Methanol

in the invention, the methanol can be used as gasolineThe oxygen content is increased, so that the fuel is fully combusted, thereby greatly reducing CO and NO in the atmosphere_xAnd the emission of harmful gases.

In the invention, the methanol is anhydrous methanol and is purchased from Jiangsu Qiangsheng functional chemical corporation.

Naphtha (a)

in the invention, the naphtha (naphthath) is one of petroleum products, also called chemical light oil, is light oil for chemical raw materials produced by processing crude oil or other raw materials, and is mainly used as reforming and chemical raw materials. Different distillation ranges exist due to different purposes, and the distillation range specified in China is from the initial boiling point to about 220 ℃. When the naphtha is used as a reforming raw material for producing aromatic hydrocarbon, a fraction at 70-145 ℃ is adopted and is called light naphtha; when the aim of producing high-octane gasoline is to adopt 70-180 ℃ fraction and weigh naphtha; when used as a solvent, is called solvent naphtha; naphtha or solvent naphtha was also weighed out for the aromatic solvent from coal tar.

In a preferred embodiment, the naphtha is a heavy naphtha using a 70-180 ℃ cut.

in a preferred embodiment, the organic alcohol amine is selected from one or more of monoethanolamine, diethanolamine, triethanolamine.

in a more preferred embodiment, the organic alcohol amine is monoethanolamine.

in the present invention, monoethanolamine, CAS number 141-43-5, was purchased from Ziboleivoro chemical Co., Ltd.

palm (palm)Oil

The palm oil is a tropical woody plant oil, is a plant oil variety with the largest production quantity, consumption quantity and international trade quantity in the world at present, is formed by squeezing palm fruits on an oil palm tree, and palm oil and palm kernel oil are produced from the palm fruits and the palm kernels respectively. Palm oil contains balanced saturated and unsaturated fatty acid esters, with 50% saturated fatty acids, 40% monounsaturated fatty acids, and 10% polyunsaturated fatty acids. The palm oil is rich in natural vitamin E and tocotrienol (600-1000mg/kg), carotenoid (500-700mg/kg) and linoleic acid (10%) which are beneficial to human health.

in the invention, the palm oil has CAS number of 8002-75-3 and is purchased from Wuhan Dahuawei pharmaceutical chemical Co.

In a preferred embodiment, the weight ratio of the organic alcohol amine to the palm oil is (2.5-5): 1.

In a more preferred embodiment, the weight ratio of monoethanolamine to palm oil is (2.5-5): 1.

in a most preferred embodiment, the weight ratio of monoethanolamine to palm oil is 4: 1.

according to the invention, the anti-knock property of the gasoline is improved by adopting the palm oil, but the anti-knock property is poor when the palm oil is added too little, and the viscosity is too high when the palm oil is added too much, so that the problems of carbon deposition and the like are caused. The inventor finds in research that the problem of poor low-temperature startability of gasoline can be solved when monoethanolamine is further used, and the inventor believes that the reason is that the amino group shows strong nucleophilicity due to the existence of hydroxyl group and amino group in the monoethanolamine molecule, and the alkanolamide generated by amidation reaction with palm oil has both lipophilic group and hydrophilic group, so that the alkanolamide has excellent low-temperature solubilization property, and can solve the problems of poor low-temperature startability of gasoline, delayed ignition and the like.

the inventor also unexpectedly finds that when the weight ratio of the monoethanolamine to the palm oil is (2.5-5): 1, the service life of the engine can be prolonged, and the inventor speculates that because the alkanolamide generated by the reaction of the monoethanolamine and the palm oil contains a large amount of long-chain alkyl, the acylamide has coordination effect and is easy to be attached to the surface of the engine to form a layer of hydrophobic protective film, so that the corrosion and swelling problems of the engine can be effectively avoided, the protection effect on the engine is certain, and the service life of the engine is prolonged.

Cosolvent

in the present invention, the cosolvent is an auxiliary agent for promoting dissolution, such as some solvents with the capacity of assisting/enhancing dissolution, and may also be some surfactants, dispersants, and the like.

in a preferred embodiment, the co-solvent is a non-ionic surfactant.

In a preferred embodiment, the nonionic surfactant is a combination of glyceryl monostearate and sorbitan monopalmitate.

In a more preferred embodiment, the weight ratio of glyceryl monostearate to sorbitan monopalmitate is (2-4): 1.

in a most preferred embodiment, the weight ratio of glyceryl monostearate to sorbitan monopalmitate is 3: 1.

in the invention, the glyceryl monostearate is purchased from Jiangsu Caosheng Biotech limited; the sorbitan monopalmitate is available from Nantong Jinlai, limited chemical industry.

methanol is a hydrophilic substance with stronger polarity, and gasoline is a weak-polarity lipophilic mixture mainly composed of various hydrocarbons, which are difficult to be mixed and dissolved, and a certain amount of cosolvent is adopted to treat the mixture. The inventor finds in research that after the nonionic surfactant is added, the hydrophilic group and the lipophilic group are tightly adsorbed on an oleyl alcohol interface, so that the surface tension can be effectively reduced, the Brownian motion between methanol liquid beads is blocked, the liquid beads are not easy to agglomerate and grow, and the intersolubility of methanol and gasoline is improved.

the inventors have also surprisingly found that when using glyceryl monostearate and sorbitan monopalmitate, and the weight ratio of glyceryl monostearate to sorbitan monopalmitate is (2 to 4): 1, the atomization performance of the gasoline can be obviously improved, and the inventor considers that the reason is that the viscosity of the palm oil is reduced due to the fact that the sorbitan monopalmitate is similar to the palm oil in structure, so that the system fluidity is obviously improved, and the problems of difficult atomization and incomplete combustion caused by easy blockage of a fuel nozzle are avoided; meanwhile, the glycerin monostearate refines a large gasoline molecular group microstructure, so that gasoline molecules can be uniformly mixed, the fine and smooth feeling is increased, and further the atomization performance of the gasoline is effectively improved.

antistatic agent

In the present invention, the antistatic agent is a chemical that guides/eliminates the accumulated harmful charges so that it does not cause inconvenience or harm to production/life, and is an additive that can reduce the accumulation of static electricity.

The antistatic agent is selected from one or more of cationic antistatic agent, anionic antistatic agent, zwitterionic antistatic agent and nonionic antistatic agent.

as the cationic antistatic agent, one or more selected from quaternary ammonium salts, fatty amines, or amine salts and derivatives thereof may be used.

the anionic antistatic agent may be one or more selected from sulfuric acid esters and salts thereof, phosphoric acid esters and phosphoric acid ester salts, and alkyl salicylates.

the zwitterionic antistatic agent may be one or more selected from quaternary ammonium inner salts, amphoteric alkylimidazolium salts, and alkyl amino acids.

as the nonionic antistatic agent, one or more selected from polyols, polyol esters, ethylene oxide adducts of alcohols or aminophenols, or ethylene oxide adducts of amines and amides may be used.

In a preferred embodiment, the antistatic agent is selected from one or more of antistatic agent T1502, antistatic agent Stadis450, antistatic agent Stadis 425.

in a more preferred embodiment, the antistatic agent is electrostatic agent T1502.

in a preferred embodiment, the weight ratio of the antistatic agent T1502 to the palm oil is (1.5-2): 1.

in a more preferred embodiment, the weight ratio of antistatic agent T1502 to palm oil is 1.7: 1.

In the present invention, the antistatic agent T1502 was purchased from Haian petrochemical plants of Jiangsu province.

In order to prevent the gasoline electrostatic fire accident, the antistatic agent T1502 is adopted to increase the conductivity of the gasoline, but the speed of the decay of the conductivity is easy to be too fast due to the fast movement speed of positive and negative ions of polysulfone and polyamine in the antistatic agent T1502. The inventor finds in research that when the weight ratio of the antistatic agent T1502 to the palm oil is (1.5-2): 1, the conductivity of the gasoline can be stabilized above 150pS/m, and the reason considered by the inventor is probably that the distance between positive and negative ions of polysulfone and polyamine is increased due to the long carbon chain, the multiple unsaturated double bonds and the multiple branched chains of the palm oil, the directional arrangement of the dipole ion pair formed by polysulfone and polyamine is inhibited, meanwhile, part of the palm oil reacts with polyamine, the dipole ion pair formed by part of polysulfone and polyamine is reduced, the movement speed of the positive and negative ions of polysulfone and polyamine is reduced to a certain extent, and the conductivity of the gasoline is further stabilized.

dynamic accelerator
