Description

Gasoline modifier, preparation method, application and clean environmentally friendly gasoline containing same Technical Field

[0001] The present invention 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 gasoline modifier. Background Art

[0002] The rapid increase in my country's vehicle ownership and the widespread use of electronically controlled direct fuel injection (EDFI) in engines are placing higher demands on fuel quality. Olefins and some heavy aromatics in gasoline are susceptible to oxidation and condensation reactions at high temperatures, further forming carbon deposits and gum in the engine, severely impacting engine performance and causing power loss, increased emissions, and increased fuel consumption. The engine's fuel nozzles, intake valves, and combustion chamber are the most vulnerable areas for deposit formation. Fourth-generation gasoline detergents, represented by polyisobutylene amine compounds, can effectively remove deposits formed in engine fuel injectors, intake valves, and other areas, but they inevitably increase combustion deposits. This is primarily due to the high thermal stability of the polyisobutylene group, which is resistant to decomposition at high temperatures. After the fuel enters the combustion chamber, some of the undecomposed detergent is adsorbed and accumulates on the combustion chamber's inner walls, forming deposits, which in turn increases the formation of carbon deposits in the combustion chamber.

[0003] Currently, similar additives (detergents) on the market are mostly chemical agents containing non-petroleum ingredients, which can be harmful to engines over time. Due to their single ingredient composition, their overall cleaning performance varies, failing to achieve a comprehensive cleaning and environmentally friendly solution. While some detergents can effectively remove deposits formed on engine fuel injectors, intake valves, and other areas, they inevitably increase combustion deposits.

[0004] Therefore, it is clear that the above-mentioned existing detergents still have inconveniences and defects, and are in urgent need of further improvement. How to create a new gasoline modifier that can not only achieve the effect of carbon removal, but also achieve the effects of increasing efficiency, saving fuel, and reducing emissions has become a goal that the industry needs to improve.

[0005] Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a new gasoline modifier, its preparation method, application and clean and environmentally friendly gasoline containing it, so that it can not only achieve the effect of carbon removal, but also achieve the effects of efficiency improvement, fuel saving and emission reduction, thereby overcoming the shortcomings of the existing technology.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a gasoline modifier comprising, by volume, 10-30 parts of 3# or 5# white oil, 5-30 parts of gasoline detergent synergist, and 40-85 parts of isooctyl alcohol;

[0009] The gasoline detergent synergist comprises a stock solution and a diluent liquid; the stock solution is a liquid substance formed by mixing 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid in a weight ratio of 1.8-3:1, heating and performing an esterification reaction; and / or the stock solution comprises 2-ethylhexanol, phosphite, 2-ethylhexyl acetate, succinic anhydride and ethylhexyl phosphate; the diluent liquid is formed by mixing formaldehyde with a content of >99% and oligomeric water clusters in a weight ratio of 1:4-3:7; the weight percentage of the stock solution in the gasoline detergent synergist is 0.8%-1.3%.

[0010] The 2-ethylhexyl phosphate is in liquid form with a molecular formula of C24H54O8P2; the hydroxyethylidene diphosphonic acid is in dry powder form with a molecular formula of C2H8O7P2. The structural formula of ethylhexyl phosphate is as follows:

[0011] It often exists in the form of a dimer with the following structural formula:

[0012] That is, the 2-ethylhexyl phosphate is in the form of a blend of a monoester and a dimer.

[0013] The structural formula of hydroxyethylidene diphosphonic acid is as follows:

[0014] The above two organic compounds both have phosphoric acid structures, so according to the principle of like dissolves like, the mixture can be dissolved when heated. Both organic compounds have relatively active carboxyl and hydroxyl groups, so an esterification reaction will occur.

[0015] After heating reaction, the two organic substances generate reactants which basically contain 2-ethylhexanol, phosphite, 2-ethylhexyl acetate, polyisobutylene succinic anhydride and the remaining ethylhexyl phosphate which does not participate in the reaction.

[0016] Among them, the structural formula of 2-ethylhexanol is as follows:

[0017] The structural formula of phosphite is as follows:

[0018] The structural formula of 2-ethylhexyl acetate is as follows:

[0019] The structural formula of succinic anhydride in polyisobutylene succinic anhydride is as follows:

[0020] 2-Ethylhexanol and 2-Ethylhexyl acetate are polymeric dispersants that promote the dispersion of gasoline components, resulting in thorough mixing of gasoline with oxygen in the air and promoting complete combustion. This dispersion also causes the gasoline to form a mist when sprayed, further facilitating its thorough mixing and contact with air. Oligomeric water clusters enhance the effects of these two additives, fully dispersing and atomizing the effective gasoline. By modifying the gasoline's physical properties, they achieve efficiency gains, fuel savings, carbon reduction, and emission reductions. Formaldehyde is more flammable than higher alkanes, and the presence of oligomeric water clusters creates a "micro-explosion" effect, further atomizing and dispersing the gasoline and promoting complete combustion.

[0021] Phosphite and ethylhexyl phosphate act as antioxidants in their mixture. Working together, they form an isolation film in the gasoline combustion chamber, preventing corrosion from oxidizing components, particularly carbon deposits. This effectively inhibits the formation of high-temperature sludge and removes carbon deposits from the oil circuit and engine interior, ensuring smoother fuel flow and more complete atomized combustion, thus conserving gasoline.

[0022] Polyisobutylene succinic anhydride can effectively control carbon deposits in the engine combustion chamber. The mechanism is that polyisobutylene succinic anhydride will adhere to the porous carbon deposits, destroy the carbon adhesion, and decompose the carbon deposits layer by layer.

[0023] In addition, the purpose of adding white oil is to form a protective film on the entire oil circuit wall, preventing the formation of carbon deposits, making the oil circuit more unobstructed and improving the atomization of gasoline. Moreover, white oil burns fully, does not produce carbon deposits, and reduces the emission of harmful substances.

[0024] The main function of isooctyl alcohol is to increase the octane number of gasoline, making the combustion efficiency of the mixed oil high and playing a positive role in energy conservation and consumption reduction of gasoline.

[0025] Based on the above-mentioned mechanism of action, the stock solution can also be directly made of 2-ethylhexanol, phosphite, 2-ethylhexyl acetate, polyisobutylene succinic anhydride and ethylhexyl phosphate. In this case, the content of each component is the same as the content of each component in the liquid substance formed as follows: 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid are mixed and heated in a weight ratio of 1.8-3:1 to form a liquid substance by esterification reaction.

[0026] In a second aspect, the present invention provides a method for preparing the above-mentioned gasoline modifier, comprising: mixing 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid in a weight ratio of 1.8-3:1, heating and performing an esterification reaction, wherein the liquid substance formed after the reaction is a stock solution; mixing formaldehyde having a content of >99% and oligomeric water clusters in a weight ratio of 1:4-3:7, and mixing to form a diluted liquid; mixing the stock solution and the diluted liquid, wherein the weight percentage of the stock solution is 0.8%-1.3%, and the resulting mixture is a gasoline detergent synergist; and stirring the gasoline detergent synergist with 3# or 5# white oil and isooctyl alcohol in proportion and uniformly mixing to obtain the gasoline modifier.

[0027] Furthermore, the esterification reaction of mixing 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid in a weight ratio of 1.8-3:1 by heating includes: placing 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid in a weight ratio of 1.8-3:1 in a glass reactor and stirring evenly; the reaction starting temperature is 100°C, the final temperature is 220-230°C, the temperature is gradually increased in the middle, and the water evaporation process is repeated in multiple times; after the reaction is completed, the heating of the reactor is stopped and the temperature is naturally cooled to room temperature, and the substance in the reactor is liquid, which is the original solution.

[0028] Furthermore, the water evaporation process is repeated multiple times, including: first, adjusting the reaction temperature to 100°C, during which the powder is continuously stirred and slowly dissolved to produce water; after maintaining the temperature for a period of time, when no distilled water is produced and evaporated from the reactor, further increasing the reaction temperature to 110°C to evaporate the reaction water; and successively increasing the temperature in steps of 10°C to a final temperature of 220-230°C, and repeating the water evaporation process.

[0029] In a third aspect, the present invention provides an application of a gasoline modifier, wherein the gasoline modifier is the above-mentioned gasoline modifier; or the gasoline modifier prepared by the preparation method of the above-mentioned gasoline modifier.

[0030] The gasoline modifier is a gasoline fuel-saving modifier, which is used to save gasoline; and / or, the gasoline modifier is a gasoline efficiency-enhancing modifier, which is used to improve engine combustion efficiency and enhance engine power; and / or, the gasoline modifier is a gasoline carbon-removing modifier, which is used to clean carbon deposits generated by incomplete combustion inside the engine and prevent new carbon deposits from being generated; and / or, the gasoline modifier is a gasoline emission-reducing modifier, which is used to reduce exhaust pollution.

[0031] In a fourth aspect, the present invention provides a clean and environmentally friendly gasoline containing the above-mentioned gasoline modifier or the gasoline modifier prepared by the above-mentioned method for preparing the gasoline modifier.

[0032] Furthermore, 60-330 ml of gasoline modifier is added to every 40-60 L of gasoline.

[0033] Furthermore, the gasoline is 92# gasoline.

[0034] By adopting the above technical solution, the present invention has at least the following advantages:

[0035] (1) The gasoline modifier of the present invention is a pure petroleum product and a new type of gasoline modifier without harmful elements (the product does not contain prohibited ingredients, sulfur, nitrogen, heavy metals, etc.).

[0036] (2) After the gasoline modifier of the present invention is added to gasoline, it does not change any component index of the crude oil product, but only changes the physical properties of the oil product; it changes the state of the oil molecules in the crude oil product into a small molecule state, so that the droplets atomized during combustion are finer and smaller, fully mixed with air, and fully burned. The molecular weight distribution of the product is narrow, the viscosity is low, and the low-temperature performance is good. At a certain temperature, it decomposes into low-molecular olefins, forming a micro-explosion effect (secondary atomization), making the oil molecules smaller, increasing the contact area between air and oil molecules, and releasing more oxygen to participate in the combustion reaction. Due to the increase in oxygen content, the combustion is more complete, thereby improving the engine combustion efficiency, enhancing engine power, reducing the emission of automobile exhaust pollutants, and saving gasoline. At the same time, the product can clean the carbon deposits produced by the original incomplete combustion and no longer produce new carbon deposits, so that the cylinder body is restored to a clean state and the engine function is restored (such as unstable idling and insensitive throttle).

[0037] (3) After the gasoline modifier of the present invention is added to gasoline, it can achieve the effects of increasing efficiency, saving fuel, removing carbon and reducing emissions by changing the physical properties of gasoline; it can greatly improve the quality of gasoline, improve the sensitivity of gasoline, eliminate engine resonance, stabilize kinetic energy output, and save fuel consumption; it can achieve full combustion of fuel in the engine, thereby reducing automobile exhaust pollutant emissions.

[0078] (1) Carbon removal status

[0079] By comparison, it can be seen that conventional National VI standard 92# gasoline will produce carbon deposits after being used for a period of time; while the National VI standard 92# gasoline with the addition of gasoline modifier burns fully, which can clean up the carbon deposits produced by the original incomplete combustion, and no new carbon deposits will be produced, and the cylinder body will become smooth again.
