The gasoline environmental-protection additive is low in cost and convenient in application, thereby improving the combustion efficiency of gasoline greatly, saving gasoline, reducing pollutant discharge and protecting environment. When in use, the gasoline environmental-protection additive of the invention is added into gasoline by 1-30% of the gasoline volume, thereby being very convenient.
Description
Technical field
The present invention relates to a kind of additive, particularly relate to a kind of gasoline environmental-protection additive.
Background technology
Improving the motor spirit cleanliness factor and gasoline is fully burnt is the problem that current chemical field and automotive industry are extremely paid close attention to, particularly in the gasoline that China adopts at present, the catalytically cracked gasoline proportion is also quite high, so gasoline oxidation generates colloid, paint film and sedimental problem also relatively seriously.Address this problem, except reducing in refinery is produced the peace and quiet gasoline of olefin(e) centent, adding additive in gasoline product also is method commonly used in the domestic and international chemical industry, as disclosed among CN1035115C, CN1046131C and the EP0654524A.
The disclosed a kind of gasoline composite additive of CN1035115C, by allyl butyrate imide, alkylphenol, benzotriazole derivative, thiadiazoles derivative, low mass molecule alcohol solubility promoter and oil lighting end solvent composition, can improve the cleanliness factor of gasoline, improve stabilization of gasoline, but rate of economizing gasoline is lower.
The disclosed multi-functional gasoline environmental-protection additive of CN1046131C composition comprises moisture adsorbent, carries oil, at least a purification agent and/or deposition agent, at least a antioxidant and/or metal passivator, at least a rust-preventive agent, at least a demulsifying agent; Can keep fuel air system cleaning, obvious fuel saving and minimizing exhaust contaminant content, but can not the fuel saving and the thing content that reduces pollution emissions.
The disclosed gasoline environmental-protection additive composition of EP0654524A comprises at least a ester, at least a detergent-dispersant additive, lubricant; This additive is owing to using the higher ester composition of price, so the cost height is difficult to promote.
Summary of the invention
Be directed to this, the objective of the invention is to, a kind of gasoline environmental-protection additive is provided, the efficiency of combustion of gasoline is improved greatly, fuel-economizing, it is few to discharge pollutants, environmental protection.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of gasoline environmental-protection additive includes the following composition of volume ratio:
Methyl tertiary butyl ether 2～10
Butanols 18～40
Methyl alcohol 500～990.
Preferably, the volume ratio of each composition is:
Methyl tertiary butyl ether 6
Butanols 20
Methyl alcohol 970.
Preferably, also to include volume ratio be 3～19 methyl cyclopentyl-dialkyl-tricarbon manganium to this gasoline environmental-protection additive.
Preferably, the volume ratio of each composition is:
Methyl tertiary butyl ether 6
Butanols 20
Methyl alcohol 970
Methyl cyclopentyl-dialkyl-tricarbon manganium 4.
Preferably, also to include volume ratio be 5～20 ethylenimine and 5～30 ethylene glycol to this gasoline environmental-protection additive.
Preferably, the volume ratio of each composition is:
Methyl tertiary butyl ether 6
Butanols 20
Methyl alcohol 970
Methyl cyclopentyl-dialkyl-tricarbon manganium 4
Ethylenimine 10
Ethylene glycol 15.
Preferably, described butanols purity is 〉=98%, and described methanol purity is 〉=99.99%.
Preferably, the purity of described hexahydroaniline is 〉=95%.
1, methyl tertiary butyl ether, english abbreviation are MTBE (methyl tert-butyl ether), are a kind of high-octane liquid, are the ideal blending components of producing unleaded, high-octane rating, oxygenated gasoline.It can not only effectively improve gasoline octane rating, and can also improve automotive performance, reduces CO content in the exhaust, reduces the gasoline production cost simultaneously.The chemistry oxygen level is much lower than methyl alcohol, is beneficial to warming up and fuel economy, and vaporization heat is low, and is favourable to cold start-up, is usually used in the blending of white gasoline and low lead oil.
MTBE is good gasoline high-octane rating additive and octane promoter, can arbitrary proportion dissolves each other and demixing phenomenon does not take place with gasoline, when being in harmonious proportion with gasoline component, good mediation effect is arranged, and the octane value that is in harmonious proportion is higher than its clear octane number.MTBE can significantly improve motor vehicle exhaust, if but the MTBE ratio that adds is not controlled, is made theoretical equivalent air-fuel ratio to exceed closed-loop control engine electronic control unit adaptive ability regulation range in one's power, then can the transformation efficiency of three-way catalytic converter be descended because of oxygen enrichment disturbs closed-loop control.The content of MTBE in the gasoline surpasses 7%, and the oxynitride in the motor vehicle emission can increase.MTBE has good chemical stability and physics stability, is difficult for generating superoxide in air, and MTBE toxicity is very low, in production and use, can not produce the problem of serious murder by poisoning HUMAN HEALTH.
2, methyl cyclopentyl-dialkyl-tricarbon manganium, english abbreviation are MMT (MethylcyclopentadienylManganese Tricarbonyl), are a kind of vehicle fuel additives, can improve the quality of fuel oil, reduce cost.MMT, the auxiliary octane promoter that can be used as tetraethyllead uses, and can improve gasoline effectively, the octane value of the gasoline that particularly high paraffinic hydrocarbon is formed.
The synthetic method of MMT; its concrete steps are: under nitrogen protection; in reactor, add tetrahydrofuran (THF) and sodium Metal 99.5; slowly drip fresh distillatory methyl cyclopentadiene (MCP) then; add the Manganous chloride tetrahydrate powder again, the reaction back will generate two methyl cyclopentadienyl manganese intermediates with underpressure distillation and separate, and again separated product be moved into autoclave; feed CO and carry out carbonylation, at last the product methyl cyclopentadienyl tricarbonyl manganese (MMT) that obtains is distilled purification.
Use methyl cyclopentyl-dialkyl-tricarbon manganium, have following advantage:
1, can improve gasoline quality effectively, improve gasoline octane rating, antiknock efficient height and addition is little, by ten thousand/add, the content of manganese is no more than 18 milligrams/L, can improve a gasoline 2-3 octane value (octane value by the metal unit weight is higher than more than two times of tetraethyllead).
2, incendivity is good, can with fuel together perfect combustion and do not produce the precipitation or residue, oil-saving effect is obvious;
3, have no side effect, other character of fuel is had no adverse effects;
4, easily dissolving at room temperature can be dissolved in gasoline and water insoluble;
5, stable in properties is not decomposed in air, and boiling point is higher, is difficult for vaporization losses;
6, nontoxicity does not pollute environment;
7, fusing point is low, is difficult for crystallization, is convenient to actual use.
Compared with prior art, cost of the present invention is low, and is easy to use, and the efficiency of combustion of gasoline is improved greatly, fuel-economizing, and few environmental protection discharges pollutants.
During use, 1%～30% adding of gasoline environmental-protection additive of the present invention according to the gasoline volume got final product, very convenient.
