to a fuel additive containing ferrocene and / or ferrocene derivative(s), and, more particularly, relates to a fuel additive containing ferrocene and / or ferrocene derivative(s) to which functions such as combustion promotion, soot reduction, NOx reduction and the like are enhanced by adding lecithin.DESCRIPTION OF THE RELATED ART[0002]Conventionally, ferrocene and derivative(s) thereof are used as an additive for various liquid fuels. For instance, ferrocene, derivative(s) thereof and a improvement combustion method of a liquid hydrocarbon in the presence of a fuel additive composition consisting of an aromatic solvent, an aliphatic solvent and / or a petroleum solvent which are liquid organic careers capable of dissolving the ferrocene and derivative(s) thereof are described in JP02-132188A. Moreover, a method of conditioning of diesel engines is described in U.S. Pat. No. 4,389,220 specification. In accordance with the method, a depos...

Benefits of technology

[0030]Lecithin in the present invention mainly provides the effect as follows.

[0031]Each above-mentioned effect is described below.

[0032]Ferrocenes have a drawback of low solubility in various fuels, as mentioned above. As used herein, the term “fuel” includes fuels used as a fuel for diesel engines, oil incinerators, boiler devices and the like, such as grade A heavy oil, light oil such as kerosene, gas oil and the like, heavy oil, heavy residue oil, lubricating oil, waste oil and mixed oil thereof, and also fuel emulsion thereof, and solid fuel such as coal and the like, but are not limited thereto, as long as the fuel is not in gaseous form.

[0033]For instance, in case of single ferrocene, a solubility in petroleum solvents such as aromatic solvent other than benzene, toluene and xylene, aliphatic solvent and the like is very low. Thus, in such a solvent as above mentioned, single ferrocene is soluble only up to 3% in concentra

Problems solved by technology

However, ferrocene and ferrocene derivative(s) used for these inventions have a drawback of very low solubility in an aromatic solvent, an aliphatic solvent and a petroleum solvent.

In order to dissolve solid ferrocene, in particular, a large quantity of agitation power and l
