Description
Technical Field
The invention relates to the field of fuel additives, and particularly relates to a gasoline additive, a gasoline composition and a gasoline composition.
Background
Under the influence of poor quality of crude oil and backward refining process, the automobile gasoline has more unsaturated hydrocarbons, sulfur and nitrogen compounds, and is easily oxidized to form colloid in the storage and use processes, so that carbon deposit is easily formed at positions such as a nozzle, an air inlet valve, a combustion chamber and the like in the combustion process of the gasoline, further the problems of unsmooth oil supply, incomplete combustion, reduced maneuvering performance, increased oil consumption and the like of an engine are caused, and a large amount of harmful tail gas is discharged. Domestic and foreign researches show that the addition of the detergent into the gasoline is a practical and effective measure for improving the quality of the gasoline, improving the combustion efficiency of the gasoline and realizing energy conservation and emission reduction.
The gasoline additive in the current market is mixed with torpedo, so that the effect of removing carbon deposition is poor, and further development and improvement of a gasoline additive with better comprehensive performance are needed.
Disclosure of Invention
The invention provides a gasoline additive, a gasoline additive composition and a gasoline composition, which can remove carbon deposition generated by an engine system and inhibit the generation of new carbon deposition, so that the engine keeps a better working state, the energy consumption is reduced, the emission of automobile exhaust is reduced, and the fuel economy is improved.
A gasoline additive composition according to an embodiment of the first aspect of the invention comprises, in mass percent:
40-66% of dearomatized solvent oil with a flash point of more than 93 ℃, 4-10% of dipropylene glycol butyl ether, 20-50% of carbon deposition dispersing detergent, 2.5-10% of composite carbon deposition dispersing detergent and 3-6% of antifriction agent;
the carbon deposition dispersing detergent comprises one or more of polyetheramine and derivatives thereof, Mannich base and derivatives thereof, the rust rate of the composite carbon deposition dispersing detergent is not more than 2, the interface is not more than 1b, and the phase separation is not more than 2.
According to the gasoline additive composition of the embodiment of the first aspect of the invention, dearomatized solvent oil with a flash point of more than 93 ℃ and dipropylene glycol butyl ether solvent are used as diluting solvents, the flash point of the diluting solvents exceeds the requirement of the condition of safe transportation on the flash point of 93 ℃, the gasoline additive composition belongs to non-flammable chemicals, is convenient to transport, and simultaneously can increase the contact time of a carbon deposit dispersing detergent and stubborn carbon deposit due to non-instantaneous combustion during combustion due to the high flash point, so that the carbon deposit is removed more effectively; meanwhile, the carbon deposition dispersing detergent has higher content, is matched with a high flash point, obviously removes the carbon deposition, has obvious effect on removing the stubborn carbon deposition at the top of the piston, particularly has better effect on the direct injection type engine, and effectively solves the problem of poorer lubricity caused by the improvement of the cleanness of the fuel by the antifriction agent, thereby effectively reducing the oil consumption and showing the energy-saving effect of using the fuel additive.
Through reasonable proportioning, the high-content carbon deposit dispersing and cleaning agent can be uniformly dispersed in a diluting solvent, the compatibility of the later-stage gasoline additive composition in gasoline is improved, and meanwhile, the carbon deposit dispersing and cleaning agent is compounded, so that on one hand, the carbon deposit is removed in an auxiliary manner, and on the other hand, the demulsification property and the rust resistance of the whole gasoline additive composition can be effectively improved. Meanwhile, due to the addition of the friction reducer, the lubricity can be effectively improved, the oil consumption is further reduced, and the energy-saving effect is obvious.
It should be noted that in the gasoline additive composition according to the first embodiment of the present invention, the composite carbon deposition dispersing detergent needs to satisfy the national standard GB 19592 "motor gasoline detergent". Alternatively, the composite carbon distributed detergent has a tarnish ratio of 0, an interface of no more than 1b, and phase separation of no more than 2. For example, a product series such as UltraZol GA9020CS manufactured by Luobo corporation. And when the gasoline additive composition does not contain a rust inhibitor and a demulsifier, the gasoline additive composition has rust resistance and demulsification.
Wherein the rust ratio of UltraZol GA9020CS is 0, the interface is 1b, and the phase separation is 2.
The composite carbon deposition dispersing detergent can also be produced and sold by other manufacturers to meet the requirements and be suitable for the gasoline carbon deposition dispersing detergent or other disclosed composite carbon deposition dispersing detergents for the gasoline carbon deposition dispersing detergent, and the composite carbon deposition dispersing detergents can be mutually replaced. The composite carbon deposit dispersing detergent of the raw material satisfying the above requirements is not particularly limited.
The composite carbon deposition dispersing detergent has certain antirust property and demulsification property, and meets the requirements of different customers in order to further improve the antirust property and/or demulsification property. In some embodiments of the present invention in combination with the first aspect, the rust inhibitor is added in an amount of 0.1-1.6% by mass of the gasoline additive composition, for example, the rust inhibitor is added in an amount of 0.1%, 0.5%, 0.8%, 1%, 1.2%, 1.3%, 1.5%, or 1.6% by mass of the gasoline additive composition or a value in the range between any two points. The addition of the antirust agent can improve the antirust capability of the gasoline additive composition, prevent cylinder pistons and the like from being corroded, and can assist in preventing the generation of carbon deposition.
In combination with the first aspect, in some embodiments of the present invention, the demulsifier is added to the gasoline additive composition in an amount of 0.01 to 0.02% by mass, for example, the demulsifier is added to the gasoline additive composition in an amount of any one point or a range between any two points of 0.01%, 0.015%, 0.016%, 0.018%, and 0.02% by mass.
According to the second aspect of the invention, the gasoline additive composition comprises the following components in percentage by mass:
40-66% of dearomatized solvent oil with the flash point of more than 93 ℃, 4-10% of dipropylene glycol butyl ether, 20-50% of carbon deposition dispersing detergent, 3-6% of friction reducer, 0.1-1.6% of antirust agent and 0.01-0.02% of demulsifier;
the carbon deposition dispersing detergent comprises one or more of polyetheramine and derivatives thereof, Mannich base and derivatives thereof.
The gasoline additive composition provided by the second aspect of the invention takes dearomatized solvent oil with a flash point of more than 93 ℃ and dipropylene glycol butyl ether solvent as a diluting solvent, the flash point of the diluting solvent exceeds the requirement of the condition of safe transportation for the flash point of 93 ℃, belongs to a non-flammable chemical, is convenient for transportation, and simultaneously can increase the contact time of a carbon deposition dispersing detergent and stubborn carbon deposition due to the fact that the flash point is high and the combustion is not instantaneous, so that the carbon deposition is more effectively removed; meanwhile, the content of the carbon deposition dispersing and cleaning agent is high, the carbon deposition is obviously removed by matching with a high flash point, and the carbon deposition dispersing and cleaning agent has an obvious effect of removing stubborn carbon deposition at the top of the piston, particularly has a better effect when an engine is in a direct injection type, and further can effectively reduce oil consumption.
The reasonable raw material proportion enables high-content carbon deposition dispersing and cleaning agent to be uniformly dispersed in the gasoline additive composition, improves the compatibility of the gasoline additive composition added in the later period, and simultaneously adds the antirust agent and the demulsifier to improve the demulsification and antirust properties of the whole gasoline additive composition.
In combination with the second aspect, on the basis of the existence of the demulsifier and the antirust agent, the composite carbon deposition dispersing detergent with demulsification property and antirust property can be selectively added according to actual conditions, so that the cleaning performance, the demulsification property and the antirust property are further improved.
Specifically, for example, the gasoline additive composition further comprises a composite carbon deposition dispersing detergent with a rust rate of not more than 2, an interface of not more than 1b and phase separation of not more than 2, wherein the addition amount of the composite carbon deposition dispersing detergent accounts for 2.5-10% of the mass percent of the gasoline additive composition; for example, the amount of the composite carbon deposit dispersing detergent added is any one point or any value in the range between two points of 2.5%, 3%, 5%, 7%, 8% or 10% by mass of the gasoline additive composition.
In other words, the composite carbon deposition dispersing detergent needs to meet the national standard GB 19592 'automotive gasoline detergent', and can be used as long as the composite carbon deposition dispersing detergent meets the national standard GB 19592 'automotive gasoline detergent', so that the demulsification and rust prevention capability of the final gasoline additive composition can be improved in an auxiliary manner, and the carbon deposition removing effect can be further improved in an auxiliary manner. For example, the composite carbon soot dispersing detergent is commercial UltraZol 8829H, commercially available directly from Lobotun corporation.
Alternatively, the composite carbon deposition dispersing detergent has a rust ratio of 0, an interface of not more than 1b, and a phase separation of not more than 2, for example, a product series of UltraZol GA9020CS, which is a commercial product manufactured by Luoborun corporation.
The composite carbon deposition dispersing detergent can also be a composite carbon deposition dispersing detergent which is produced and sold by other manufacturers and meets the requirements and is suitable for gasoline carbon deposition dispersing detergent or other disclosed composite carbon deposition dispersing detergents suitable for gasoline carbon deposition dispersing detergent, and the composite carbon deposition dispersing detergents can be mutually replaced. The composite carbon deposit dispersing detergent of the raw material satisfying the above requirements is not particularly limited.
The composition combining the first aspect and the second aspect, namely, the composite carbon deposit dispersing detergent, the antirust agent and the demulsifier can be added independently or together, and finally, the demulsification property and the antirust property of the gasoline additive composition meet the national standard.
The addition of the dipropylene glycol butyl ether is combined with the dearomatization solvent oil with the flash point of more than 93 ℃ to form a diluent so as to uniformly disperse the carbon deposit dispersing detergent, the antirust agent and the demulsifier among the diluent, so that the stability is improved.
In combination with the first aspect and the second aspect, the carbon deposition dispersing detergent comprises one or more of polyetheramine and derivatives thereof, and mannich base and derivatives thereof, in other words, the polyetheramine and derivatives thereof, and the mannich base and derivatives thereof may be used independently or in combination, and all of them can achieve the effect of removing carbon deposition. The polyetheramine derivative is a derivative having the same carbon deposition dispersing and cleaning effect as the polyetheramine, and the mannich base derivative is a derivative having the same carbon deposition dispersing and cleaning effect as the mannich base. In the application, the molecular weight of the polyetheramine is 1000-1200, and the carbon deposition dispersing and cleaning effect in the range is good, and the matching effect with other components is good.
The Mannich base has excellent cleaning performance and compatibility, has antirust and antioxidant performance, can control the generation of deposits of low-temperature components of the gasoline engine, can effectively remove carbon deposition at high-temperature parts such as a piston and a combustion chamber, and can prevent the generation of the carbon deposition, thereby reducing the requirement on oil consumption. The mannich base and the derivative thereof can be purchased directly from the market, or can be prepared according to the existing preparation method and the existing equipment, and the source of the mannich base is not limited here.
The polyether amine can effectively control the deposits of a fuel system and an air intake system, and simultaneously effectively reduce the generation of carbon deposits of a piston, a combustion chamber and the like. The polyetheramines and derivatives thereof may be purchased directly from the market, or may be prepared by themselves according to conventional preparation methods and conventional equipment, and the sources thereof are not limited herein.
Since the commonly used lubricant friction reducer, such as common mineral base oil (SN150, silicone oil, castor oil, etc.), does not have sufficient friction reducing and lubricating effects on the piston friction pair under the high temperature combustion condition of the combustion chamber, and even increases the generation of carbon deposition in the combustion chamber, in order to avoid the above problems, and at the same time, the present invention is effective in energy saving, and in some embodiments, in combination with the first aspect and the second aspect, the friction reducer includes at least one of dialkylaminoalkanol compound, friction reducer H6457 produced by jaffon corporation, and friction reducer ultralzol 9525A produced by luobo corporation, so as to effectively reduce oil consumption and have a better energy saving effect.

Besides the D95 solvent oil and D100 solvent oil, the solvent oil can also be other dearomatized solvent oils which are sold in the market and have a flash point of more than 93 ℃.
In some embodiments of the present invention, in combination with the first aspect and the second aspect, the rust inhibitor includes one or more of T703, T706, T746, T747, span 80, and span 85, and has good compatibility with the above-mentioned diluent and the carbon deposit dispersing detergent, and also has good rust prevention effect.
In some embodiments of the invention in combination with the first and second aspects, the demulsifier comprises one or more of TD120, T1001, T1002, SP169 and BAKERT series demulsifiers. The BAKERT demulsifier is, for example, BAKERT9310 or BAKERT9372, and is not particularly limited herein.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
Through spot check and actual measurement, the existing gasoline additives on the market have low closed flash points, and most products do not meet the standard requirements of GB/T19592 gasoline detergent for vehicles. And the country has already banned the transportation of flammable hazardous chemicals, greatly restricting the development of gasoline additives. Therefore, the flash point of the product is improved by adopting the high-flash-point diluting solvent, so that the safe transportation requirement is met.
Another problem with fuel additives on the market is that the demulsification performance of a considerable number of products does not meet the requirement of the demulsification performance specification (phase separation) of not more than 2 of the national standard GB 19592 gasoline detergent for motor vehicles.
Another problem of the fuel oil additives on the market is that the rust resistance of a considerable number of products can not meet the requirement that the technical index (corrosion rate) of the rust resistance of national standard GB 19592 'automotive gasoline detergent' is not more than 5%.
Through investigation, the fuel additive in the market at present mainly has an effect on carbon deposition on a combustion system of an oil nozzle and an air inlet valve, and has no obvious effect on removing the carbon deposition in a piston combustion chamber.
Along with the improvement of the cleanliness of the gasoline quality (the changes of sulfur content reduction, olefin content reduction and the like), the lubricating property of the fuel is reduced, although the fuel additive meeting the national standard appears on the market, the carbon deposit generated by the engine can be reduced, the lubricating property of a piston friction pair in the engine combustion chamber is reduced, partial power is consumed, the oil consumption is not obviously reduced, and the energy-saving effect is not obvious; meanwhile, the inventor finds that the commonly used lubricating oil friction reducer, such as common mineral base oil (SN150, silicone oil, castor oil and the like), cannot play a sufficient friction reducing and lubricating role on a piston friction pair under the high-temperature combustion condition of a combustion chamber, especially a new generation of in-cylinder direct injection technology (the engine has a more compact structure and the temperature in the combustion chamber is higher), and even can increase the generation of carbon deposit in the combustion chamber.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
