Description

TECHNICAL FIELD

[0001] The present application relates to the field of fuel additives or modifiers, in particular to a high-activity green detergent and a preparation method and application thereof. BACKGROUND

[0002] The detergent additive (detergent) belongs to the surfactant category, which is a dispersant added to fuel oil to not only control the formation of engine low-temperature component deposits, but also efficiently control the formation of fuel engine high-temperature component deposits. Mainly including: polyisobutylene amine fuel ashless detergent dispersant; polyisobutylene succinate, benzylamine, ashless phosphate; high molecular weight ashless dispersant; boron modified ashless dispersant, etc. The main function is to keep the engine clean, and the generated insoluble substances are in colloidal suspension state, so as not to further form carbon, paint film or sludge. Specifically, its functions can be divided into four aspects of acid neutralization, solubilization, dispersion and washing.

[0003] At present, the similar 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.

[0004] It can be seen that the existing detergent has the above-mentioned disadvantages and needs to be further improved. How to create a new high-activity green detergent for fuel oil, which not only has the effect of cleaning carbon, but also has the effects of increasing efficiency, saving oil and reducing emissions, 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 high-activity green detergent for fuel oil, a preparation method and application thereof, which not only has the effect of cleaning carbon, but also has the effects of increasing efficiency, saving oil and reducing emissions, so as to overcome the deficiencies in the prior art.

[0006] To solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0007] In a first aspect, the present application provides a high-activity green detergent, which comprises a stock solution and a diluent; the stock solution is a liquid substance formed by esterification reaction of 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid according to a weight ratio of 1.8-3:1; and / or the stock solution comprises 2-ethylhexanol, phosphite, acetic acid-2-ethylhexyl ester, polyisobutylene succinic anhydride and ethylhexyl phosphate; the diluent 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 is 0.8%-1.3%, and the balance is the diluent.

[0008] The 2-ethylhexyl phosphate is in liquid state, and its molecular formula is C24H54O8P2; the hydroxyethylidene diphosphonic acid is in dry powder state, and its molecular formula is C2H8O7P2. The structural formula of the 2-ethylhexyl phosphate is as follows:

[0009]

[0010] It usually exists in the form of a dimer, and its structural formula is as follows:

[0011]

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

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

[0014]

[0015] Both of the above two organic matters have the structure of phosphoric acid in structure, and therefore, according to the principle of similarity compatibility, the mixture can be dissolved in the state of heating, and the two organic matters both have relatively active carboxyl and hydroxyl, and therefore, an esterification reaction is generated.

[0016] After the heating reaction, the reaction products of the two organic matters basically contain 2-ethylhexanol, phosphite, acetic acid-2-ethylhexyl ester, polyisobutylene succinic anhydride, and residual 2-ethylhexyl phosphate which does not participate in the reaction.

[0017] The structural formula of the 2-ethylhexanol is as follows:

[0018]

[0019] The structural formula of the phosphite is as follows:

[0020]

[0021] The structural formula of the acetic acid-2-ethylhexyl ester is as follows:

[0022]

[0023] The structural formula of the succinic anhydride in the polyisobutylene succinic anhydride is as follows:

[0024]

[0025] 2-ethylhexanol and 2-ethylhexyl acetate are high molecular dispersants, which can promote the dispersion of the components in the fuel, and the result can form the full mixing of the fuel and oxygen in the air, and promote the full combustion. And the dispersion effect makes the fuel spray form a mist, which is more conducive to its full mixing and contact with the air. The oligomer water cluster is water with less water molecule aggregation, and its role is to cooperate with the above two additives to make the effective fuel fully dispersed and atomized, and to achieve the effects of efficiency, oil saving, carbon cleaning and emission reduction by changing the physical properties of the fuel. Formaldehyde is easier to burn than high-carbon alkanes, and under the participation of oligomer water clusters, it forms a "micro-explosion" effect, which further atomizes and disperses and promotes full combustion.

[0026] Phosphite and ethylhexyl phosphate play an antioxidant role in the mixture, and they can form a barrier film in the fuel combustion chamber to prevent oxidation components from corroding the walls, especially preventing the adhesion of carbon deposits to the walls. It can effectively inhibit the generation of high-temperature sludge, remove the carbon deposits generated in the oil circuit and the engine, make the oil circuit more unobstructed, atomize the fuel more fully, and save fuel.

[0027] There are two types of carbon deposits in automobile engines. One is some "sludge" deposited on the throttle, intake manifold and valve back, which is composed of colloidal substances (olefins) in the fuel, oil sprayed from the exhaust pipe and dust in the air. These deposits are located in the low-temperature part of the engine. The other type of carbon deposit is located in the combustion chamber, i.e. the high-temperature part. These carbon deposits are solid carbides produced by incomplete combustion of olefins in fuel. As the engine combustion process gradually deposits on the top of the piston and the cylinder head, these carbon deposits will cause the engine combustion chamber area to become smaller and cause knocking.

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

[0029] Based on the above mechanism, the original liquid can also be directly used with 2-ethylhexanol, phosphite, 2-ethylhexyl acetate, succinic anhydride and 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 2-ethylhexyl phosphate and hydroxyethylidene diphosphonic acid in a weight ratio of 1.8-3:1 to form an esterification reaction.

[0030] In a second aspect, the present application provides a preparation method of high-activity green detergent, 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 stock solution after the reaction; mixing and forming a dilute liquid by mixing formaldehyde with a content of >99% and oligomeric water clusters according to a weight ratio of 1:4-3:7; and mixing and stirring the stock solution and the dilute liquid, wherein the weight percentage of the stock solution is 0.8%-1.3%, and the obtained mixture is the high-activity green detergent.

[0031] 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 according to a weight ratio of 1.8-3:1 and stirring them uniformly; 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 stops heating and naturally cools to room temperature, and the substance in the kettle is in a liquid state, which is the stock solution.

[0032] 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 the powder to generate water, and maintaining for a period of time, and then continuously adjusting the reaction temperature to 110°C when no distilled water is generated and evaporated from the reaction kettle, and similarly evaporating the reaction water; the temperature is increased in sequence with a step of 10°C, and the final temperature is 220-230°C, and the water evaporation process is repeatedly performed.

[0033] In a third aspect, the present application provides an application of the high-activity green detergent as a fuel modifier, wherein the high-activity green detergent is the high-activity green detergent described above, or the high-activity green detergent prepared by the preparation method described above, and the fuel is gasoline or diesel.

[0034] Further, the fuel modifier is a fuel oil-saving modifier for saving fuel, and / or the fuel modifier is a fuel efficiency-enhancing modifier for improving the combustion efficiency of the engine and enhancing the power of the engine, and / or the fuel modifier is a fuel 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 fuel modifier is a fuel emission-reducing modifier for reducing exhaust pollution.

[0035] In a fourth aspect, the present application provides a fuel containing the high-activity green detergent described above or the high-activity green detergent prepared by the preparation method described above.

[0036] Further, the fuel is gasoline or diesel; 10-100 ml of the high-activity green detergent is added to 40-60 L of the fuel.

[0037] By adopting the technical scheme, the application has at least the following advantages:

[0038] (1) The high-activity green detergent is a pure petroleum product, and is a new fuel modifier without harmful elements (the product does not contain prohibited components, and does not contain sulfur, nitrogen, heavy metals, etc.).

[0039] (2) After the high-activity green detergent is added to the fuel, the physical properties of the fuel are changed, and the state of the oil molecules in the fuel is changed into a small molecule state, so that the liquid droplets atomized during combustion are finer and smaller, and are fully mixed with air, so that the fuel is fully combusted. 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 contact area between air and the oil molecules is increased, and more oxygen is released to participate in the combustion reaction. Due to the increase in oxygen content, the combustion is more complete, so that the engine combustion efficiency is improved, the engine power is enhanced, the emission of automobile exhaust pollutants is reduced, and the fuel is saved. At the same time, the product can clean the accumulated carbon produced by incomplete combustion, and no new accumulated carbon is generated, so that the cylinder is restored to be smooth, and the engine function is restored (idling instability, insensitive throttle, etc.).

[0040] (3) After the high-activity green detergent is added to the fuel, the quality of the fuel can be highly improved, and the road octane number or cetane number of the fuel is obviously increased. The fuel has good sensitivity, eliminates the engine resonance phenomenon, and the kinetic energy output is stable, so that the fuel consumption is saved by more than 10%. The fuel can realize full combustion of the oil in the engine, so that the emission of automobile exhaust pollutants is reduced. Test results show that the emission of carbon monoxide is reduced by 20%, the emission of particulate matter is reduced by 13%, and the compounds such as hydrocarbon and nitrogen oxide are also obviously reduced.

[0077] (4) Emission reduction

[0078] Table 2 Emission test results of diesel oil with high activity green detergent

[0079]
