Description

TECHNICAL FIELD

[0001] The present application relates to the field of gasoline modification, in particular to a gasoline modifier, a preparation method and application thereof, and clean and environmentally friendly gasoline containing the same. BACKGROUND

[0002] With the rapid increase of the number of automobiles in China, and the widespread use of electronic control fuel direct injection technology on engines, higher requirements are put forward for fuel quality. Because olefins and part of heavy aromatics in gasoline are prone to oxidation and condensation reactions at high temperatures, further generating carbon deposits and gum in the engine, which seriously affects the working condition of the engine, resulting in power reduction, emission increase and oil consumption increase. The fuel injection nozzle, intake valve and combustion chamber of the engine are the places where deposits are most likely to form. The fourth generation of gasoline detergents represented by polyisobutylene amine compounds can effectively remove the deposits formed in the fuel injection nozzle, intake valve and other parts of the engine, but inevitably increase the combustion deposits, the main reason being that the polyisobutylene group has high thermal stability and is not easy to decompose at high temperatures, and part of the undecomposed detergent is adsorbed and aggregated on the inner wall of the combustion chamber to form deposits, thereby increasing the formation of carbon deposits in the combustion chamber.

[0003] At present, the similar additives (detergents) on the market are mostly chemical agents containing non-petroleum components, which are harmful to the engine if used for a long time. Because the composition is single, the comprehensive cleaning effect is uneven, and the overall cleaning and environmental protection effect cannot be achieved. And part of the detergent can effectively remove the deposits formed in the fuel injection nozzle, intake valve and other parts of the engine, but inevitably increases the combustion deposits.

[0004] Therefore, the above-mentioned existing detergents obviously still have disadvantages and need to be further improved. How to create a new gasoline modifier that not only achieves the effect of cleaning carbon, but also achieves the effects of efficiency, oil saving and emission reduction has become the goal of the current industry that needs to be improved. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a new gasoline modifier, a preparation method and application thereof, and clean and environmentally friendly gasoline containing the same, so that it not only achieves the effect of cleaning carbon, but also achieves the effects of efficiency, oil saving and emission reduction, thereby overcoming the deficiencies in the prior art.

[0006] To solve the above technical problems, the present application adopts the following technical solutions:

[0007] In a first aspect, the present application provides a gasoline modifier, which comprises 10-30 parts by volume of 3# or 5# white oil, 5-30 parts by volume of a gasoline cleaning and efficiency improver, and 40-85 parts by volume of isooctanol.

[0008] The gasoline cleaning enhancer includes a stock solution and a dilution liquid; the stock solution is a liquid substance formed by mixing and heating 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid according to a weight ratio of 1.8-3:1 to perform esterification reaction; and / or the stock solution includes 2-ethylhexanol, phosphite, acetic acid-2-ethylhexyl ester, succinic anhydride and ethylhexyl phosphate; the dilution liquid is formed by mixing formaldehyde with a content of >99% and oligomeric water clusters according to a weight ratio of 1:4-3:7; the weight percentage of the stock solution in the gasoline cleaning enhancer is 0.8%-1.3%.

[0009] The 2-ethylhexyl phosphate is in a liquid state, and the molecular formula is C24H54O8P2; the hydroxyethylidene diphosphonic acid is in a dry powder state, and the molecular formula is C2H8O7P2. The structural formula of the ethylhexyl phosphate is as follows:

[0010]

[0011] It often exists in a dimer form, and the structural formula is as follows:

[0012]

[0013] That is, the 2-ethylhexyl phosphate is in a blend form of monoester and dimer.

[0014] The structural formula of the hydroxyethylidene diphosphonic acid is as follows:

[0015]

[0016] Both of the above two organic substances have the structure of phosphoric acid in structure, so according to the principle of similarity compatibility, the mixture can be dissolved under heating, and both of the two organic substances have relatively active carboxyl and hydroxyl groups, so that esterification reaction occurs.

[0017] After the heating reaction, the reaction products of the two organic substances basically include 2-ethylhexanol, phosphite, acetic acid-2-ethylhexyl ester, polyisobutylene succinic anhydride and residual ethylhexyl phosphate which does not participate in the reaction.

[0018] The structural formula of the 2-ethylhexanol is as follows:

[0019]

[0020] The structural formula of the phosphite is as follows:

[0021]

[0022] The structural formula of the acetic acid-2-ethylhexyl ester is as follows:

[0023]

[0024] The succinic anhydride structure in polyisobutylene succinic anhydride is as follows:

[0025]

[0026] The 2-ethylhexanol and the 2-ethylhexyl acetate are high-molecular dispersants, which can promote the dispersion of the components in the gasoline, and the result is that the gasoline can be fully mixed with the oxygen in the air to promote the full combustion. The dispersion effect causes the gasoline to be sprayed to form a mist, which is more conducive to the full mixing and contact with the air. The effect of the oligomeric water clusters cooperates with the above two additives to make the effective gasoline fully dispersed and atomized, and the efficiency, oil saving, carbon cleaning, and emission reduction effects of the gasoline are achieved by changing the physical properties of the gasoline. The formaldehyde is easier to burn than the high-carbon alkanes, and the "micro-explosion" effect is further formed under the participation of the oligomeric water clusters, which further atomizes and disperses and promotes the full combustion.

[0027] The phosphite and the ethylhexyl phosphate play an antioxidant role in the mixture, and they can cooperate to form a barrier film in the gasoline combustion chamber to prevent the corrosion of the oxidized components to the wall, and especially prevent the adhesion of the carbon deposit to the wall. The generation of high-temperature sludge can be effectively inhibited, and the carbon deposit generated in the oil circuit and the engine can be removed, so that the oil circuit is more unobstructed, the atomized combustion is more sufficient, and the gasoline is saved.

[0028] The polyisobutylene succinic anhydride can effectively control the carbon deposit in the engine combustion chamber, and the mechanism is that the polyisobutylene succinic anhydride can adhere to the porous carbon deposit, destroy the adhesion of the carbon, and make the carbon deposit layer-by-layer decompose.

[0029] In addition, the main purpose of adding white oil is to form a protective film on the entire oil circuit wall to prevent the generation of carbon deposit, so that the oil circuit is more unobstructed, and the atomization effect of the gasoline is better. Moreover, the white oil is fully combusted and does not generate carbon deposit, which reduces the emission of harmful substances.

[0030] The main role of the isooctanol is to increase the octane number of the gasoline, so that the combustion efficiency of the mixed oil is high, which positively promotes the energy saving and consumption reduction of the gasoline.

[0031] Based on the above-mentioned mechanism, the original liquid can also be directly used as the 2-ethylhexanol, the phosphite, the 2-ethylhexyl acetate, the polyisobutylene succinic anhydride, and the ethylhexyl phosphate. At this time, the content of each component is the same as that of each component in the liquid substance formed by mixing and heating the 2-ethylhexyl phosphate and the hydroxyethylidene diphosphonic acid according to a weight ratio of 1.8-3:1 to perform an esterification reaction.

[0032] In a second aspect, the present application provides a preparation method of the above-mentioned gasoline modifier, comprising: mixing and heating 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid according to a weight ratio of 1.8-3:1 to perform esterification reaction, and forming a liquid substance as a crude liquid after the reaction; mixing formaldehyde with a content of >99% and oligomeric water clusters according to a weight ratio of 1:4-3:7 to form a dilute liquid; mixing and stirring the crude liquid and the dilute liquid, wherein the weight percentage of the crude liquid is 0.8%-1.3%, and the obtained mixture is a gasoline cleaning synergist; and stirring and uniformly mixing the gasoline cleaning synergist, 3# or 5# white oil and isooctanol in proportion to obtain the gasoline modifier.

[0033] Further, the mixing and heating of 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid according to a weight ratio of 1.8-3:1 to perform esterification reaction comprises: putting 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid into a glass reaction kettle and stirring uniformly according to a weight ratio of 1.8-3:1; the initial reaction temperature is 100°C, and the final temperature is 220-230°C, and the temperature is increased in sequence and repeatedly evaporated in multiple times; after the reaction is completed, the reaction kettle is stopped heating, and naturally cooled to room temperature, and the substance in the kettle is in a liquid state, which is the crude liquid.

[0034] Further, the repeatedly evaporating in multiple times comprises: firstly adjusting the reaction temperature to 100°C, continuously stirring the powder during the reaction, and slowly dissolving and generating water, and after maintaining for a period of time, when no distilled water is generated and evaporated from the reaction kettle, the reaction temperature is continuously adjusted to 110°C, and the reaction water is also evaporated; the temperature is increased in sequence, and the final temperature is 220-230°C, and the water evaporation process is repeatedly performed.

[0035] In a third aspect, the present application provides an application of the gasoline modifier, wherein the gasoline modifier is the above-mentioned gasoline modifier, or the gasoline modifier prepared by the above-mentioned preparation method.

[0036] The gasoline modifier is a gasoline oil-saving modifier for saving gasoline, and / or the gasoline modifier is a gasoline synergistic modifier for improving the combustion efficiency of the engine and enhancing the power of the engine, and / or the gasoline modifier is a gasoline carbon cleaning modifier for cleaning the accumulated carbon generated by insufficient combustion in the engine and preventing the generation of new accumulated carbon, and / or the gasoline modifier is a gasoline emission reduction modifier for reducing exhaust pollution.

[0037] In a fourth aspect, the present application provides a clean and environmentally friendly gasoline containing the above-mentioned gasoline modifier or the gasoline modifier prepared by the above-mentioned preparation method.

[0038] Further, 60-330ml of the gasoline modifier is added to every 40-60L of gasoline.

[0039] Further, the gasoline is 92# gasoline.

[0040] By adopting the technical scheme, the present application has at least the following advantages:

[0041] (1) The gasoline modifier of the present application is a pure petroleum product, and is a new type of gasoline modifier without harmful elements (the product does not contain prohibited ingredients, and does not contain sulfur, nitrogen, heavy metals, etc.).

[0042] (2) After the gasoline modifier of the present application is added to gasoline, no component index of the original oil product is changed, and only the physical properties of the oil product are changed; the oil molecule state in the original oil product is changed into a small molecule state, so that the liquid droplets atomized during combustion are finer and smaller, fully mixed with air, and the product has a narrow molecular weight distribution, low viscosity, good low temperature performance, and is decomposed into low molecular olefins at a certain temperature to form a micro-explosion effect (secondary atomization), so that the oil molecules become smaller, the air contact area with the oil molecules is increased, and more oxygen is released to participate in the combustion reaction. Due to the increase of oxygen content, the combustion is more complete, thereby improving the engine combustion efficiency, enhancing the engine power, reducing the emission of automobile exhaust pollutants, and saving gasoline. At the same time, the product can clean the accumulated carbon produced by the original incomplete combustion, and no new accumulated carbon is generated, so that the cylinder body is restored to be smooth, and the engine function is restored (idling speed instability, throttle insensitivity, etc.).

[0043] (3) After the gasoline modifier of the present application is added to gasoline, the physical properties of the gasoline are changed to achieve the effects of efficiency improvement, oil saving, carbon cleaning, and emission reduction; the oil product quality can be highly improved, the oil product has good sensibility, the engine resonance phenomenon is eliminated, the kinetic energy output is stable, and the oil consumption is saved; the oil in the engine is fully combusted, thereby reducing the emission of automobile exhaust pollutants.
