Description
Technical Field
The invention relates to the technical field of fuel additives, in particular to a synergistic fuel additive and a preparation method thereof.
Background
One of the common problems in current fuel additive technology is the often inclusion of metal catalysts. These metal catalysts can play a role in improving combustion efficiency and reducing exhaust emissions in the combustion process. However, the use of fuel additives containing metal catalysts can cause damage to engine components, especially in long term use. The metal catalyst may chemically react with deposits inside the engine, resulting in increased deposits and wear of parts, which in turn affect the performance and life of the engine.
The patent technical document CN107312579B discloses a fuel additive which is efficient, energy-saving and power-improving, and the invention uses methyl ferrocenyl methyl alcohol and polyvinyl methyl ether as combustion improver according to the weight ratio of 1:1-3. The patent technical document CN112899045B discloses a composite plateau cleaning fuel oil additive, which is prepared by compounding an oxygen-containing organic compound and an organic metal catalyst as a fuel oil synergist. Although the introduction of the organic metal catalyst can make up for the problem that the oxygen-containing organic compound itself has limited capability of improving the fuel combustion efficiency, the metal ions can damage a spark plug released by gasoline and accumulate at the ignition position of the spark plug, and the metal ions can pollute a three-way catalytic converter of an engine so as to lose the catalytic effect of the three-way catalytic converter.
Disclosure of Invention
Therefore, the invention aims to provide a synergistic fuel additive and a preparation method thereof, so as to solve the problem that the traditional fuel additive often contains a metal catalyst, thereby damaging parts in an engine.
Based on the purposes, the invention provides a synergistic fuel additive, which comprises the following raw materials in parts by weight: 80-100 parts of base oil, 10-15 parts of dimethyl carbonate, 5-8 parts of diethyl carbonate, 1-5 parts of oxygen-enriched agent, 5-10 parts of polyether amine, 2-4 parts of polyacrylate, 1-5 parts of catechol and 0.5-1 part of polyisobutylene polysuccinimide.
Wherein the oxygen-enriched agent is obtained by dispersing an oxygen-enriched porous organic polymer in absolute ethyl alcohol;
wherein the oxygen-enriched porous organic polymer is obtained by adsorbing oxygen by a porous organic polymer formed by hydroquinone and dimethanol formal under the catalysis of anhydrous ferric chloride.
Preferably, the base oil is a mixture of C10-C13 alkanes, cycloalkanes, and aromatics.
Preferably, when applied to gasoline, the weight ratio of the C10-C13 alkane, the naphthene and the aromatic hydrocarbon is 50:40:10.
Preferably, when applied to diesel fuel, the weight ratio of the C10-C13 alkane, the naphthene and the aromatic hydrocarbon is 70:20:10.
Preferably, the cycloalkane is one or a mixture of several of cyclobutane, cyclopentane, cyclohexane and cycloheptane.
Preferably, the aromatic hydrocarbon is one or a mixture of several of toluene, xylene and ethylbenzene.
Preferably, the porous organic polymer and absolute ethanol are 1-5:10-50.
Further, the invention provides a synthesis step of the oxygen-enriched porous organic polymer, which comprises the following steps:
s1: adding hydroquinone into dichloroethane, adding dimethanol formal and anhydrous ferric chloride, stirring at 45-50deg.C for 5-7h, heating to 90-95deg.C, stirring for 20-24h, filtering, washing, and drying to obtain porous organic polymer;
s2: placing the porous organic polymer in an oxygen atmosphere with the pressure of 2-4MPa for 10-20min to obtain the oxygen-enriched porous organic polymer.
Preferably, in the step S1, the weight ratio of hydroquinone to dichloromethane to dimethanol formal to anhydrous ferric chloride is 1-5:2-10:3.1-15.5:0.1-0.5.
Further, the invention provides a preparation method of the synergistic fuel additive, which comprises the following steps:
(1) Mixing C10-C13 alkane, cycloalkane and aromatic hydrocarbon, and stirring at 300-600rpm for 5-10min to obtain base oil;
(2) Adding the oxygen-enriched porous organic polymer into absolute ethyl alcohol, and stirring for 3-5min at the rotating speed of 150-300rpm to obtain an oxygen-enriched agent;
(3) Adding dimethyl carbonate, diethyl carbonate, polyether amine, polyacrylate, catechol and polyisobutylene polybutylene imide into base oil, stirring for 10-20min at 500-700rpm, adding oxygen-enriched agent, and stirring for 3-5min at 150-300rpm to obtain synergistic fuel additive.
The invention has the beneficial effects that:
no metal catalyst: compared with the problem that the traditional fuel additive contains a metal catalyst, the additive does not contain the metal catalyst, and the damage risk of the metal catalyst to engine parts can be avoided.
The combustion efficiency is improved: the fuel additive added with the oxygen-enriched agent can improve the combustion efficiency, ensure that the fuel is fully combusted in the engine, reduce the waste and incomplete combustion phenomena of the fuel, and improve the fuel saving rate of the fuel.
Cleaning and preventing carbon deposition: the components in the additive have the functions of cleaning the combustion chamber and preventing carbon deposition, can effectively reduce the generation of sediment and carbon deposition in the engine, keep the clean state of the engine and improve the combustion efficiency and the fuel saving rate.
The applicability is wide: the base oil used in the present invention may be a mixture of C10-C13 alkanes, cycloalkanes, and aromatics. The weight ratio of C10-C13 alkane, naphthene and aromatic hydrocarbon can be adjusted according to the requirements of different fuel types, so that the additive is suitable for different types of fuels such as gasoline, diesel oil and the like.
In summary, the synergistic fuel additive of the invention has the functions of improving combustion efficiency, cleaning a combustion chamber and preventing carbon deposition, thereby improving the fuel saving rate of fuel, and being free of metal catalyst and beneficial to protecting engine parts.

Performance test:
specific surface area:
oil saving rate: the mass Langish with the displacement of 1.6L 2012 is taken as a test vehicle, 92# oil and 92# oil of the embodiment 1-3 and the embodiment 1-3 are respectively added, the addition amount of the embodiment 1-3 is 1.5% of the weight of the 92# oil, the test vehicle runs on a rotating hub according to the same working condition for 100km respectively, then the test vehicle is tested according to NEDC circulation working condition, the fuel saving rate is respectively calculated according to the comparison of different fuel consumption results, and the results are shown in Table 1.
Carbon deposition amount: bench test was performed with a brand new national v gasoline engine (homemade EA 211), respectively adding 92# oil and 92# oil added with examples 1-3, comparative examples 1-3, the addition of comparative examples 1-3 being 1.5% by weight of 92# oil, the engine was disassembled after normal operation for 1000 hours under the established durable cycle conditions, and the engine combustion chamber carbon deposit was completely cleaned and weighed, the results are shown in table 1.
TABLE 1 Performance test results
| Oil saving rate/% | Carbon deposition amount/g | |
| Example 1 | 15.2 | 0.19 |
| Example 2 | 16.3 | 0.17 |
| Example 3 | 16.9 | 0.15 |
| Comparative example 1 | 8.6 | 0.32 |
| Comparative example 2 | 9.5 | 0.31 |
| Comparative example 3 | 14.5 | 0.24 |
| Comparative example 4 | 16.7 | 0.96 |
| 92# oil | - | 0.43 |
Data analysis: as can be seen from examples 1-3 and the pure addition of 92# oil, the synergistic fuel additive prepared by the invention has excellent fuel saving rate and can greatly reduce carbon deposition. It can be seen from example 2 and comparative examples 1-3 that the addition of the oxygen-rich agent greatly increases the fuel saving rate of the synergistic fuel additive, mainly because the oxygen-rich agent makes combustion more sufficient and efficient by increasing the oxygen supply at the time of combustion. This reduces the waste and incomplete combustion of the fuel as it enters the engine, reduces the formation of carbon deposits, increases the fuel utilization, and thus saves fuel consumption, and the substitution of hydroquinone with phenol in comparative example 2 has a greatly reduced effect, probably due to the absence of the formation of porous organic polymers from phenol or the reduction of hydroxyl groups, resulting in a reduction of its stored oxygen.
As can be seen from example 2 and comparative example 4, the oxygen-enriched agent employed in the present invention has an effect similar to that of the organometal compound and can be used in place of the existing metal-containing additives.
