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%.
