specific Embodiment approach 1
[0026] Specific embodiment one: the preparation method of the composite additive of the emulsified diesel oil of high combustion efficiency described in the present embodiment is carried out according to the following steps:
[0027] Step a, take by weight respectively the sodium hydroxide that is 0.5 parts by weight, the rosin that 8 parts by weight are kerosene and the rosin that are 0.5 parts by weight, put the weighed sodium hydroxide, kerosene and rosin in the container Dissolve in the state of heating to 80-90°C, and stir evenly with a magnetic stirrer to obtain A solution, and lower the temperature to 40-50°C for use;
[0028] According to parts by weight, take respectively Tween 60 with 25 parts by weight, Tween 20 with 25 parts by weight, Span 80 with 30 parts by weight, sodium petroleum sulfonate with 10 parts by weight, Potassium permanganate with a count of 1, put the weighed Tween 60, Tween 20, Span 80, sodium petroleum sulfonate, and potassium permanganate in a c...
specific Embodiment approach 2
[0037] Specific embodiment two: the preparation method of the emulsified diesel oil of high combustion efficiency described in the present embodiment is carried out according to the following steps:
[0038] Step 1, prepare composite additive;
[0039] Step 2, weighing 77 to 92 parts of heavy oil, 5 to 20 parts of water, and 3 parts of composite additives as raw materials in parts by weight;
[0040] Step 3, pour the heavy oil weighed in step 2 into the reaction vessel, heat and keep the temperature at 30°C for standby;
[0041] Step 4. Add the compound additives and water weighed in step 2 into the reaction vessel of step 3 in turn, pre-mix with a magnetic stirrer, and then stir with an overhead stirrer. The stirring speed is 1200rpm, the stirring time is 20min, and the stirring temperature 30°C.
[0042] The calorific value of the emulsified diesel oil prepared under the same additive amount of 3.0 parts by weight and different water content of 5 to 20 parts by weight obtain...
specific Embodiment approach 3
[0043] Specific embodiment three: the preparation method of the emulsified diesel oil of high combustion efficiency described in the present embodiment is carried out according to the following steps:
[0044] Step 1, prepare composite additive;
[0045] Step 2, taking by weight respectively 88.5 parts of heavy oil, 10 parts of water, and 1.5 parts of composite additives as raw materials;
[0046] Step 3. Pour the heavy oil weighed in step 2 into the reaction vessel, heat and keep the temperature at 30°C for later use;
[0047] Step 4. Add the compound additives and water weighed in step 2 into the reaction vessel of step 3 in sequence, and after pre-mixing with a magnetic stirrer, stir with an overhead stirrer, the stirring speed is 1200rpm, the stirring time is 40min, and the stirring temperature 30°C.
[0048] The measured calorific value of the emulsified diesel oil with high combustion efficiency obtained in this embodiment is 42.02MJ / kg, the theoretical calorific value...
