Description

  The present invention is a supermolecular fuel obtained by mixing oil such as heavy oil A, kerosene, and light oil with water, and is not particularly in an emulsion (emulsified) state in which the oil and water are separated. The present invention relates to a method for producing an additive for producing a supramolecular fuel that does not increase environmental pollutants and a method for producing a supramolecular fuel using the additive.

  In recent years, research on so-called emulsion fuels, in which an appropriate amount of water is mixed with these fuels from the viewpoint of reducing environmentally hazardous substances such as CO2 emitted when using fossil fuels such as heavy oil A, kerosene, and light oil Has been actively conducted.

  However, conventional emulsion fuels are difficult to stockpile and transport due to separation of fuel and water. In addition, it has various drawbacks and problems such as a decrease in combustion temperature and calories due to the influence of water content, a decrease in fuel consumption due to a decrease in thermal efficiency, and corrosion in the combustion chamber.

  Even though these factors overlap and research and development have been repeated for decades, emulsion fuel has not been popularized in the market.

  The present invention has been devised to solve the above problems in view of the above problems, and the object of the present invention is to separate oil and water into a uniform mixed and fused state, and An object of the present invention is to provide a method for producing an additive for producing a supramolecular fuel capable of enhancing combustion efficiency and reducing environmental load substances, and a method for producing a supramolecular fuel using the additive. And

  The additive for producing supramolecularized fuel of the present invention mixes oil such as A heavy oil and water, so that oleic acid is 68.6% -75.2%, methanol 12.3% -14.1%, linole It contains 3.0% to 3.8% acid, 6.8% to 8.6% propylene glycol, and 4.0% to 5.5% ammonia.

  In the method for producing an additive for producing a supramolecular fuel according to the present invention, 68.6% to 75.2% of oleic acid is put into a stirrer, and then 12.3% to 14.1% of methanol is put into a stirrer. Next, 3.0% to 3.8% of linoleic acid is put into a stirrer, and then 6.8% to 8.6% of propylene glycol is put into the stirrer and stirred and mixed, and 4.0% to 5.5 of ammonia. And 5% in a stirrer and stirring and mixing.

  The method for producing a supramolecular fuel according to the present invention comprises a step of stirring and mixing 15% to 25% of the above additive for producing a supramolecular fuel and 50% to 60% oil, and 20% to 30% water. With stirring and mixing.

  The additive for producing a supramolecular fuel according to the present invention makes it possible to atomize water particles and mix them uniformly in the oil without any unevenness. And will not separate even if left for a long period of time.

  In the supramolecular fuel, water is completely dissolved in the oil, and it becomes a state close to complete combustion at the time of combustion. Therefore, thermal efficiency does not decrease and generation of environmental load substances such as CO 2 can be suppressed.

  The biggest cause of separation of oil and water is that the surface tension of the two is extremely different, but the surface tension of oil and water is made almost the same if the additive for supramolecular fuel of the present invention is used. As a result, separation of water and oil can be prevented.

  The additive for producing a supramolecular fuel according to the present invention is as described above. First, the production method will be described.

  The oleic acid (Oleic Acid), which is the main component of the additive for the supramolecular fuel of the present invention, is placed in a stirrer at a weight ratio of 68.6% to 75.2%, and then methanol is added at a weight ratio of 12%. .3% to 14.1%, then linoleic acid in a weight ratio of 3.0% to 3.8% and then propylene glycol in a weight ratio of 6.8% to 8.6%. Put in a stirrer and stir for 5-10 minutes to mix.

  Arbitrary and publicly known stirrers are used. In this production method, simple agitation is performed by simply circulating with a circulation motor.

  Next, ammonia (Ammonium hydride) is mixed at a weight ratio of 4.0% to 5.5% over about 30 minutes. At this time, heat generation starts after mixing, but it is important to add small amounts while keeping the heat generation at 52 ° C. or less. Although a bubble-like substance is generated during stirring, the generation of bubbles means the progress of a chemical reaction, and this disappearance means the end of the reaction.

  After the bubbles disappear, the mixture is stirred for 10 to 15 minutes.

  When the liquid temperature is 35 ° C. or lower after the final process is completed, the process is completed.

  The main properties of the raw materials, which are the five components used in the present invention, are as follows.

Appearance is a colorless gas at room temperature and normal pressure, and has a characteristic strong irritating odor. Since it dissolves well in water, it is often used as an aqueous solution (ammonia water).

  According to the above production method, oleic acid in a weight ratio of 68.6% to 75.2%, methanol 12.3% to 14.1%, linoleic acid 3.0% to 3.8%, propylene glycol 6.8% to An additive for producing a supramolecular fuel containing 8.6% and 4.0% to 5.5% ammonia is produced.

  The mixing ratio of the five components of the additive will be described. When a supramolecular fuel is produced using the additive (the production method will be described later), if oleic acid exceeds 75.2% by weight, the progress of emulsification slows down and the functions of other components are suppressed. It will be. Further, if it is less than 68.6%, sufficient emulsification cannot be achieved.

  When the methanol content exceeded 14.1%, the change in the surface tension of water and oil slowed down, and when it was less than 12.3%, the change in the surface tension was insufficient.

  When the weight ratio of linoleic acid exceeded 3.8%, the increase in the binding strength of water molecules slowed down, and when it was less than 3.0%, the binding strength was insufficient.

  When propylene glycol exceeds 8.6%, the modifying action of the additive slows down, and when it is less than 6.8%, the modifying action of the additive is insufficient.

  When ammonia exceeds 5.5%, the ester action of methanol was slowed down, and when less than 4.0%, the ester action of methanol was insufficient.

  Next, a method for producing a supramolecular fuel, which is an oil / water mixed fuel, using the additive produced as described above will be described.

  First, an oil for mixing the additive and water is prepared. The oils targeted by the additive of the present invention are A heavy oil, kerosene, light oil, etc., and water can be mixed with these oils.

  First, the additive produced as described above is mixed into the oil by a stirrer similar to the stirrer for producing the additive, and the mixture is circulated and stirred. The stirring time is 5 minutes to 10 minutes. It is important to make the additive evenly and evenly distributed in the oil, so that water added thereafter can be dissolved in the oil.

  Next, water is added to the oil to which the additive of the present invention has been added and stirred well. The stirring time is preferably 10 to 15 minutes. Through the emulsion state (emulsified state) immediately after adding water, water is completely solubilized in the oil, and an oil / water mixed fuel having transparency is produced.

  As the additive of the present invention, normal tap water or well water can be used without any particular limitation on the type of water such as hard water and soft water.

  About each compounding ratio of oil, water, and the additive of this invention, it mixes by the ratio of oil: water: additive = 50-60: 20-30: 30-15-25, respectively by volume ratio.

  When mixing with water, it is preferable to mix a fixed amount as slowly as possible.

  The experimental results of various supramolecular fuels produced with the additive of the present invention will be described below.

  Table 1 shows a comparison after combustion results between the conventional fuel using A heavy oil and the supramolecular fuel of the present invention. The supramolecular fuel according to the present invention has a combustion efficiency higher than that of the conventional fuel, a small amount of environmental load substance emission, a low price / volume and an extremely excellent effect.

Next, Table 2 shows an example of a boiler combustion test.

  The above test is an example of a combustion test at a boiler company, and there are two types of fuel used: A heavy oil and supramolecularized fuel (55% A heavy oil, 20% additive, 25% water).

  Combustion temperature is about 6% for supermolecular fuel, 982 ° C, compared to 926 ° C for virgin A heavy oil. The fact that the above results were obtained despite the inclusion of 55% fuel and 25% water means improved combustion efficiency and thermal efficiency.

  It can be seen that supramolecular fuel compared to heavy fuel oil A reduces the discharge of environmentally hazardous substances despite an increase in combustion temperature and calories.

The results of the combustion experiment can be summarized as follows.
Combustion in a boiler is combustion of fuel droplets, and fuel vaporized by a physical phenomenon on the surface of the fuel droplets and oxygen in the air form an air-fuel mixture that burns at various excess air ratios.
At this time, the water particles contained in the droplets are also heated by receiving the radiant heat due to this combustion, reach the boiling point, undergo micro explosions one after another, and secondary atomization occurs by scattering the surrounding oil droplets.
In this way, when the oil is instantly atomized, the contact area with the air is increased, complete combustion is rapidly performed, and generation of smoke and unburned carbon in the combustion exhaust gas is suppressed.
In addition, the increase in the contact area increases the energy saving effect because the excess air required for combustion can be kept low.

  In order to satisfy this condition, micronization of water particles is the most important. However, since water particles usually have a large surface tension, it is difficult to micronize water particles.

  Table 3 shows a comparison between the emulsion fuel and the supramolecularized fuel of the present invention.

  The supramolecular fuel according to the present invention has a high combustion temperature, combustion efficiency, and calories even when compared with conventional emulsion fuel, and does not lower fuel efficiency. Further, fuel and water can be stored and transported without being emulsified and separated, and there is almost no influence on the combustion engine such as corrosion.

  Since the additive for producing supramolecular fuel is an additive mainly composed of oleic acid, water particles can be minimized (nano-sized) to the limit. At the same time, it is not simply a mixture of oil and water, but water is dissolved in oil, so long-term stockpiling is possible.

  Although the present invention has been described above, the present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and the present invention has any configuration that has substantially the same configuration as the technical idea described in the claims of the present invention and that exhibits the same effects. It is included in the technical scope.
