Description

Composition of economizing fuel for adding combustion

The present invention relates to a fuel saving agent for combustion promotion, more specifically, 15 to 35 parts by weight of xylene, 20 to 35 parts by weight of ethanol, 10 to 20 parts by weight of isoparaffin, and normal heptane 5 based on 100 parts by weight of the total composition. A fuel additive comprising -20 parts by weight, 15-20 parts by weight of toluene, 1-5 parts by weight of isooctane, 1-10 parts by weight of hydrogen peroxide and 1-10 parts by weight of titanium dioxide, is added to any one of the fuel selected from gasoline, diesel and kerosene. The present invention relates to a fuel saving agent for combustion promotion that increases fuel efficiency by adding combustion.

The present invention relates to a fuel additive for combustion promotion comprising a combustion accelerator component. More specifically, the present invention is a fuel additive for combustion promotion which significantly reduces the generation of air pollutants and increases combustion efficiency by adding a fuel-based fuel selected from gasoline, diesel and kerosene as a main component and adding a supporting component to promote combustion. It is about.

Recently, many additives for promoting combustion in crude oil, gasoline, kerosene, diesel, heavy oil and petroleum coke have been developed and known. First, Korean Patent Publication No. 94-700487 discloses an example of using a polymer of oil-soluble polyolefin amine as a first component as an organic compound and C2-C6 mono-olefin as a second component as an additive for gasoline petroleum fuel. No. 94-701439 discloses oil soluble polymers of C2-C6 mono-olefins (eg polyisobutylene) and nitrogenous compounds having a molecular weight of less than about 1500. In addition, Korean Patent Publication No. 94-701440 discloses an example of using an additive including nitroxide or a precursor thereof. In addition, techniques for using various nitrogen-containing compounds as cleaning agents are known (Korean Patent No. 93-93). 11072, 94-8390).

This technology does not act as a catalyst in the direct combustion process because it only cleans the inside of the combustion chamber of valves and engines to increase combustion efficiency and reduces incomplete combustion, and it does not remain and is suitable for transport gasoline engines and diesel engines. However, it is more preferable that the accelerator remains in a combustor such as a boiler because the effect lasts for a long time. Inorganic compounds are treated with alkali in aqueous solutions of nitrates, sulfates, acetates or chlorides of iron or magnesium to adjust pH to 9-11 to produce fine particles of metal oxides or hydroxides, followed by naphthenic acid, tall oil fatty acid, petroleum sulfonic acid, etc. Examples of additives prepared by using petroleum hydrocarbons such as kerosene, light oil, normal or isoparaffin, and heavy oil as organic solvents are disclosed in Korean Patent No. 93-11927, and include oil-soluble alkali metals, alkaline earth metals or rare earths. Complex (Organic Metal Complexation

Compound) is disclosed in Korean Patent Application Publication No. 95-703630.

In addition, Korean Patent No. 92-1050 discloses organic peroxides and detergents that can be added to fuel tanks of gasoline or diesel engines (fatty amines, ethoxylated or propoxylated derivatives of fatty amines, fatty diamines, fatty imidazolines, polymers). A fuel additive composition comprising a mixture of at least one component of an amine and its derivatives with an organic carboxylic acid and other acids) and a hydrocarbon solvent is disclosed. In addition, in the case of emulsion oil using a surfactant in liquid fuel and water, a combustion-promoting additive composed of a solution obtained by mixing magnetic iron oxide, magnesium chloride, calcium chloride and the like with an alkali solution, hydroxide, sodium oleate and methanol It is disclosed in Korean Patent No. 89-2829, and an emulsion prepared by mixing a water-soluble alkali in water and an emulsifier for use in a high sulfur fuel is disclosed in Korean Patent No. 90-4506. The above known techniques have a problem in that the manufacturing method is complicated and expensive compounds are used, and when the oil-soluble peroxide is used, the effect is large only when the content is appropriate, and when the excessive amount is used, the fuel saving effect is rather lost. When inorganic compounds such as chlorides, iron compounds and alkali compounds are dispersed in fuel oil, there is a problem of precipitation of inorganic compounds due to the polarity difference between fuel and inorganic compounds, and when an alkali is used, anionic and cationic surfactants have a common ion effect and acidity. -There is a problem of precipitation due to the base neutralization reaction. Therefore, the present invention has tried to obtain a composition that can reduce the emission of air pollutants in proportion to the amount of addition without a problem in dispersion even if a large amount of the combustion-promoting additives relative to the amount of fuel.

An object of the present invention occurs during combustion when a small amount is added to gasoline, diesel used as fuel for automobiles, as well as kerosene, diesel, heavy oil, emulsion oil, petroleum coke mixed oil and waste oil refined oil used as heating and industrial fuel oil in the home. In order to reduce the generation of sulfur oxides and carbon monoxide among the air pollutants to increase the combustion efficiency to provide fuel additives for the promotion of combustion. This reduces energy costs and protects the atmosphere.

The present invention relates to a fuel additive for combustion promotion that significantly reduces the generation of air pollutants and increases combustion efficiency by adding a hydrocarbon-based fuel selected from gasoline, diesel and kerosene as a main component and adding a supporting component to promote combustion.

The present invention is 15 to 35 parts by weight of xylene, 20 to 35 parts by weight of ethanol, 10 to 20 parts by weight of isoparaffin, 5 to 20 parts by weight of normal heptane, 15 to 20 parts by weight of toluene, isooctane 1 A fuel promoting agent for combustion promotion, comprising: -5 parts by weight, 1-10 parts by weight of hydrogen peroxide, and 1-10 parts by weight of titanium dioxide. The fuel additive of the present invention is characterized in that any one fuel selected from gasoline, diesel and kerosene is used, and a fuel: fuel additive is mixed at 300: 1 with respect to the total weight ratio and combusted. In the present invention, the upper limit value and the lower limit value of the component are determined by precision experiments according to the particle difference between gasoline, diesel and kerosene, and determined by precision experiments according to the difference in the water content contained in the fuel additive.

The present invention is a mixture of ethanol, hydrogen peroxide and titanium dioxide, according to the type and quality of the fuel and the operating conditions of the furnace, the system and the degree of aging or by adjusting the composition ratio or by adding other alkali compounds such as potassium carbonate and calcium carbonate It can improve the thermal efficiency and air pollutant removal, remove chute, sludge and clinker of combustion engine and furnace, and clean the combustion engine such as wing of gas turbine. The present invention utilizes liquid hydrogen peroxide to improve conductivity, extend furnace life, and prevent corrosion of the furnace surface by removing clinkers and sludges in combustion engines and furnaces in combustion, increasing solubility and preventing corrosion of sodium hydroxide. Ethanol is used for this purpose.

The present invention stabilizes hydrogen peroxide by using titanium dioxide as a stabilizer, and when mixed, the decomposition of hydrogen peroxide is delayed even when heated to about 180 ° C as well as at room temperature. At the same time, the small amount of oxygen introduced into the furnace and combustion tubes by generator oxygen can easily burn fuel and burn carbon that burns less well than hydrogen. In addition, the present invention improves the cleaning ability by adding alkali compounds such as potassium carbonate and calcium carbonate to hydrogen peroxide, and inhibits corrosion at, for example, about 800 ° C. or more during combustion.

In addition, in the case of using the fuel additive of the present invention, it is possible to reduce SOx, an air pollutant, by using any one of gasoline, diesel, and kerosene and burning the fuel: fuel additive in a total weight ratio of 300: 1. . In addition, the fuel additive of the present invention is added to the heavy oil boiler to induce complete combustion of the fuel, thereby reducing the oil in the fly ash due to incomplete combustion of heavy oil, and to increase the dust collection efficiency of the dust collector and catalyst life, coal boiler In this case, induction of complete combustion can reduce dust and soot.

Ethanol added to the fuel additive of the present invention may serve to enhance the stability of hydrogen peroxide, delay the decomposition of hydrogen peroxide and simultaneously play a complementary role of inhibiting the coagulation of titanium dioxide. In addition, by adding an alkali compound such as potassium carbonate and calcium carbonate to the fuel additive of the present invention, it is possible to improve the soot during combustion, to control the NOx by inducing low-temperature combustion, and to improve the radiant heat conduction system during gas fuel combustion. This can lead to fuel savings.

The fuel additive of the present invention stabilizes hydrogen peroxide with ethanol, and thus does not decompose even when heated to about 180 ° C as well as room temperature, and active oxygen is generated when it is about 180 ° C or higher, thereby promoting combustion. The active oxygen generated using the fuel additive of the present invention burns incomplete carbon which burns fuel easily and burns less easily than hydrogen even if the amount of oxygen introduced into the furnace and the combustion engine is small. This has resulted in energy savings of about 15-25% in gasoline, diesel, kerosene and heavy fuel oils in fuel engines and thermal boilers. Furthermore, the fuel additive of the present invention induces complete combustion when used, thereby reducing the amount of incomplete combustion by about 85%, resulting in an energy saving of about 15-25%. The fuel additive of the present invention, when used, prevents corrosion in the furnace in the combustion state and removes chute, clinker and sludge to increase conductivity, extend furnace life, and increase the solubility of titanium dioxide using ethanol, rather than iron, copper, etc. For tools, tanks and furnaces, the corrosion protection is excellent. In the high-temperature combustion state, titanium dioxide begins to decompose at about 800 ° C and adheres to the furnace surface, forming a thin film of liquid state to suppress the formation of chute and clinker. At low temperatures ethanol and at high temperatures titanium dioxide and ethanol act to prevent corrosion. The fuel additive of the present invention has excellent cleaning ability due to the mixture of hydrogen peroxide and alkaline sodium hydroxide, and at the same time, it can suppress corrosion with ethanol and titanium dioxide, and can be applied to dust removal of gas turbine blades for special purposes, improving thermal efficiency, Excellent removal of contaminants such as chute and cleaning effect.

In the case of using the fuel additive of the present invention, any one selected from gasoline, diesel and kerosene is used, and the fuel: fuel additive is mixed with 300: 1 in a total weight ratio to burn about 500 ppm of SOx, which is an air pollutant, about 80 ppm. Reduced. In the case of the oil boiler of the present invention, the oil boiler induces complete combustion of the fuel, thereby reducing the oil dust in the fly ash due to incomplete combustion of the oil and extending the dust collection efficiency of the dust collector and the life of the catalyst. This reduced oil emissions by 84% at high loads.

Among the fuel additives of the present invention, xylene, isoparaffin, normal heptane, and toluene serve to increase the solubility and passivability of oversaline water and titanium dioxide, and gasoline, diesel, and kerosene delay the decomposition of hydrogen peroxide.

Combustion accelerator fuel additive was added to any one selected from gasoline, diesel and kerosene at a ratio of 300: 1 to measure the combustion promotion efficiency using a Kane-May KM9006 combustion analyzer (Kane International, UK). For the combustion test, the combustor purchases a commercially available oil boiler (Rinnai, model ROB 103T), with the Combustion Analyzer probe at the center of the flue 2 meters above the beginning of the year. The average value calculated after three measurements at minute intervals was recorded. The concentrations of air pollutants such as nitrogen oxides (NOx) and carbon monoxide (CO) tended to decrease slightly with the combustion operation time. At the beginning of combustion after ignition, the concentration of contaminants increases and then gradually decreases.

Comparative Example 1

Combustion analysis experiments were carried out in the same manner as in the example using purely commercial boiler kerosene (SK refinery) for heating.

Comparative Example 2

10 g of the mixed solution prepared by mixing 28 g of methyl alcohol, 32 g of Coree-NP-3 and 40 g of indoor kerosene (LG Caltex essential oil) were mixed with 990 g of boiler kerosene (SK essential oil), and the combustion analysis test was carried out in the same manner as in Example.

Comparative Example 3

0.2 g of sodium hydroxide was dissolved in 28 g of methyl alcohol, and 5 g of the mixed solution prepared by adding 32 g of Coree-NP-3 and 40 g of indoor kerosene (LG Caltex essential oil) was mixed with 995 g of boiler kerosene (SK essential oil).

Comparative Example 4

Combustion analysis test was carried out by adding a small amount of 1-pentanethiol to commercial boiler kerosene (SK refinery).

The results of the combustion analysis tests carried out in Examples 1 to 3 and Comparative Examples 1 to 4 were added to the boiler kerosene by adding the fuel additive for combustion promotion according to the present invention to significantly reduce the carbon monoxide generated, which was 30 compared to 70 ppm of kerosene. A reduction of 40% to 40% appears to result in less incomplete combustion. Increasing the amount of fuel additive for combustion promotion from 0.5% to 1.0% resulted in a slightly lower carbon monoxide generation. In addition, the combustion-promoting additive composition of the present invention to which hydrogen peroxide and titanium dioxide are added, the carbon monoxide reduction effect is greater than that of the comparative example. NOx showed similar values all within the margin of error. Sulfur oxides (SOx) were rarely generated at 0 ppm even in the combustion of gasoline, diesel and kerosene itself. Therefore, using a sulfur-containing fuel made by adding 1-pentanethiol, the same mercaptan compound as the form contained in crude oil to generate sulfur oxide, it was tested whether the combustion-promoting additive composition had a sulfur oxide reduction effect. The sulfur oxide (SOx) was reduced to 5.6 ppm when the fuel additive for combustion promotion according to the present invention was added, compared to 6.5 ppm of the comparative example. The temperature of the flue gas or flue slightly increased when the fuel additive for combustion promotion of the present invention was added, which is believed to be due to an increase in calorific value.

In addition, as a result of measuring fuel efficiency while driving a vehicle using the fuel accelerator for combustion promotion prepared in Examples 1 and 2, it was found that fuel economy was increased by 15 to 20%.
