preparation example Construction

[0029] A preparation method of alcohol-based fuel, comprising the steps of:

[0030]According to the number of parts by mass, take 60~90 parts of methanol, 2~5 parts of ethanol, 3~6 parts of catalytic active agent, 1~3 parts of antiknock additive, 2~5 parts of oxygen-containing blending agent, 8~15 parts of petroleum ether 1~3 parts of 2-methoxyethyl acetate were stirred and mixed for 3~5 hours, and left to stand for 10~12 hours to obtain alcohol-based fuel.

Embodiment 1

[0032] Catalytic active agent: (1) Take AEO-3 and add n-octane at a mass ratio of 1:6, stir and mix for 20 minutes to obtain a mixture, take cerous nitrate and add methanol and formamide at a mass ratio of 2:6:3, and then add nitric acid 40% of the cerium mass fraction is 20% sodium hydroxide solution, stirred and mixed for 30 minutes to obtain mixture a;

[0033] (2) Take the mixture and add it dropwise to mixture a according to the mass ratio of 3:2, control the dropping time for 30 minutes, introduce oxygen, stir and mix at 20°C for 54 hours to obtain a stirred mixture, take the stirred mixture and add acetone according to the mass ratio of 10:3 , Let stand for 3h, centrifuge, take the precipitate, wash with methanol, and dry to obtain the catalytic active agent.

[0034] Anti-knock additive: take o-cresol and add diethylenetriamine at a mass ratio of 1:3, pass through nitrogen protection, heat up to 60°C and stir and mix for 50 minutes, then add dropwise 80% of the mass fr...

Embodiment 2

[0040] Catalytic active agent: (1) Take AEO-3 and add n-octane at a mass ratio of 2:7, stir and mix for 25 minutes to obtain a mixture, take cerous nitrate and add methanol and formamide at a mass ratio of 3:7:5, and then add nitric acid 45% of the cerium mass fraction is 20% sodium hydroxide solution, stirred and mixed for 35min to obtain mixture a;

[0041] (2) Take the mixture and add it dropwise to mixture a according to the mass ratio of 6:4, control the dropping time for 35 minutes, feed oxygen, stir and mix at 23°C for 60 hours to obtain a stirred mixture, take the stirred mixture and add acetone according to the mass ratio of 13:5 , Let it stand for 4h, centrifuge, take the precipitate, wash it with methanol, and dry it to obtain the catalytic active agent.

[0042] Anti-knock additive: take o-cresol and add diethylenetriamine at a mass ratio of 2:5, pass through nitrogen protection, heat up to 70°C and stir and mix for 55 minutes, then add dropwise diethylenetriamine ...

Abstract

The invention discloses an alcohol-based fuel and a preparation method therefor and belongs to the technical field of fuels. According to the method, a catalysis activator with homogeneous-dispersed nanoparticles is formed through dissolving AEO-3 in n-octane, then, adding methanol and formamide to form a microemulsion and then adding cerous nitrate nanoparticles, and thus, pollutants discharged from combustion are reduced; an antiknock additive is synthesized by a Mannich reaction through providing phenyl by o-methylphenol and providing hydroxyl, amino, formaldehyde base and the like by diethylenetriamine, and thus, the stability and safety of combustion of the alcohol-based fuel are improved; and the intersolubility among all ingredients of the alcohol-based fuel is promoted through adding petroleum ether, so that the activator can plays a full role during the combustion of the fuel, the activation energy of C-H bonds of fuel molecules are lowered, and the quantity of activated molecules is greatly increased. According to the alcohol-based fuel and the preparation method therefor, the problems of the current alcohol-based fuels that the combustion is insufficient and a large number of hazardous and noxious substances are generated after combustion are solved.

Description

technical field [0001] The invention belongs to the field of fuel technology, and in particular relates to an alcohol-based fuel and a preparation method thereof. Background technique [0002] Petroleum is a non-renewable resource. The excessive development and use of it has caused the current energy crisis, especially the use of vehicle fuel, and has also caused serious environmental pollution. If calculated at the current consumption rate, in Oil resources will be exhausted in the near future. Under the current grim situation, alcohol-based fuel, as a resource to replace diesel oil and liquefied petroleum gas, is used in industrial oil-fired boilers, boilers in the catering industry, and stoves, which can effectively reduce the use of oil and reduce environmental impact. Pollution, lower fuel usage costs, etc. Alcohol-based fuel is not only a fuel mainly composed of alcohols (such as methanol, ethanol, butanol, etc.), but also a cheap, clean fuel next to hydrogen, which ...
