The features and remarkable actions / effects of the present disclosure other than those described above will be clarified to those skilled in the art by referring to the sections and drawings of the embodiments of the present invention below.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide an additive fuel (hydrated fuel) having high combustion efficiency and an additive to be added to a conditioned fuel oil for producing such an additive fuel (hydrated fuel). With the additive of the present invention, it is possible to produce an additive fuel (hydrated fuel) in which uniform dispersion of oil and water is realized and combustion efficiency is improved, and uniform dispersion of the oil and water is stable for a long period of time. It is highly convenient because it can be transported and stored as a pre-adjusted fuel oil.

Hereinafter, the present disclosure will be described with reference to the best form. Throughout the specification, it should be understood that the singular representation also includes its plural concept, unless otherwise noted. Therefore, it should be understood that singular articles (eg, "a", "an", "the", etc. in English) also include the plural concept, unless otherwise noted. It should also be understood that the terms used herein are used in the sense commonly used in the art unless otherwise noted. Accordingly, unless otherwise defined, all terminology and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. In case of conflict, this specification (including definitions) takes precedence.

The definitions and / or basic technical contents of terms specifically used in the present specification will be described below as appropriate.

As used herein, "about" means ± 10% of the value that follows.

As used herein, the term "additive fuel" means that fine particles of water are dispersed in a continuous phase of a liquid fuel, and is obtained by adding water to the adjusted fuel oil. In the present specification, "additive fuel" can also be paraphrased as "hydrogenated fuel". The additive fuel (hydrogenated fuel) generally takes the form of a W / O emulsion. When the additive fuel (hydrogenated fuel) is sprayed into the air and ignited, the oil on the surface side of the W / O type emulsion burns, and the water on the inside suddenly boils and vaporizes due to the effect of combustion heat, and W The / O type emulsion expands in volume. As a result, the oil that surrounds the water is atomized and scattered around, increasing the contact area between the oil and air. As a result, the combustion of the oil content is promoted, and high combustion efficiency is achieved as the additive fuel (hydrogenated fuel) as a whole. In addition, since the oil content of the additive fuel (hydrated fuel) is reduced in the total additive fuel (hydrated fuel) by the amount of water contained, the same amount of heat as when the same volume of normal fuel is burned is obtained. If obtained, it is also effective in that limited oil resources can be saved.

As used herein, the term "adjusted fuel oil" is a fuel obtained by adding an additive to the fuel oil.

In the present specification, the "fuel oil" is a fuel that is a raw material for adjusted fuel oil and additive fuel (hydrogenated fuel), and is, for example, gasoline, kerosene, light oil, A heavy oil, B heavy oil, C heavy oil, and crude oil. Includes general fuels such as vegetable oil, animal oil, waste oil, or paper waste black liquor.

As used herein, the "fatty acid" may be either a saturated fatty acid or an unsaturated fatty acid, for example, fatty acid, valeric acid, caproic acid, capric acid, capric acid, lauric acid, myristic acid, palmitic acid, and the like. Stealic acid, arachidic acid, behenic acid, lignoseric acid, α-linolenic acid, stearidonic acid, eikosapentaenoic acid, docosahexaenoic acid, linolenic acid, γ-linolenic acid, dihomo-γ-linolenic acid, arachidonic acid, oleic acid, erucic acid , Maleic acid, fumaric acid, dodecanoic acid, or esters thereof. Further, the higher fatty acid means, for example, one having 10 to 25 carbon atoms.

As used herein, "alcohol" includes, for example, methanol, ethanol, propanol, ethylene glycol, propylene glycol, and glycerin or a mixture thereof. Further, the alcohol having a relatively large molecular weight includes pentanol, hexanol, pentanol, undecanol, dodecanol, tridecanol and the like.

As used herein, the term "amine" refers to a compound in which a hydrogen atom of ammonia is replaced with a hydrocarbon group or an aromatic atomic group, and is any of a primary amine, a secondary amine, and a tertiary amine. May be good. For example, amines include methylamine, ethylamine, or propylamine.

(Preferable embodiment)
Hereinafter, preferred embodiments of the present disclosure will be described. The embodiments provided below are provided for a better understanding of the present disclosure, and the scope of the present disclosure should not be limited to the following description. Therefore, it is clear that a person skilled in the art can make appropriate modifications within the scope of the present disclosure in consideration of the description in the present specification. In addition, the following embodiments of the present disclosure may be used alone or in combination thereof.

In one aspect, the present invention is a method of making an additive used to produce an additive fuel or a conditioned fuel oil by adding it to a fuel oil by dissolving alcohol or a mixture thereof in a fatty acid. Provided is a method comprising a step of producing a product and a step of reacting the intermediate product with an amine to form an additive. In another aspect, the present invention provides an additive produced by the above method.

The present inventors have already obtained the finding that uniform dispersion of oil and water in the additive fuel (hydrogenated fuel) and its long-term stabilization are achieved by adding a specific additive to the fuel oil. The present inventors further proceeded with the study, and obtained the finding that the activity is higher than that of the conventional method and the synthesis time can be shortened, and the present invention was reached. The present invention provides a method which is a highly active additive, has improved operability, and has a shortened synthesis time as compared with the conventional method.

In one embodiment, the additive of the present invention can be obtained by adding an alcohol to a fatty acid, preferably a higher fatty acid, to form an intermediate product, and reacting the intermediate product with an amine. In one embodiment, the alcohol may be a mixture of two or more.

In one embodiment, alcohols having a relatively large molecular weight can be used instead of fatty acids. Alcohols having a relatively large molecular weight are alcohols having a molecular weight of at least about 88 or more. Can be mentioned. In other embodiments, it may be an alcohol having a side chain, such as an iso compound.

Further, as the alcohol added to the fatty acid or the alcohol having a relatively large molecular weight, an alcohol having a relatively small molecular weight can be used. The alcohol having a relatively small molecular weight is an alcohol having a molecular weight of less than about 182, and for example, methanol, ethanol, propanol, ethylene glycol, propylene glycol, glycerin or a mixture thereof can be used.

In one embodiment, the fatty acid can preferably be a higher fatty acid, such as fatty acid, valeric acid, caproic acid, capric acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behen. Acid, lignoseric acid, α-linolenic acid, stearidonic acid, eicosapentaenoic acid, docosahexaenoic acid, linoleic acid, γ-linolenic acid, dihomo-γ-linolenic acid, arachidonic acid, oleic acid, erucic acid, maleic acid, fumaric acid, A mono-polyvalent fatty acid such as dodecanoic acid, which can be dissolved in alcohol such as methanol, ethanol and propanol, can be used. In other embodiments, the fatty acid may be a mixture with a fatty acid ester as well as the fatty acid.

In one embodiment of the present invention, the additive of the present invention can be obtained by allowing an amine to act on an intermediate product obtained from a fatty acid and an alcohol, stirring well and adjusting the conditions to a certain condition.

In one embodiment, the amine added to the intermediate product is preferably a primary amine, and among them, methylamine, ethylamine, or propylamine can be preferably used. The reaction temperature at the time of producing the additive can be appropriately changed depending on the type of amine used, but can be carried out, for example, at room temperature, and the room temperature is referred to as about 20 ° C to about 40 ° C in the present specification. In another embodiment, the reaction temperature at the time of forming the additive is, for example, about 20 ° C. or higher, about 23 ° C. or higher, about 25 ° C. or higher, about 27 ° C. or higher, about 30 ° C. or higher, about 35 ° C. or higher, about 40 ° C. As described above, the heating temperature may be about 45 ° C. or higher, about 50 ° C. or higher, preferably about 25 to about 60 ° C., and more preferably about 40 to about 55 ° C. Further, the stirring condition is preferably stirring in a range where air is less mixed. At the time of production, heat is generated, so it is preferable to sufficiently stir so that the reaction becomes uniform.

Since there are various combinations of raw materials, the optimum ratio varies depending on the raw material, but a rough ratio is, for example, fatty acid or relatively high molecular weight alcohol: relatively small molecular weight alcohol or a mixture thereof: amine = about. 1: About 1.0 to about 2.5: About 0.001 to about 0.7 (mol concentration), more preferably fatty acids or relatively high molecular weight alcohols: relatively small molecular weight alcohols or mixtures thereof: amines. = About 1: About 1.1 to about 2.2: About 0.003 to about 0.2 (mol concentration).

By appropriately adjusting the types of fatty acids and the like that are the raw materials of the additives according to the types of fuel oil to be added, the amount of water added when obtaining the additive fuel (hydrogenated fuel) can also be optimized.

In the conventional method, alcohol is added to fatty acid to produce an intermediate product, and ammonia gas or aqueous ammonia is allowed to act on the intermediate product to synthesize an additive. In the method using ammonia gas (NH ₃ ), if the amount of ammonia added exceeds an appropriate amount, the additive activity will drop at once, so it is necessary to pay close attention to the control of the amount of ammonia gas added. rice field. Also, when using ammonia water (NH ₄ OH), it is difficult to control the amount of ammonia dissolved in the ammonia water itself, so it cannot be said that the operability is high. In one embodiment of the present invention, when an additive is synthesized using methylamine, the amount of amine to be added (MeNH ₂ amount (MeOH ₂ / MeOH)) can be controlled in mmol units. Therefore, when an amine is used, the operability can be significantly improved as compared with the conventional method using ammonia gas (NH ₃ ) or ammonia water (NH ₄ OH).

Further, in the case of synthesizing an additive using conventional ammonia gas, if an excess amount of ammonia gas is added, the additive gels, and it is difficult to adjust the amount. When ammonia water is used, it gels because the water already exists. In this respect, in the method of the present invention, by using amine instead of ammonia gas or aqueous ammonia, the amount can be easily adjusted and the operability can be improved.

Further, in the case of conventional additive synthesis produced using ammonia gas (NH ₃ ) or ammonia water (NH ₄ OH), it takes 4 to 6 hours per batch for the synthesis. In one embodiment of the present invention, when an additive is synthesized using methylamine, it can be synthesized in about 1 to 2 hours per batch, and the synthesis time is shortened to 1/2 to 1/3. be able to.

In one embodiment of the present invention, the additive of the present invention is about 1.5 to about twice as high as the additive obtained by using conventional ammonia gas or aqueous ammonia with a predetermined activity standard. Activity can be obtained. As the activity standard, for example, it can be calculated by the amount of water added (g) / additive (g) to a certain amount of fuel (kerosene, light oil, etc.) at a certain temperature. For example, an additive (0.5 g) is added to 1.0 g of light oil, H ₂ O is added dropwise to this mixture, and the activity standard is calculated from the amount of H ₂ O that can be completely uniform without becoming cloudy. Can be done. For example, if the amount of H ₂ O dropped is 0.5 g with respect to the additive (0.5 g), the activity of the additive can be calculated as 1.0, or the activity of the additive can be calculated to be 1.0 with respect to the same amount of the additive. If the amount of H ₂ O obtained is 1.0 g, the activity of the additive can be calculated as 2.0, and this value can be compared as the activity reference of the additive.

As described above, the present invention is compared with the case where conventional ammonia water or ammonia gas is used by adding an alcohol to a fatty acid, preferably a higher fatty acid, to form an intermediate product and adding an amine to the intermediate product. Therefore, in the additive fuel (hydrated fuel) obtained by adding the additive to the fuel oil, the oil and water can be made transparent in a uniform mixed state without separation. Further, an additive having higher activity can be obtained as compared with the additive obtained by the conventional method. Such excellent stability and activity as compared with the prior art are brought about by improving the efficiency (higher yield) of the production rate of the fatty acid derivative having a surface-active ability. In addition, since the amine itself used as a substitute for conventional ammonia water or ammonia gas has a carbon chain moiety and an amino group moiety, it is said that it effectively works to improve the surface activity of the additive as a whole. Conceivable. Therefore, it is impossible or impractical to directly specify the additive of the present invention by its structure or properties as a product.

In one aspect, the present invention is a method for producing a regulated fuel oil that can be used as an additive fuel by adding water, and comprises a step of adding an additive as described above to the fuel oil to produce a regulated fuel oil. , Provide a method. In yet another aspect, the invention provides a conditioned fuel oil produced by such a method.

In one embodiment, the required amount of the additive for producing the adjusted fuel oil varies depending on the type of fuel oil, the type of alcohol added to the fatty acid, and the type and amount of amine added, but as a rough ratio, For example, additive: fuel oil = about 0.001 to about 0.5: about 1 (volume), preferably about 0.015 to about 0.5: about 1 (volume), more preferably additive: fuel. Oil = about 0.03 to about 0.3: about 1 (volume).

In one embodiment, as the fuel oil, general combustible oil such as gasoline, kerosene, light oil, A heavy oil, B heavy oil, C heavy oil, crude oil, vegetable oil, animal oil, waste oil, and paper mill waste oil (black liquor) can be used. ..

In one aspect, the present invention provides a method for producing an additive fuel, which comprises a step of adding water to the adjusted fuel oil as described above to produce an additive fuel. In another aspect, an additive fuel produced by such a method is provided.

In one embodiment, the required amount of water or adjusted fuel oil for producing the additive fuel (hydrated fuel) is the type of fuel oil used for producing the adjusted fuel oil (gasoline, light oil type, heavy oil type, etc.). ), Combustion facility (engine, boiler, etc.), the type of alcohol added to the fatty acid, and the type and amount of amine added, but as a rough ratio, the mixing ratio of water and adjusted fuel oil should be about 0.1 to It can be about 1: about 1 (volume), preferably about 0.2 to about 0.6: about 1 (volume). When used in a diesel engine, 1 L (volume 10%) of an additive can be added to 8 L (volume 80%) of light oil, and 1 L (volume 10%) to ₂ L of H2O can be added thereto.

If air is mixed in during stirring when manufacturing additive fuel (hydrated fuel), there is a risk of generating an explosive air-fuel mixture. Therefore, when manufacturing additive fuel (hydrated fuel), water and adjusted fuel oil are used. For mixing, stirring without mixing of air is preferable. Further, depending on the ratio of water to be mixed, the produced fuel may be liquefied or gelled, and if the ratio of water is too high, the combustion temperature and the combustion calories are lowered. For example, when the fuel is used for a gas turbine, it is preferable to use water for the boiler as water supply. If the mixing ratio of the raw materials of the additive is not sufficiently appropriate, or if the reaction of the additive is not sufficiently promoted, a white precipitate may be formed after water addition depending on the reaction temperature, but it interferes with combustion. There is no.

In the present invention, as described above, the additive of the present invention is added to the fuel oil to produce an adjusted fuel oil, and water is added to the adjusted fuel oil thus obtained to produce an additive fuel (hydrated fuel). can do. The additive of the present invention cannot be distinguished from the additive obtained by other methods depending on its composition. Therefore, it is impossible or impractical to directly specify the adjusted fuel oil and the additive fuel (hydrogenated fuel) of the present invention by the structure or characteristics as a substance.

As used herein, "or" is used when "at least one" of the matters listed in the text can be adopted. The same applies to "or". When "within a range" of "two values" is specified in the present specification, the range also includes the two values themselves.
References such as scientific literature, patents, and patent applications cited herein are hereby incorporated by reference in their entirety to the same extent as they are specifically described.

The present disclosure has been described above with reference to preferred embodiments for ease of understanding. Hereinafter, the present disclosure will be described based on examples, but the above description and the following examples are provided for purposes of illustration only and not for the purpose of limiting the present disclosure. Therefore, the scope of the present disclosure is not limited to the embodiments and examples specifically described in the present specification, and is limited only by the scope of claims.

(Example 1: Production of amine-based additive)
In this example, an additive to be added to an additive fuel (hydrogenated fuel) or adjusted fuel oil was produced. Amine-based additives were synthesized using oleic acid, methanol, ethylene glycol (or glycerin), and methylamine.

First, 100 g of methanol was added to 500 g (1.77 mol) of oleic acid and stirred to make it uniform. To this, 90 g (0.98 ml) of glycerin (or 60 g of ethylene glycol) was added, and the mixture was further stirred to make it uniform. 130 ml (1.27 mol) of methylamine (40% (w / w) in MeOH) was added dropwise to this mixture with stirring to synthesize an amine-based additive.

In the case of conventional additive synthesis produced by using ammonia gas (NH ₃ ) or ammonia water (NH ₄ OH) instead of methylamine as in Comparative Examples 1 and 2 below, one batch is used for the synthesis. It took 4 to 6 hours per batch, but when the additive was synthesized using methylamine, it could be synthesized in about 1 to 2 hours per batch, and the synthesis time was 1/2 to 1/1. I was able to shorten it to 3.

In addition, in the conventional method using ammonia gas (NH ₃ ), if the amount of ammonia added exceeds an appropriate amount, the additive activity drops at once, so great care should be taken to control the amount of ammonia gas added. It was necessary. Also, when using ammonia water (NH ₄ OH), it is difficult to control the amount of ammonia dissolved in the ammonia water itself, so it cannot be said that the operability is high. In this regard, in this example, when an additive is synthesized using methylamine, the amount of amine to be added ( _MeNH2 amount (MeOH2 / MeOH)) can be controlled in mmol units. When an amine was used, the operability could be significantly improved as compared with the conventional method using ammonia gas (NH ₃ ) or ammonia water (NH ₄ OH).

(Comparative Example 1: Manufacture of Ammonia Gas Additive)
Ammonia gas-based additives were synthesized using oleic acid, methanol, ethylene glycol (or glycerin), and ammonia gas (NH ₃ ).

First, 600 g (2.12 mol) of oleic acid (MW = 282.46) was weighed in a 1 L beaker, 101 g (3.16 mol) of methanol was added, and the mixture was stirred to make it uniform. 73 g (1.18 mol) of ethylene glycol was added thereto, and the mixture was further stirred to make it uniform. Ammonia gas was added to this mixture at 120 ml / min with stirring. Ammonia gas-based additives were synthesized by bubbling at the flow rate of 1 to 2 hours.

(Comparative Example 2: Manufacture of Ammonia Aqueous Additive)
Ammonia aqueous additives were synthesized using oleic acid, methanol, ethylene glycol (or glycerin), and aqueous ammonia (NH ₄ OH).

1000 g (3.54 mol) of oleic acid (MW = 282.46) was weighed in a 2 L beaker, 170 g (5.31) of methanol was added, and the mixture was stirred to make it uniform. To this, 110 g (1.77 mol) of ethylene glycol was added, and the mixture was further stirred to make it uniform. While stirring the mixture, 150 g of 28% ammonia water was added to the dropping funnel at 1.0 g / min. To synthesize an aqueous ammonia-based additive.

(Example 2: Production of additive fuel)
The obtained additive is mixed with fuel oil such as gasoline, kerosene, light oil, A heavy oil, B heavy oil, C heavy oil, crude oil, vegetable oil, animal oil, waste oil, and paper mill waste oil (black liquid) and stirred. Adjustable fuel oil containing additives can be produced, and by adding water to this adjusted fuel oil, it can be used as an additive fuel (hydrated fuel).

A adjusted fuel oil containing an additive was produced by mixing and stirring 1 liter (volume 10%) of an additive with 8 liters (volume 80%) of light oil. An additive fuel (hydrogenated fuel) was produced by mixing and stirring 1 liter (volume 10%) of water with this mixed solution.

The additive fuel (hydrogenated fuel) obtained by using the amine-based additive of the present invention had high transparency without cloudiness, two-layer separation, or granular separation, and the oil and water remained in a uniform mixed state. Moreover, this uniform state was stably maintained for a long period of time.

(Example 3: Activity comparison)
In this example, for each of the amine-based additive, the ammonia gas-based additive, and the ammonia-based additive, the activity standard calculated by the amount of water added (g) / additive (g) to a certain amount of fuel at a certain temperature is used. The activity was compared. The activity standard is, for example, an additive (0.5 g) added to 1.0 g of light oil, H ₂ O is added dropwise to this mixture, and the activity is based on the amount of H ₂ O that can be completely uniform without becoming cloudy. The standard can be calculated. As a result, in the case of the conventional additive using ammonia gas (NH ₃ ) or ammonia water (NH ₄ OH), the activity was about 2.0, but in the case of the additive using methylamine. The activity was about 3.2, and it was possible to obtain a high activity of about 1.5 times.

(Example 4: Examination of various amines)
In this example, the results of synthesizing an additive using an amine other than methylamine and producing an additive fuel (hydrogenated fuel) using the additive were compared. As shown in the table below, no improvement in the activity of the additive was observed when dimethylamine was used. When ethylamine and propylamine were used, the same activity as the additive using methylamine could be obtained. Further, it was found that when the additive was synthesized under the heating condition of 40 to 55 ° C., the synthesis of the highly active additive could be obtained in 1 to 2 hours even when ethylamine or propylamine was used. In the case of ethylamine, it was found that the synthesis of the highly active additive could be obtained. It was found that the synthesis of a highly active additive can be obtained in about 0.5 hours.
