Description
Technical Field
The present invention relates to an additive suitable for liquid fuels.
Background
With the continuous development of economy and the growth of population in China, the demand on petroleum resources is increasingly accelerated. But the petroleum resource crisis and the environmental pollution in the world are increasingly serious nowadays, and energy conservation and emission reduction become important subjects worldwide. Internal combustion engines powered by petroleum based fuels are currently facing significant challenges from conserving energy and meeting increasingly stringent emission requirements. In order to improve the quality and the combustion performance of the fuel oil and achieve the final purposes of energy conservation and emission reduction, the fuel oil is added with the energy-saving additive to play a role in catalyzing and supporting combustion, accelerate the combustion speed, enable the fuel oil to be completely released as far as possible, improve the utilization rate of the fuel oil, further reduce the oil consumption and reduce the emission of pollutants. The use of additives without changing the engine structure or adding other equipment devices is considered to be an optimal method for reducing emissions and improving economy.
In addition, gasoline has very strong volatility, fuel evaporation emissions exist in gasoline vehicle pollutants, and Hydrocarbon (HC) is a component of the gasoline vehicle pollutants, so that the gasoline vehicle pollutants have a pungent smell, carbon deposition is easily generated at parts such as an oil nozzle, oil injection is not smooth, the atomization quality of fuel oil is reduced, the fuel oil is difficult to completely combust after entering a combustion chamber, the engine is difficult to start, the idling is unstable, the oil consumption is increased, the exhaust emission is deteriorated, and the gasoline vehicle pollutants are particularly obvious in a low-temperature environment. Therefore, it is desirable to provide an additive which has low fuel consumption, reduces pollution of exhaust emissions, and promotes sufficient fuel combustion.
At present, novel combustion-supporting and energy-saving additives are researched in various countries in the world, and various energy-saving combustion-supporting products are researched, wherein the functions and the effects are different due to different types and components, but the general aim is to promote the complete combustion of fuels. Depending on the products of the catalytic combustion of the additive, it is generally divided into two categories: the additive is ash-containing additive containing metal or solid non-metal oxide, and the additive is ash-free additive containing pure organic matter. The ash type combustion improver can be divided into the following categories according to the metal characteristics: alkali metal salts (inorganic salts, organic salts) alkaline earth metal salts (inorganic salts, organic salts), oxides; transition metal salts, oxides; rare earth metal salts, oxides; noble metals and their organic complexes; the ashless energy-saving combustion improver contains no metal, and mainly comprises single organic matters or multifunctional composite organic matters substituted by oxygen-containing and nitrogen-containing hydroxyl, amino, carbonyl, carboxyl, ether bonds, ester bonds and other functional groups, such as aromatic, aliphatic, polymers and the like. The two additives have respective advantages, wherein the ashless energy-saving combustion improver has the greatest characteristic that no ash is generated after combustion and no secondary pollution problem exists, but the combustion-supporting effect of the ashless energy-saving combustion improver is not good if the ashless combustion improver is used, but the ashless combustion improver is good in effect, but the ashless combustion improver is easy to generate ash and easily causes secondary pollution. Therefore, at present, there is a need to develop a safe, energy-saving and environment-friendly additive which not only has a high-efficiency combustion-supporting effect, but also does not easily produce secondary pollution.

A method of preparing an additive suitable for use in liquid fuels, comprising the steps of:
mixing 100 parts by weight of higher aliphatic mono-alcohol and 1-100 parts by weight of ester compound containing 20-40 carbon atoms, stirring and reacting in a sealed container at 60-80 ℃ for 1-5 hours, and filtering to remove impurities to obtain the additive suitable for liquid fuel.
In the conventional classical combustion theory of a general internal combustion locomotive engine, fuel atomization is an important procedure, and according to the principle that the smaller the unit volume is, the larger the relative surface area is, the fuel is required to be rapidly combusted and fully combusted in a cylinder of the engine, so that the fuel supplied to the engine is oil mist with small granularity. When fuel oil is combusted, firstly, the fuel oil is vaporized into gas from liquid state, then the gas is mixed with oxygen in air to form combustible mixed gas, and the combustible mixed gas is combusted, wherein the conventional process that the fuel oil is vaporized into the gas state from the liquid state is called as a first atomization process, and usually, when fuel oil equipment is designed, a designer can carefully consider the problem, and the first atomization process is fully carried out through various means such as nozzle design, reflux heating design and the like, and the fuel oil can be completely and fully combusted only when the fuel oil atomization reaches the specified granularity standard. Objectively, if the fuel is sufficiently atomized, even if any additive is added, no fuel saving effect is produced because the fuel is sufficiently combusted.
However, any fuel equipment, including automobiles, cannot always be new, and components in the fuel system can be worn after long-term use, especially at the nozzles, valves, etc. At the moment, the one-time atomization effect of the fuel cannot meet the specified standard in the initial design, the fuel can be burnt incompletely, the fuel consumption can be obviously increased, and the emission is poor.
The alcohol compound is matched with the mesoporous material, acid and alcohol are esterified to a certain degree, the alcohol compound is greatly adsorbed on the surface of the mesoporous material, and the alcohol compound is quickly volatilized at high temperature to form high-temperature particles so as to impact large oil drops to generate a microexplosion effect and generate fuel oil particles with smaller particle size to form a secondary atomization effect, and finally large-particle oil drops exceeding the atomization standard are secondarily atomized into oil drops meeting the design standard, so that comprehensive microexplosion is generated in the combustion process to be fully combusted, and the combustion efficiency of the fuel oil in oxygen deficiency or equipment aging is improved.
The additive can save fuel consumption by 6-12%, can reduce the smoke intensity of diesel exhaust by 50-75%, can reduce PM50-75% of all engine exhaust, can reduce HC emission of all engine exhaust by 30-50%, and can reduce CO emission of all engine exhaust by 30-50%.
The above-described and other features, aspects, and advantages of the present application will become more apparent with reference to the following detailed description.
