Abstract

PURPOSE:To produce the title fuel which is stable, excellent in combustion efficiency and free from pollution, by microencapsulating a water-soluble liq. selected from among water, hydrogen peroxide and methanol in a petroleum fuel oil and dispersing the microcapsules in the fuel oil. CONSTITUTION:Emulsifying dispersion of at least one water-soluble liq. selected from among water, hydrogen peroxide and methanol as a dispersion phase is conducted in a petroleum fuel oil (e.g., light oil) as a dispersion medium in the presence of a film-forming material I soluble in the dispersion phase (e.g., polyethyleneimine or hexamethylenediamine), pref. using a dispersant (e.g., agar or carboxymethylcellulose). Then, a film-forming material II which is reactive with the film-forming material I and soluble in the dispersion phase (e.g., tolylene 2,4-diisocyanate) is added to thereby microencapsulate the water-soluble liq. Thus, a microcapsule-contg. fuel is obtd.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides water-soluble liquids such as water, hydrogen peroxide, and methanol in fuel oil, which are stable, have excellent combustion efficiency, and can contribute to prevention of pollution. The present invention relates to a mixed fuel containing a dispersed amount of and a method for producing the same.

[Prior Art] Mixed fuels such as emulsion fuel oil in which water is emulsified and dispersed in fine particles in fuel oil are known as fuel oils for saving fuel or preventing pollution. A known method for producing this emulsion fuel oil is to emulsify water using an aqueous solution of a surfactant or a water-soluble polymer; By simply adsorbing the emulsifier on the surface of the water particles, the stability of the dispersion is increased with the help of the viscosity of the fuel oil.
Low viscosity petroleum fuel oil (low viscosity heavy oil, tar oil, light oil, kerosene, diesel oil, jet fuel oil, gasoline, etc.)
It is difficult to emulsify water or alcohol into
It has not yet been possible to obtain a mixed fuel that can save fuel costs and prevent pollution.

[Problem to be solved by the invention]

The present invention solves the problems of conventional emulsion fuel oil, and allows microcapsules containing water-soluble liquids such as water, hydrogen peroxide, and methanol to be used in heavy oil, tar oil, light oil, kerosene, etc.
By making it in petroleum-based fuel oil such as diesel oil, jet fuel oil, and gasoline and dispersing it in petroleum-based fuel oil, it is possible to create a highly stable mixed fuel with high combustion efficiency and pollution prevention effect. The purpose is to provide a manufacturing method.

[Means to solve the problem]

The inventors of the present invention have conducted extensive research to solve the above-mentioned problems, and as a result, the above-mentioned objective has been achieved by microcapsulating a water-soluble liquid in petroleum-based fuel oil and dispersing it in petroleum-based fuel oil. The present invention was completed based on the discovery that this can be done.

That is, the present invention provides a mixed fuel consisting of a petroleum fuel oil and at least one water-soluble liquid selected from water, hydrogen peroxide, and methanol, wherein the water-soluble liquid is formed into microcapsules in the petroleum fuel oil. The present invention provides a microcapsule-containing fuel characterized by being dispersed in petroleum-based fuel oil.

The microcapsule-containing fuel of the present invention creates a film on the surface of the dispersed phase that is insoluble in the dispersed phase and the dispersion medium, encapsulates the dispersed phase, and prevents the agglomeration and coalescence of the dispersed phases, making it stable and combustible. It is possible to obtain a mixed fuel that is efficient and has a pollution prevention effect.

The petroleum fuel oil used in the present invention includes heavy oil, tar oil, light oil, kerosene, diesel oil, jet fuel oil, gasoline, etc., and is mixed with the water-soluble liquid and used as a mixed fuel. A polymer coating is usually used as the coating for the microcapsules.

The microcapsule-containing fuel of the present invention is produced by using, for example, petroleum fuel oil as a dispersion medium and at least one kind of water-soluble liquid selected from water, hydrogen peroxide, and methanol as a dispersed phase, and a film-forming raw material that is soluble in the dispersed phase. It can be produced by emulsifying the film-forming raw material II in the presence of I, then adding a film-forming raw material II soluble in a dispersion medium that is reactive with the film-forming raw material I, and microcapsulating the water-soluble liquid.

The ratio of petroleum fuel oil and water-soluble liquid is determined appropriately depending on the purpose of use, but for example, when used as a fuel for boilers, etc., the ratio of the former to the latter is preferably 80 = 20 to 60:40. When used for diesel engines, the ratio is preferably 90:1O to 80:20. In addition, heavy oil, petroleum fuel oil for boilers,
It is preferable to use light oil or kerosene, water or an aqueous hydrogen peroxide solution as the water-soluble liquid, and for diesel engines, heavy oil, light oil, or diesel oil is used as the petroleum fuel oil, and methanol, water, Or it is preferable to use a mixture thereof. In order to form a microencapsulated dispersed phase in a dispersion medium, a total volume of preferably 10 to 50% by volume containing a film-forming raw material such as a soluble monomer or polymer in the dispersed phase is added as necessary. The particles are emulsified and dispersed in a dispersion medium as uniformly as possible to a particle size of about 1 to 30 microns, and a film-forming raw material II that is reactive with film-forming raw material (1) such as a monomer or polymer soluble in the dispersion medium is added thereto. Then, microcapsules made of dispersed phase particles whose surfaces are covered with a coating of polymer or the like in a dispersion medium are obtained.

Emulsification and dispersion is carried out by stirring and mixing the dispersion medium and the dispersed phase using, for example, a stirring device. As the stirring device, various types of stirring devices can be used, such as a blade type, paddle type, propeller type, helical shaft type, and helical ribbon type. Further, an emulsifying machine such as a homomixer or a homogenizer can be used.

In order to aid emulsification and dispersion, if necessary, add a dispersant, emulsifier, protective colloid, etc. to the dispersed phase or dispersion medium in advance.
Emulsification can be carried out by adding a dispersant (hereinafter simply referred to as a dispersant).

Further, in order to promote the reaction between the film-forming raw material I and the film-forming raw material II, a catalyst can be added in advance to the dispersed phase or dispersion medium as necessary.

〔Example〕

Hereinafter, the present invention will be explained in detail based on Examples, but the present invention is not limited thereto.

Example 1 80 parts by weight of light oil, 0.02% by weight of a 30% aqueous solution of polyethyleneimine, and agar o as a dispersant.

20 parts by weight of an aqueous solution containing . Tolylene-2 was added to this system while continuing to stir.
, 4-diisocyanate to 1.5 of polyethyleneimine
Added double volume. As a result, a water-light oil mixed fuel containing microencapsulated water was obtained. This product remained stable even after being stored for more than 3 months, and there was no aggregation or coalescence of water. Tables 1 and 2 show the combustion results of light oil and its mixed fuel oil in a diesel engine. (Used engine: Isuzu Jidosha 60B1) Comparing Tables 1 and 2, the average value shows: (1) The amount of combustion (fuel consumption) increases by 11.4% compared to the 20% water capsule-containing twist material. However, the amount of diesel oil used was reduced by 8.6%.

(2) NOX generation is 20% and twisting agent containing water capsules is 0.

It was produced in heavy oil. Tolylene-2,4-diisocyanate was added to the system in a volume 1.5 times that of hexamethylene diamine while continuing to stir. As a result, a mixed fuel containing water and heavy oil was obtained by microcapsulating water. This product remained stable even after being stored for more than 3 months, and there was no aggregation or coalescence of water.

Tolylene-2, while continuing to stir this system,
Film-forming raw material II synthesized from 4-diisocyanate and fatty acid monoglyceride was added in an amount five times that of polyethyleneimine. As a result, a mixed fuel of methanol and light oil containing microencapsulated methanol was obtained.
