Description

The combusitive liquid mixed with the Bio or Methanol and water}

Water has the chemical symbol H ₂ O and is colorless and transparent under standard conditions (STP: 25 1 atm), covering as much as 70% of the earth's surface, while fossil fuels reduce the development of alternative fuels ( Vessel, boiler, industrial, agricultural, household).

This technology focuses on the fact that water and bio or methanol dissolve well and CO ₂ , N and S hardly occur compared to fossil fuels. It is a green technology considering the economical and eco-friendly aspect by mixing the mixing ratio of alcohol into 40 to 45 parts by weight and 50 parts by weight.

The exponential growth of the world's population and the rapid development of industry have led to the increase in energy consumption, which is why global economies have become the hot topic of low carbon green growth. Fossil fuels are about 300 years old, and crude oil is estimated to be exhausted in 2047, with only 35 years of crude oil, and natural gas is expected to be 55 years.

In addition, the environmental problems of the earth caused by the use of fossil fuels make the energy problem more difficult. The effect of saving energy by increasing its efficiency as a substitute for air pollution and existing energy caused by the problem of warming, NOx, SOx and CO emitted from automobiles and industrial boilers It is a technology that focused on the desperate need of technology to get the point.

As a result of recent research on mixed fuels, the technical example shows that the size of the aqueous phase is so large that microdispersion is not achieved to satisfy the physicochemical stability as an emulsified fuel. There was a problem with the phenomenon.

The present invention takes the 90 ~ 95 weight ratio of water and alcohol through the test results in consideration of this problem of the mixed fuel, the remaining 5 ~ 10 weight ratio by using a combustion accelerator, environmentally friendly, low cost, air pollution emissions Minimized.

The mixing ratio of water and alcohol is excellent in dissolving each other, but when the ratio of water is high, the flash point is increased and the calorific value is taken into consideration, and the additives that are the combustion promoters are combined to achieve chemical stabilization of alcohol and water.

In addition, the considerations of the stability of the mixture, stability of viscosity, solubility, intermolecular action and properties of the mixture, quality of the mixture, and the stability of the storage regardless of the ambient temperature were considered as considerations when mixing the mixed fuel. They dissolve well, and hydrogen bonding is more important than polarity, and water dissolves up to 4 carbons in water, and the more similar the molecular interactions are, the better the dissolution becomes.The energy is amplified by separation between solvent particles, the viscosity and surface tension Quality of mixed fuels depending on the conditions

The other types of fuel that can replace oil are as follows.

Biofuel fuel oil ; Biodiesel is produced by esterification of various renewable raw materials such as vegetable oil, animal fat, and waste cooking oil, and is called fatty acid methyl ester, which is similar to diesel oil. It can be used in the form of biodiesel oil mixed with 20% vegetable oil and 80% light oil.

Alcohol mixed fuel oil ; Alcohol and gasoline extracted from vegetable raw materials are mixed and used as fuel for automobiles, but are currently used in the form of imports from Korea.

Emulsified fuel oil ; It is a heavy fuel oil alternative fuel. It is manufactured as a blending ratio of 70% of heavy oil and alcohol, less than 30% of emulsifier and water, and is actively developed and used in Korea.

Due to the continued price increase of fossil fuels, mixing only water with alcohol for use in farming villages and general boilers does not cause ignition during combustion. Burning point

Water and oils are typical of those that do not mix with other liquids. However, these two unmixed liquids can be mixed by adding emulsifiers, which are difficult to keep stirring due to the phenomenon of oil and water separation, important problems of storage stability of the mixture and stability in the tank under the conditions of use, and also heavy manufacturing process. In order to lower the viscosity and induce the dispersion of the fluid, there was a need to increase the temperature during stirring. As a result, the mixed fuels to date have not been able to meet the objectives of chemical stability, pollution restriction, cost reduction and fuel consumption reduction.

However, the present invention solves the above problems by mixing 30 to 50 parts by weight of water with 40 to 65 parts by weight of methanol as a third energy source and 5 to 10 parts by weight of additives for smooth mixing and complete combustion. This focuses on the economics of sustained production as long as water prices do not rise as well as the price of oil, and the development of environmentally friendly alternative energy with little contaminants during combustion.

While global reserves of natural resources continue to decrease, civilization and industrial development require enormous energy sources, all of which are concentrated on alternative energy, one of the future growth engines, while methanol is now produced from natural gas. In addition, it is possible to produce bioethanol and biomethanol using biomass, so it can be regarded as a third energy source that can be easily supplied even in a natural fuel state and an artificial state.

It is a technology that can produce fuel by mixing the most common water with additives and methanol (bio), which is a physically and chemically stable structure and an eco-friendly alternative that generates little CO ₂ , N, or S without oil separation. There is a development effect on fuel. The effect can be summarized as follows.

First ; It is an environmentally friendly energy that can replace fossil fuels.

Second ; The use of water is very cheap compared to other fuels.

Third ; The procurement of raw materials is very easy, the manufacturing process is simple, and small scale operation is possible.

Fourth ; It can be used for ship, boiler, industrial, agricultural and home use.

Fifth ; The calorific value can be adjusted according to the mixing ratio

Sixth ; Establishing a firm commitment to low carbon energy policies

The main materials used in the present invention and the properties thereof are as follows.

Biomass : Biomass is the most used energy source in the world until the 19th century, when wood was the main energy source. Today, biomass supplies much of the energy in underdeveloped countries. Biomass is still abundant, and not only wood but also cereals, plants, crop residues, livestock manure and food waste can all be used for energy production as biomass. Biomass may be used to produce heat easily in raw form, such as wood, or processed to obtain liquid fuels such as methanol, ethanol, biodiesel oil, and biofuels such as gaseous fuels such as hydrogen or methane. It can also be used as fuel for automobiles, power generation and heating.

Many forms of biomass provide 11% of the world's primary energy. Biomass is currently the largest energy source producing 35% of primary energy in developing countries, and by the middle of next century, 90% of the world's population is expected to live in developing countries, which will remain an important global energy source. Biomass fuels are produced to allow for sustainable reproduction and, if used, will help meet new carbon emission standards at low cost without causing net increases in atmospheric carbon dioxide. In addition to conventional applications, it is also important to modernize biomass energy production systems in a variety of forms, including power, liquid fuel, and gas. Wood fuel is the main energy source for almost half of the world's population.

Methanol and water ( H ₂ O ) : According to the characteristics of the alcohol, the main composition of the present invention, the alcohol is a whole of the compound substituted with a hydroxyl group (-OH) of a hydrogen atom of a hydrocarbon consisting only of carbon (C) and hydrogen (H). do. Methanol (CH ₄ O) and ethanol (C ₂ H ₆ O) are both alcohols and have similar physical properties, such as boiling point and freezing point solvent, as can be seen in the molecular formula. By the way, they have similar physical properties, but biological activities are different, but the reason for defining one kind of material having the same property as a pure substance is that melting point, boiling point, certain point, and density are constant. Thus, in the present invention, the physical properties of methanol and ethanol are equally applied. An exemplary sample used in the present invention is methanol. Compared to petroleum, which is an underground resource, it is much less competitive than ethanol, and thus has a competitive edge compared to ethanol.

Methanol dissolves well in water because the methyl group and the ethyl group, that is, the nonpolarity and the presence of hydrogen atoms combined with oxygen, can easily hydrogen bond with water.

Solubility in water is infinite because the solubility of water in methanol is high for the above reasons.

A substance is a mixture of two or more pure substances of different nature. In other words, the ratio of mixing of the components is not constant, but the properties of the component materials remain intact. The nature of the mixture is a homogeneous mixture of melting point, boiling point, freezing point, and density, but evenly mixed with pure substances, depending on the proportion of the mixture. As shown in Table 1, the aqueous methanol solution with water and methanol is a homogeneous mixture. It is valuable as the main composition because there is not much phosphorus reaction.

In the present invention, 40 to 55 parts by weight of methanol and 30 to 50 water were stirred to form a main component of the mixed fuel. The problem is that the economical value of adding a lot of water, but the combination of water and methanol is very important, such as low calorific value as fuel, the higher the calorific value of methanol is higher.

In the mixed fuel of the present invention, the problems of the upper and lower classification and the freezing point of the cold season, which were the most problematic problems of the emulsified fuel, did not occur.

The freezing point of methanol is -97.8 and the freezing point of water is -0, but the freezing point of the mixed fuel sample is -43, which is considered to be proportional to the combination of water and methanol.

Acetone (C3H6O) : Acetone is the simplest form of ketone. It mixes well with most solvents such as water, alcohol, ether, etc., and is highly flammable because it is highly volatile at room temperature. Freezing point is -94.6 ℃, boiling point is 56.5 ℃, specific gravity is 0.792.

A representative compound produced from acetone is diacetone alcohol. Diacetone alcohol is used as a solvent, thinner, etc., and in real life, it is used to wash substances that are not easily washed with water such as paint because they dissolve well in both water and organic solvents.

Using methanol as an additive may increase the toxicity of acetone, but in small amounts it has no effect.

In the present invention, 2 to 7 parts by weight is added, but the amount of acetone can be adjusted according to the combination of water and alcohol, and plays an important role in increasing the calorific value.

Acetone is a slightly toxic but stable composition with a carcinogenic classification from ACGIH as A4 (not classified as a human carcinogen).

Hydrogen peroxide ( H ₂ O ₂ ) : From the physical properties of hydrogen peroxide, the melting point is 262.15 (-11 ℃), the boiling point is 423.35 (150.2 ℃), and the density is 1.4 g / cm3. Hydrogen peroxide is widely used in the production of bleaches, oxidants, derivatives, etc. It is colorless and transparent and has a characteristic smell similar to ozone.

Extremely soluble in water, aqueous solution dissociates slightly as a dibasic acid to give an acid. Distillation can be done in vacuo, but explodes in presence of impurities.

In particular, water and methanol are catalysts for fast chemical reactions, and when contacted with flammable materials, they can ignite and promote combustion.

In addition, since the desulfurization treatment with a strong oxidizing power is widely used in the environmental field, the mixed fuel reduces fuel device corrosion such as burners.

In the present invention, it is preferably used as a catalyst of water and alcohol by using a concentration of 45% or more in 1 to 3 parts by weight, especially in the case of high concentrations of 65% or more, since self-produced amount exceeds the heat loss to the surroundings, it explosively decomposes itself. do.

Other compositions are as follows.

Heptane, nitrobenzene, polyoxyethylene alkyl ether, rhodamine

Heptane ( C ₇ H ₁₆ ) : Heptane is an alkane-based hydrocarbon containing a large amount of oxygen and carbon. It is present in petroleum fuel and is a volatile and flammable liquid. In particular, by adding a compound containing a large amount of oxygen to induce complete combustion to increase the calorific value, it is used as a standard for preventing air pollution and preventing knocking of gasoline engines. In the present invention, 1 to 2 parts by weight to increase the complete combustion through the combination of volatile and oxygen

Nitrobenzene ( C ₆ H ₅ NO ₂ ) : An aromatic compound obtained by nitration of benzene with a mixed acid. Although insoluble in water, it is mixed well with an organic solvent and used as a solvent for organic reactions. It is also used as an oxidizing agent because it exhibits weak oxidation.

Nitrification is defined as a unit process for introducing one or two or more nitro groups into an organic compound, and a nitro compound generally refers to a compound having a structure in which a nitro group is bonded to carbon. Nitro compounds are mainly used for high performance supplements, but are also very useful as intermediates for the preparation of compounds by reduction (benzidine, p-aminophenol).

Nitrobenzene is a good solvent for organic materials and can dissolve many inorganic compounds. It is also sometimes used as a solvent for the reaction medium and recrystallization.

In the present invention, by adding 1 to 2 parts by weight, it reacts as a dissolution medium with any organic or inorganic compound, and in particular, it is possible to increase the calorific value through the reaction with alcohol.

Polyoxyethylene alkyl ether ( CH2CH2O ) : A surfactant refers to a compound that breaks down the interface of materials that are not mixed with each other and binds them into one material. Due to its molecular structure, it has a lipophilic compound that is easily soluble in oil and a hydrophilic group that is easily soluble in water. Therefore, it aggregates at the interface of the dispersed phase particles to reduce the interfacial tension between the dispersed phase particles and the continuous phase particles.

Polyoxyethylene alkyl ethers are nonionic surfactants. The main axis of nonionic surfactants is nonylphenol-based petrochemical by-products.

It has a -OH group as a surfactant which does not have a group which dissociates into an ion in aqueous solution. Although relatively hydrophilic, the molecule has ester, acid amide, and ether linkages.

In the present invention, a nonionic surfactant was selected according to the physical and chemical properties of the fuel, and more preferably, polyoxyethylene alkyl ether was selected to suit the amount of 0.5 to 2 parts by weight. Polyoxyethylene alkyl ethers having about 8 to 10 carbon atoms in the hydrogen group have good strong permeability to any kind of oils, and have excellent dispersibility and solubilizing ability because the surface tension is lowered and the dynamic properties are strong.

Rhodamine (rhodamine): as a basic dye of xanthan tingye rhodamine 6GCP, a red dye such as rhodamine B is similar to the chemical structure. 6GCP is present as ethyl ester after the reaction. Both are soluble in water and ethyl alcohol and have strong fluorescence. In addition, as a basic dye, the color is beautiful, fine and rich, and is used to 0.1 to 0,3 parts by weight of the present invention to represent the mixed fuel color in red to have a unique brand of mixed fuel.
