Description
Technical Field
The invention belongs to the technical field of gasoline detergents, and particularly relates to a gasoline detergent synergist and a preparation method and application thereof.
Background
Along with the rapid growth of Chinese economy, particularly the high-speed growth of the conservation quantity of motor vehicles, the pollution in China is serious, the number of days of excellent air pollution indexes is obviously reduced, and the proportion of inhalable pollutants to main pollutants is larger and larger.
In addition, the gasoline in China is mainly catalytic cracking gasoline fraction, the content of olefin, especially diene, is relatively high, and the alkylation content is low, so that deposits are easy to generate by using domestic gasoline. The car using the unqualified gasoline has the problems of idle shake, noise increase, oil consumption increase, emission deterioration, difficult starting when serious, and even impossible starting. The root cause is that the unacceptable gasoline causes excessive engine sediment.
The gasoline detergent has the functions of inhibiting and removing engine sediment, can greatly improve starting performance, and can reduce pollutant emission to a certain extent. The addition of the detergent in the automobile fuel is an effective and practical important way for reducing the influence of sediment and automobile emission, and is an important measure for embodying the policy of 'in-front engine and out-of-front engine' for treating automobile emission pollution in China.
At present, the main stream gasoline detergent on the market mainly depends on the dispersion control carbon deposition of polyisobutene amine, polyether amine, mannich amine and the like to ensure that the efficiency of an engine is not reduced rapidly due to the accumulation of carbon deposition and prevent the incomplete combustion of the carbon deposition from causing the failure of tail gas to reach the standard, but basically, the detergent only delays the deposition of the carbon deposition, so that the efficiency of the engine is not reduced rapidly, and therefore, the detergent has limited effects of improving the power of the engine and purifying and decomposing the tail gas.
In order to effectively improve the engine efficiency of a motor vehicle by adding the gasoline cleaning synergistic agent on the basis of the inherent power of the engine, promote the decomposition of harmful substances in tail gas and reduce the emission of the harmful substances in the motor vehicle, a novel fuel cleaning synergistic agent meeting the environmental protection requirement is developed, so that the aims of saving more energy and purifying the tail gas are fulfilled, and the problem to be solved by the person in the field is urgent.

At present, a person skilled in the art selects to use a means for cleaning and dispersing carbon deposit to ensure the power of an engine. There is no precedent for introducing energy-containing materials into the gasoline detergent synergist, and the introduction of the energy-containing materials can improve the output power of the engine to a certain extent.
Preferably, the energetic material is a polynitrogen compound. The invention introduces the energy-containing material, in the combustion process of the engine, the decomposition of the energy-containing material can effectively improve the pressure of the engine and promote the full combustion of gasoline, thereby improving the power output of the engine, reducing the fuel consumption, and the full combustion of the fuel can reduce the carbon deposition and the content of harmful substances in the tail gas.
Further, the polynitrogen compound is hydrazine compound, nitro compound or nitrogen heterocyclic compound. The three compounds are more common and easy to obtain, are relatively more stable and safer from the viewpoint of operability, and have industrial realization prospect.
Furthermore, the number of nitrogen atoms in the molecular formula of the multi-nitrogen compound is more than or equal to 2. The more the number of nitrogen atoms, the larger the energy, the more the number of free radicals generated by the decomposition reaction, and the N generated by the decomposition 2 The greater the isopipe pressure. The energy of only one nitrogen in the molecular formula of the polynitrogen compound is too low to be suitable as the energetic material of the present invention.
Preferably, the detergent dispersant is formulated from one or more of polyisobutene amine, polyether amine or mannich amine detergent dispersants.
Preferably, the catalytic combustion improver is an exhaust gas purification ternary catalytic combustion improver.
Further, the catalytic combustion improver is an oil-soluble rare earth compound. The rare earth metal has a certain catalytic action on tail gas purification, and the oil-soluble rare earth can be well dispersed in the cleaning synergistic agent.
Still further, the oil-soluble rare earth compounds include, but are not limited to, cerium iso-octoate or lanthanum iso-octoate.
Researchers have proposed the use of rare earths to prepare or modify automotive exhaust gas purifying catalysts, but the art has not directly added rare earths to the application of gasoline cleaning synergists. The invention introduces trace rare earth metal elements to cooperate with the catalyst in the three-way catalyst, so as to achieve better tail gas purification effect.
The invention also provides a preparation method of the gasoline detergent synergist, which comprises the following steps:
adding the energetic material, the detergent dispersant, the catalytic combustion improver and the solvent oil into a stirring kettle according to a certain proportion, stirring and mixing uniformly, and filtering by a filter screen with the particle size of more than or equal to 1000 meshes to obtain a clear and transparent gasoline detergent synergist product.
The prepared gasoline detergent synergist can be used as a gasoline additive, the addition amount is 200-1000ppm, the gasoline combustion power can be improved, and the pollutant emission in the tail gas of an engine can be effectively reduced.
The beneficial effects are that:
the invention creatively introduces the energetic material, and in the combustion process of the engine, the decomposition of the energetic material can instantaneously generate a large amount of free radicals, can effectively promote the full combustion of gasoline, and simultaneously decompose N generated 2 The gases can also increase the pressure of the engine and the power output of the engine, thereby reducing the fuel consumption, and the full combustion of the fuel can also reduce the carbon deposition and the content of harmful substances in the tail gas. In addition, the catalytic combustion improver is introduced, enters the three-way catalyst along with the tail gas, and the trace rare earth metal elements cooperate with the catalyst in the three-way catalyst to achieve better tail gas purifying and decomposing effects, so that the content of tail gas emission pollutants is further reduced.

4. The detergent builder as claimed in claim 3, wherein the number of nitrogen atoms in the molecular formula of the polynitrogen compound is not less than 2.
5. The gasoline detergent builder of claim 1, wherein the detergent dispersant is formulated from one or more of a polyisobutene amine, a polyether amine, or a mannich amine detergent dispersant.
6. The gasoline detergent builder as claimed in claim 1, wherein the catalytic combustion improver is an exhaust gas purifying three-way catalytic combustion improver.
7. The gasoline detergent builder of claim 6 wherein the catalytic combustion improver is an oil-soluble rare earth compound.
8. The gasoline detergent builder of claim 7, wherein the oil soluble rare earth compound includes, but is not limited to, cerium iso-octoate or lanthanum iso-octoate.
9. The method for preparing the gasoline detergent builder as claimed in claim 1, comprising the steps of:
adding the energetic material, the detergent dispersant, the catalytic combustion improver and the solvent oil into a stirring kettle according to a certain proportion, stirring and mixing uniformly, and filtering by a filter screen with the particle size of more than or equal to 1000 meshes to obtain a clear and transparent gasoline detergent synergist product.
10. Use of the gasoline detergent builder of any one of claims 1-8 in a gasoline additive.
