Embodiment 1

[0025] Add 10 parts of ethylene glycol dinitrate, 15 parts of glycerin trinitrate, 10 parts of heptyl nitrate, 10 parts of diphenylamine, 1 part of succinimide and 2 parts of p-phenylenediamine into the raw material mixing tank, stir After fully mixing and standing for 20 to 40 minutes, add 10 parts of ethylene glycol methyl ether, 16 parts of barium thiosulfate, 2 parts of naphthalene and 3 parts of camphor, stir for 15 to 30 minutes, and then add dodecene Add 2 parts of methyl succinic acid, 3 parts of cetyl dimethyl ammonium chloride, 1 part of cetyl phenol, and 1 part of polyoxyethylene cetyl phenol ether, stir well, and let stand for 20 The diesel multi-effect composite additive of the present invention can be obtained in ~30 minutes.

[0026] Adding the obtained product into diesel oil at a ratio of 200ppm can increase the cetane number of diesel oil by 8 units, reduce the emission of CH by 30%, and increase the fuel saving rate by 2.0%.

Embodiment 2

[0028] Add 12 parts of ethylene glycol dinitrate, 12 parts of glycerin trinitrate, 10 parts of heptyl nitrate, 12 parts of diphenylamine, 2 parts of succinimide and 3 parts of p-phenylenediamine into the raw material mixing tank, stir After fully mixing and standing for 20 to 40 minutes, add 16 parts of ethylene glycol methyl ether, 20 parts of barium thiosulfate, 3 parts of naphthalene and 3 parts of camphor, stir for 15 to 30 minutes, and then add dodecene Add 5 parts of methyl succinic acid, 5 parts of cetyl dimethyl ammonium chloride, 3 parts of cetyl phenol, and 1 part of polyoxyethylene cetyl phenol ether, stir well, and let stand for 20 The diesel multi-effect composite additive of the present invention can be obtained in ~30 minutes.

[0029] The obtained product is added into diesel oil according to the proportion of 600ppm, which can increase the cetane number of diesel oil by 10 units, reduce the emission of CH by 32%, and increase the fuel saving rate by 3.0%.

Embodiment 3

[0031] Add 15 parts of ethylene glycol dinitrate, 20 parts of glycerin trinitrate, 16 parts of heptyl nitrate, 16 parts of diphenylamine, 5 parts of succinimide and 5 parts of p-phenylenediamine into the raw material mixing tank, stir After fully mixing and standing for 20 to 40 minutes, add 25 parts of ethylene glycol methyl ether, 28 parts of barium thiosulfate, 5 parts of naphthalene and 3 parts of camphor, stir for 15 to 30 minutes, and then add dodecene Add 8 parts of cetyl succinic acid, 6 parts of cetyl dimethyl ammonium chloride, 1 part of cetyl phenol, and 3 parts of polyoxyethylene cetyl phenol ether, stir well, and let stand for 20 The diesel multi-effect composite additive of the present invention can be obtained in ~30 minutes.

[0032] When the obtained product is added to diesel at a ratio of 1000ppm, the cetane number of diesel can be increased by 15 units, the emission of CH can be reduced by 45%, and the fuel saving rate can be increased by 4.2%.

Abstract

The invention discloses a multiple-effect composite additive of diesel oil, comprising the following raw materials in parts by weight: 10-15 parts of glycol dinitrate, 12-20 parts of glycerol trinitrate, 8-16 parts of heptyl ester nitrate, 9-18 parts of diphenylamine, 1-6 parts of succinimide, 1-6 parts of p-phenylenediamine, 10-28 parts of ethylene glycol methyl ether, 16-29 parts of barium thiosulfate, 2-5 parts of naphthalin, 2-5 parts of camphor, 2-8 parts of dodecencylsuccinic acid, 2-8 parts of hexadecyl dimethyl ammonium chloride, 1-3 parts of hexadecyl phenol and 1-3 parts of polyoxyethylene hexadecyl phenol ether. The invention also discloses a preparation method of the composite additive. The composite additive can greatly enhance the combustion performance of the diesel oil and reduce the discharge amount of harmful substances, i.e. CO and hydrocarbon (CH), contained in tail gas and also has certain oil saving effect.

Description

technical field [0001] The invention relates to a diesel oil additive, in particular to a diesel oil multi-effect compound additive and a preparation method thereof. Background technique [0002] With the wide application of diesel engines, the consumption of diesel is increasing year by year. However, a large amount of diesel consumption will inevitably lead to further aggravation of harmful emissions from vehicles. Due to the serious impact of emissions on the ecological environment, human health and economic development, governments of various countries have successively formulated strict emission regulations to limit the harmful emissions of diesel vehicles. Therefore, further reducing the fuel consumption and pollution of diesel vehicles is an urgent problem to be solved at present. Among the many solutions, the use of diesel additives is not [0003] In order to improve the quality of diesel and promote combustion, a very small amount of some chemical substances are...
