  TECHNICAL FIELD The present invention relates to an additive for hydrated biofuel, a hydrated biofuel using the same, and a method for producing the same.

In recent years, crude oil prices have risen and fossil fuels, which are global resources, are depleted, and CO _{2 and} other greenhouse gases and environmental pollutants that are emitted when they are used and lead to the destruction of the environment Therefore, research on a fuel in which an appropriate amount of water is mixed with fuel oil, so-called emulsion fuel, has been actively conducted.

  Emulsion fuel is generally a fuel in which water and surfactant are added to fuel oil (heavy oil, kerosene, light oil, waste oil, etc.) and mechanically stirred to disperse water in the fuel oil. It is known as a fuel that is effective to some extent for reducing the amount and environmental pollutants associated therewith. As such an emulsion fuel, for example, there are various ones including Patent Documents 1 to 5.

As described above, emulsion fuel has been researched and developed for many years, and is partly operated on a trial basis.
However, in the conventional emulsion fuel, fuel oil and water may be separated in a relatively short time after production, and a large amount of oil may move to the upper layer and a large amount of water may move to the lower layer, resulting in two layers. Various problems such as troubles in use due to such double layering, difficulty in storage (stockpile) and transportation and reduction of combustion efficiency and combustion calories due to the effect of water content, reduction of fuel efficiency and combustion chamber corrosion due to reduction of thermal efficiency, etc. It had various drawbacks and problems.

Therefore, in the emulsion fuel, these factors are overlapped, and although there are examples in which some of them are operated on a trial basis, the current situation is that they have not been sufficiently spread in the market.

The main properties of the additive for hydrobiofuel and the raw material or components of hydrobiofuel according to the present invention will be briefly described below.
All of the raw materials or components are used in various applications in the general market, and are easy to obtain because they have a large amount of distribution and are relatively inexpensive.

  There are many types of surfactants, but fatty acids are used in the present invention. There are various types of fatty acids having 4 to 30 carbon atoms. As a result of repeated trials and experiments by the present inventors, it has been found that fatty acids having 16 or more carbon atoms are particularly effective.

  Examples of fatty acids having 16 or more carbon atoms include palmitic acid, palmitoleic acid, margaric acid, stearic acid, oleic acid, paxenoic acid, linoleic acid, linolenic acid, eleostearic acid, tuberculostearic acid, arachidic acid, arachidonic acid, Examples include behenic acid, lignoceric acid, nervonic acid, serotic acid, montanic acid, melicic acid and the like. Among these fatty acids having 16 or more carbon atoms, it is preferable to use oleic acid, which is considered advantageous for acquisition and use, particularly from the viewpoint of the distribution amount, price, and the like. In the present invention, one type of surfactant selected from the group consisting of these fatty acids having 16 or more carbon atoms may be used, or a plurality of types of interfaces selected from the group consisting of these fatty acids having 16 or more carbon atoms. You may mix and use an active agent.

  Examples of the glycol alcohol include ethylene glycol, propylene glycol, diethylene glycol, polyethylene glycol and the like. Among these glycol-based alcohols, it is preferable to use propylene glycol, which is considered advantageous for acquisition and use, particularly from the viewpoint of distribution amount, price, and the like. In the present invention, one of the glycol alcohols exemplified here may be selected and used, or plural kinds of glycol alcohols exemplified here may be selected and mixed for use. Good.

  Examples of alcohols that can be synthesized from biomass include ethanol, methanol, propanol, and butanol. Among these alcohols that can be synthesized from biomass, it is preferable to use ethanol that is considered advantageous for acquisition and use, particularly from the viewpoint of the distribution amount, price, and the like. In the present invention, one kind of alcohol that can be synthesized from the biomass exemplified here may be selected and used, or plural kinds of alcohols that can be synthesized from the biomass exemplified here may be selected and mixed. May be used.

  Oleic acid is a light yellow or tan liquid, and is a fatty acid contained in animal and vegetable oils such as lard. Not soluble in water but soluble in organic solvents. Although it is the main component of the additive for hydrobiofuel according to the present invention, it is preferable to adopt one having a freezing point of 8 ° C. or lower in consideration of the freezing point of the completed additive.

Propylene glycol is a colorless, tasteless, odorless and hygroscopic liquid. Used as a moisturizer, lubricant, emulsifier, antifreeze, etc.
Ethanol (ethanol) has general alcohol properties, and can be mixed with various solvents such as polar solvents including water and various organic solvents including hydrocarbons. Used for sterilization and disinfection.

Ammonia (Ammonia) is a colorless gas at normal temperature and pressure, and has a unique strong irritating odor. Since it dissolves well in water, it is often used as an aqueous solution (aqueous ammonia).
Next, the action (role) of each component of the additive for hydrobiofuel will be described.

  The surface tension of fuel oil is relatively small (weak), while the surface tension of water is relatively large (strong). The surfactant acts to make it easier to become an emulsified state by reducing the surface tension of both the fuel oil and water and stirring and mixing them.

Propylene glycol serves to promote a reforming action that brings the surface tension of water closer to the surface tension of the fuel oil.
In contrast to propylene glycol, ethanol serves to promote a reforming action that brings the surface tension of fuel oil closer to the surface tension of water.

Ammonia (ammonia water) works to make water particles fine and combine fuel oil and water to solubilize water and include it in fuel oil.
In the production of the additive for hydrobiofuel, when the blending ratio of the surfactant exceeds 70 parts by weight, the progress of the action of reducing the surface tension of the fuel oil and water is slowed, and the function of other components tends to be suppressed. There is. Further, when the blending ratio of the surfactant is less than 55 parts by weight, the surface tension of the fuel oil and water tends not to be sufficiently reduced. Thereby, in any case, the hydrated biofuel using the hydrated biofuel additive is easily emulsified.

  When the proportion of propylene glycol exceeds 15 parts by weight, the reforming action of bringing the surface tension of water close to the surface tension of the fuel oil tends to slow down. Moreover, when the blending ratio of propylene glycol is less than 10 parts by weight, the modifying action tends to be insufficient. Thereby, in any case, the hydrated biofuel using the hydrated biofuel additive is easily emulsified.

  When the blending ratio of ethanol exceeds 25 parts by weight, the reforming action that brings the surface tension of the fuel oil close to the surface tension of water tends to be slowed. Moreover, if the blending ratio of ethanol is less than 15 parts by weight, the reforming action tends to be insufficient. Thereby, in any case, the hydrated biofuel using the hydrated biofuel additive is easily emulsified.

  Ammonia has the following properties. In the case of ammonia water (25% solution), when the amount exceeds 8.8 parts by weight, the action of making the water particles finer, combining the fuel oil and water, solubilizing the water and including it in the fuel oil slows down. Tend. In the case of ammonia, if the amount of solution per 100 g of a mixture of a surfactant, glycol alcohol, and alcohol synthesized from biomass exceeds 2.0 liters, the water particles are made finer and fuel oil and water The action of solubilizing water and solubilizing water and including it in fuel oil tends to slow down. Furthermore, in the case of aqueous ammonia (25% solution), if it is less than 5.5 parts by weight, the action of solubilizing the water and including it in the fuel oil tends to be insufficient. In the case of ammonia, the water is solubilized and included in the fuel oil if the dissolved amount per 100 g of a solution in which a surfactant, glycol alcohol, and alcohol that can be synthesized from biomass are mixed is less than 1.25 liters. There is a tendency for the action to be insufficient. This also makes it easier to emulsify the hydrated biofuel using the hydrated biofuel additive in any case.

In the production of the hydrous biofuel, if the blending ratio of the fuel oil is less than 58 parts by weight, there is a tendency that sufficient combustion efficiency and combustion calories cannot be obtained. In addition, when the blending ratio of the fuel oil exceeds 62 parts by weight, the emission of greenhouse gases such as CO ₂ and environmental pollutants that lead to environmental destruction of the earth tends to increase.

  The fuel oil used for the production of the hydrated biofuel can be selected from A heavy oil, gasoline, light oil, kerosene, kerosene (which may be used as jet fuel), vegetable oil, and biodiesel fuel. A heavy oil is a kind of heavy oil and is classified according to JIS standards by kinematic viscosity. Biodiesel fuel is also called BDF (registered trademark), and is a general term for diesel engine fuel made from biological oil. Biodiesel fuel is one of the biomass energies, and it can be used as a diesel engine by chemical treatment by removing glycerin from the oils and fats such as palm, jatropha, and waste cooking oil by transesterification. is there.

When the mixing ratio of water exceeds 27 parts by weight, there is a tendency that sufficient combustion efficiency and combustion calories cannot be obtained. Moreover, if the mixing ratio of water is less than 18 parts by weight, the emission of greenhouse gases such as CO ₂ and environmental pollutants that lead to environmental destruction of the earth tends to increase.

  If the blending ratio of the additive for hydro-biofuel is less than 15 parts by weight, water tends to be solubilized by making the water particles fine and combining the fuel oil and water so that they cannot be included in the fuel oil. is there. Moreover, if the blending ratio of the additive for hydrobiofuel exceeds 20 parts by weight, water can be solubilized and included in the fuel oil, but the blending ratio of the fuel oil is relatively reduced, so that sufficient combustion efficiency is achieved. And there is a tendency not to obtain calories burned.

  Production of the additive for hydrobiofuel is carried out by mixing and stirring 55 to 70 parts by weight of a surfactant, 10 to 15 parts by weight of a glycol-based alcohol, and 15 to 25 parts by weight of an alcohol that can be synthesized from biomass. Then, 5.5 to 8.8 parts by weight of aqueous ammonia (25% solution) is mixed and stirred for a required time to react. When ammonia (ammonia gas) is used instead of ammonia water, 1.25 to 2.0 liters are dissolved per 100 g of a solution in which a surfactant, glycol alcohol, and alcohol synthesized from biomass are mixed. In addition, about the reaction after mixing ammonia water or ammonia, a bubble-like thing generate | occur | produces in a solution and it can confirm by the temperature of a solution rising to about 40-55 degreeC.

In the water-added biofuel, the blending ratio of the fuel oil and the water-added biofuel additive and water is 58 to 62 parts by weight of the fuel oil, 15 to 20 parts by weight of the water-added biofuel additive, and 18 to 27 parts by weight of water. . In the production of the hydrobiofuel, 58 to 62 parts by weight of fuel oil and 15 to 20 parts by weight of the additive for hydrobiofuel are mixed and stirred for the required time, and 18 to 27 parts by weight of water is added to the resulting mixture. Stirring and mixing while adding, solubilizing and including water.
(Function)
First, after the fuel oil and water are mixed in the presence of the surfactant, the greatest factor that causes the fuel oil and water to separate or form two layers is that the surface tension of the fuel oil and water is greatly different.

  When the hydrobiofuel is produced using the hydrobiofuel additive according to the present invention, the size of the surface tension of the fuel oil and water becomes equal or very close to each other, so that It seems that water particles can be finely dispersed uniformly and solubilized and included. The reason for this is not clear, but even if the reason is not correct, it does not have any effect on the establishment of the present invention.

  The hydrobiofuel according to the present invention is considered to be solubilized in the fuel oil because the water particles become fine in the presence of the hydrobiofuel additive. It has the same transparency as the oil itself, and the fuel oil and water do not separate or stratify over time. Therefore, it is possible to maintain a transparent state without separation or double-layering even after several years from manufacture, that is, a state where water particles are solubilized in fuel oil.

In addition, when the biofuel is burned, it is burned in a state close to complete combustion as compared with a case where fuel oil itself that is generally used is used as fuel, so that combustion efficiency and combustion calories are improved, and CO ₂ etc. Generation of greenhouse gases and environmental pollutants can also be suppressed. This can be confirmed not only from the acquired data described later, but also from the color and amount of soot in the furnace as the test facility.

  Hereinafter, an embodiment of the present invention will be described. However, the present invention is not limited to this.

[Method for producing additive for hydro-biofuel]
In this example, oleic acid was used as a fatty acid having 16 or more carbon atoms, propylene glycol was used as a glycol alcohol, and ethanol was used as an alcohol that can be synthesized from biomass.

  First, the additive for hydrobiofuel was added to a stirring tank of a stirrer, 1.30 kg (65 parts by weight) of oleic acid as a surfactant, 0.24 kg (12 parts by weight) of propylene glycol, 0.34 kg of ethanol (17 parts). Parts by weight), and mix for 5 minutes. In addition, this stirring time can be suitably adjusted with the difference in the mixture ratio and quantity of each said component. This stirring time may be, for example, 5 to 10 minutes.

  After mixing oleic acid, propylene glycol and ethanol as described above, the mixture is stirred and mixed for 10 minutes while adding 0.12 kg (6 parts by weight) of aqueous ammonia (25% solution) to the stirring tank. This stirring time may be, for example, 5 to 10 minutes.

  Thereafter, a bubble-like substance is generated in the solution as the mixture, and the temperature of the solution gradually rises to about 40 to 55 ° C. due to generation of reaction heat. In addition, about temperature, it may deviate from the said temperature range by conditions, such as external temperature.

  The generation of the bubble substance in the solution and the increase in the temperature of the solution seem to mean the progress of the chemical reaction, but the mechanism is not clear. Then, if stirring is continued for a while, this bubble-like substance gradually disappears, and the temperature of the solution also returns to the original temperature. This seems to mean the end of the reaction. In this way, 2.0 kg of the additive for hydrobiofuel could be produced.

As the stirrer used in the production method, any known one can be used. As for the stirring method, there are various methods such as an agitator, a circulation pump, and a line mixer. In the production method according to the present invention, stirring was performed by a simple method of circulating by a commercially available circulation pump. Although there is no particular limitation on the strength of stirring, such as the discharge amount of the circulation pump, it is not necessary to perform vigorous stirring that generates bubbles.
[Method for producing hydro-biofuel]
Next, a method for producing a hydrated biofuel using the hydrated biofuel additive produced as described above will be described.

  Using a stirrer, 6.0 kg (60 parts by weight) of fuel oil A heavy oil and 2.0 kg (20 parts by weight) of the additive for hydrobiofuel produced as described above are mixed and stirred for 5 minutes. To do. The stirring time is not limited to this, and can be appropriately adjusted depending on the mixing ratio and amount of the raw materials. This stirring time may be, for example, 5 to 10 minutes.

  It is important to uniformly and uniformly mix the additive for hydrobiofuel into the fuel oil by sufficiently stirring by the stirring operation. By mixing evenly and uniformly, the water added thereafter can be uniformly dispersed in the fuel oil, solubilized and included.

  Next, the mixture is further stirred while adding 2.0 kg (20 parts by weight) of water to the stirred solution obtained by adding the additive for hydrobiofuel to the fuel oil. This stirring time is 10 minutes in this embodiment, but the stirring time is not limited to this, and can be appropriately adjusted depending on the blending ratio and amount of each raw material. This stirring time may be, for example, 5 to 10 minutes.

  Through these steps, it is considered that the water particles are finely dispersed and evenly dispersed in the fuel oil, solubilized and included, and the fuel oil A is the raw fuel oil without being emulsified. It was possible to produce 10.0 kg of hydrated biofuel having transparency equivalent to itself.

  In addition, it is important to add water after adding the additive for hydration biofuels to fuel oil as the order which mixes each component when manufacturing a hydration biofuel. When the additive for water-added biofuel and water are mixed directly, it will have a muddy viscosity, so the order of mixing should be correct.

  Moreover, although the stirrer used for manufacture of hydrated biofuel is a line mixer in a present Example, another stirrer can also be used. Moreover, the hydrated biofuel which uses the additive for hydrated biofuel which concerns on a present Example can be used without specifically limiting about the kind of water which is a raw material. That is, so-called hard water or soft water can be used, and ordinary tap water or well water can also be used.

The results of observing the appearance of the hydrobiofuel according to this example over time will be described below.
As a fuel to be compared, A heavy oil equivalent to that used as a fuel for fishing boats was used as a raw material for the hydrobiofuel of this example.

  Table 1 is the data which shows the external appearance of sample S1 and S2 from which elapsed time after manufacture of the A heavy oil and the hydrobiofuel which concerns on a present Example differs.

[Discussion]
As can be seen from Table 1, the sample S1 immediately after production has a transparency that is not so different from the A fuel oil itself, which is the raw fuel oil, and 878 days (about 2 years and 5 months) have passed since the production. Sample S2 was also darker than sample S1, but maintained a state of transparency. In addition, neither sample S1 nor sample S2 was separated into a fuel oil A fuel oil and water, nor was it layered. Thus, it was found that the hydrobiofuel according to this example can maintain a state in which separation and bilayering of fuel oil and water do not occur over a long period of time after production.
[Combustion test]
The result of the combustion test of the hydrous biofuel according to this example will be described below.

As a fuel to be compared, A heavy oil equivalent to that used as a fuel for fishing boats was used as a raw material for the hydrobiofuel of this example.
Moreover, the combustion test of A heavy oil and the hydrated biofuel which concerns on a present Example was done using the burner boiler. Data was measured at the Institute of Environmental Health Sciences using a measuring method in accordance with JIS standards such as the Orsat method, circular filter paper method, chemiluminescence method, and neutralization titration method.

Specifically, the exhaust gas composition such as CO ₂ is the Orzat method, the dust concentration is the circular filter paper method, the nitrogen oxide concentration is the chemiluminescence method, the sulfur oxide concentration is the neutralization titration method, the moisture content is the moisture absorption tube method, oxygen The concentration was measured by the zirconia method.

  The burner boiler used was a greenhouse SK-200KM-DF manufactured by Sanshu Co., Ltd., the circulation pump used was 15GPE 6.4 model manufactured by Ebara Seisakusho, and the line mixer was manufactured by OHR. The static mixer F type was used.

  Table 2 shows data comparing the combustion performance of Samples S1 and S2 having different elapsed times after the manufacture of the heavy fuel oil A and the hydrobiofuel according to this example.

[Discussion]
From Table 2, it was recognized that the combustion biofuel which concerns on a present Example raises a combustion temperature a little compared with A heavy oil. Also, hydrolytic biofuel was found to dust including CO _2, a greenhouse gas, nitrogen oxides emissions of various environmental pollutants such as sulfur oxides is greatly reduced. Moreover, the samples S1 and S2 showed almost the same value regardless of the elapsed time after the production of the hydrobiofuel.

Moreover, it can be summarized as follows from the result of the combustion test.
That is, the combustion of the hydro-biofuel in the burner boiler is the combustion of A heavy oil droplets that are fuel oil, and the A heavy oil vaporized by the physical phenomenon and the oxygen in the air form a mixture on the surface of the A heavy oil droplets. It seems that combustion proceeds. The water particles contained in the hydro-biofuel are heated by receiving radiant heat from this combustion, reach the boiling point, cause micro explosions one after another, and scatter secondary A heavy oil droplets by scattering the surrounding A heavy oil droplets. It is thought that atomization occurs.

  As described above, the fuel oil A, which is instantly fine (ultra-fine), increases the contact area with the air and rapidly complete combustion, soot and unburned carbon in the combustion exhaust gas. It seems to suppress the occurrence of. Further, the increase in the contact area can suppress an excessive amount of air necessary for combustion, and can suppress the removal of heat by the exhaust gas, so that the energy saving effect is increased.

  In order to satisfy this condition, it is most important to finely and uniformly disperse and include water particles in the fuel oil particles. However, since water particles usually have a relatively large surface tension, For example, it is difficult to reduce the fineness to 20 to 40 nanometers, and conventional emulsion fuels are in an emulsified state because the water particles are not sufficiently fine.

  Table 3 shows a comparison of the characteristics of the hydrated biofuel of this example and the conventional emulsion fuel. With regard to emulsion fuel, many companies in Japan are conducting experiments and research and can easily obtain them. Here, one of the emulsion fuels was used as a comparative example.

  It seems that the additive for hydrobiofuel according to the present example can make the particle size of water mixed with fuel oil finer to 20 to 40 nanometers. The fact that the particle size of water is in nanometer units can be proved by the fact that water is solubilized in A heavy oil and does not emulsify and the transparency is not so different from that of A heavy oil. Thus, the hydrobiofuel can be brought into a solubilized / included state in which finely divided water particles are dispersed uniformly in the particles of the A fuel oil, which is fuel oil, instead of simply mixing fuel oil and water.

In addition, since the size of the water particles contained in the emulsion fuel is in a micrometer unit and cannot be reduced to a nanometer unit, it is in an emulsified state.
Thus, the hydrobiofuel according to the present embodiment has a high combustion temperature / combustion efficiency and combustion calorie as compared with the emulsion fuel, and the fuel consumption does not decrease. Further, since the fuel oil and water are in a transparent inclusion state without being emulsified, they are not separated or double-layered. Therefore, it can be stored and transported for a long time, and the influence on the combustion engine such as corrosion of the apparatus can be reduced.
[Generator output test]
Then, the result of the generator output test of the water biofuel which concerns on a present Example is demonstrated below. In this test, a generator of type DCA90SPH (generator capacity 90KVA / 220V / 60Hz / 236A / power factor 0.8) located in the Fukuoka office of the construction machinery division of Nishitetsu Techno Service Co., Ltd. is used as the generator. Moreover, the apparatus of the type LE-125 of the same sales office was used as a load apparatus.

As a fuel to be compared, A heavy oil equivalent to that used as a fuel for fishing boats was used as a raw material for the hydrobiofuel of this example.
The results are shown in Table 4 below.

  As shown in Table 4, when the load factor was 100%, it was confirmed that the rotational speed of Example A was slightly lower than that of Comparative Example a. However, no difference was found between Example A and Comparative Example a in terms of current value by generating a rated current with an automatic voltage regulator provided in the generator.

  Furthermore, the generator output test similar to the above was conducted also about the hydrobiofuel manufactured using light oil instead of the heavy oil A in the hydrobiofuel used for said test. Here, the light oil which is the raw material of the said hydrobiofuel was used as a fuel used as a comparison object.

  The results are shown in Table 5 below.

  As shown in Table 5, when the load factor was 100%, the rotational speed of Example B was confirmed to be slightly lower than that of Comparative Example b. However, as for the current value, no difference was observed between Example B and Comparative Example b by generating a rated current with an automatic voltage regulator provided in the generator.

From the above, in the generator output test, it was confirmed that the present invention can obtain an equivalent output between the hydrated biofuel (Examples A and B) and the JIS fuel (Comparative Examples a and b).
As mentioned above, although this invention was demonstrated, this invention is not limited only to the said embodiment. The above-described embodiment is an exemplification, and any device that has substantially the same configuration as the technical idea described in the claims of the present invention and has the same operational effects can be used. Included in the technical scope.
