Abstract

A treatment method for reducing contaminating agents in liquid mixtures of substituted hydrocarbons used as fuels is provided. A supersaturated mixture of ferrous oxide is combined with the hydrocarbons and mixed to form a homogenous solution. The homogenous solution is allowed to separate by means of settling and an aqueous solution is decanted to thereby produce a refined liquid hydrocarbons.

DETAILED DESCRIPTION

[0023] There is a pressing need for a method that reduces pollutant agents in liquid substituted hydrocarbon mixtures used as fuels. The prior art teaches a number of refining steps to convert crude oil into industrially usable fuels. However, these fuels still have sulfur compounds, aromatic compounds, benzenes, xylenes, benzenes, toluenes, and others that do not burn properly when used. Accordingly, a better refining method is necessary to reduce the contaminating effects of fuels.

[0024] The process is achieved by supersaturating ferrous oxide in water. The ferrous oxide supersaturation process has been described by, for example, Martin, Scot T. Precipitation and dissolution of iron and manganese oxides. Environmental Catalysis, 2005, p. 61-81. This supersaturated solution serves as catalyzer for refining fuel.

[0025] The supersaturated ferrous oxide solution is mixed with the fuel. It is well known that the ferrous oxide supersaturated solution may be used in a proportion of up to 70% of said solution against 30% fuel. However, in the preferred embodiment, the mixture is done with 10% solution to 90% fuel (e.g., 100 liters of supersaturated ferrous oxide solution for each 1,000 liters of fuel to be refined).

[0026] The supersaturated solution must be mixed by constant fluid blending, either by agitation, fluid recirculation, or barometric variation. In the preferred embodiment, 1 liter of this mixture must be mixed for at least one minute.

[0027] The result of said mixing is a reduction of hydrocarbons in the final fuel. FIG. 1 shows a graphic result of gas chromatography of a commercially available diesel sample. The first spike belongs to the dichloromethane used as control solvent. FIG. 2 shows a graphic result of gas chromatography of a commercially available diesel after treatment with the claimed method. As can be seen in accordance with the retention time shown in FIG. 2, the amount of linear hydrocarbons has decreased, which demonstrates the refining capabilities of the method.

[0028] FIG. 3 shows the graphic result of gas chromatography of a commercially available gasoline sample. The first spike belongs to the dichloromethane used as control solvent. FIG. 4 shows the graphic result of gas chromatography of the same commercially available gasoline sample after being treated with the claimed method. It will be appreciated that the quantity of cyclic hydrocarbons has also decreased.

[0029] FIG. 5 corresponds to the analysis of commercially available jet fuel, and FIG. 6 corresponds to the analysis of the same jet fuel after being treated with the claimed method. The results are similar to those of diesel and gasoline.

INDUSTRIAL APPLICABILITY

[0030] This method is applicable to any industry in which fuel is used and there is a desire to reduce polluting combustion byproducts and improve fuel efficiency.
