Problems solved by technology

[0002] Microemulsified diesel oil has come out for decades, but it has not been popularized and applied so far. Its reason is that there are following deficiencies in the production method of microemulsified diesel oil in the prior art: 1. Poor stability and short shelf life: the microemulsified diesel oil developed by various countries in the world at present Most diesel oil is a white emulsion, the particle diameter of the water phase is 0.01-0.1mm, and the storage period is generally only 2-10 days. It cannot be used as commercial oil turnover, which brings limitations to popularization and use.
2. The cost of emulsifier is high: although it has a good fuel-saving effect, it does not save money, and the direct economic benefits for

Embodiment 1

[0024] Microemulsified diesel oil is prepared from 30.0% mineral diesel oil, 24.0% hog oil, 15.0% acidified oil, 25.0% methanol, 2.0% ammonia water, 0.8% ethylene glycol, 0.3% ethylenediamine, 2.0% triethanolamine and 0.9% butanol. The percentages are by weight.

[0025] Heat and melt hogwash oil and acidified oil respectively, add hogwash oil and acidified oil to mineral diesel oil according to the above weight ratio, add methanol, add ammonia water, ethylene glycol, ethylenediamine, triethanolamine and butanol or iso Pentanol is stirred and mixed to produce micro-emulsified biodiesel with a transparent appearance and can be stored for more than one year without stratification.

Embodiment 2

[0027] Microemulsified diesel oil is prepared from 40.0% mineral diesel oil, 20.0% hog oil, 15.0% acidified oil, 20.0% methanol, 1.8% ammonia water, 0.6% ethylene glycol, 0.4% ethylenediamine, 1.5% triethanolamine and 0.7% isoamyl alcohol , and its percentages are percentages by weight.

[0028] Heat and melt hogwash oil and acidified oil respectively, add hogwash oil and acidified oil to mineral diesel oil according to the above weight ratio, add methanol, add ammonia water, ethylene glycol, ethylenediamine, triethanolamine and butanol or iso Pentanol is stirred and mixed to produce micro-emulsified biodiesel with a transparent appearance and can be stored for more than one year without stratification.

Embodiment 3

[0030] Microemulsion diesel oil is prepared from 50.0% of mineral diesel oil, 20.0% of hogwash oil, 11.0% of acidified oil, 15.0% of methanol, 1.5% of ammonia water, 0.6% of ethylene glycol, 0.4% of ethylenediamine, 1.0% of triethanolamine and 0.5% of butanol. The percentages are by weight.

[0031] Heat and melt hogwash oil and acidified oil respectively, add hogwash oil and acidified oil to mineral diesel oil according to the above weight ratio, add methanol, add ammonia water, ethylene glycol, ethylenediamine, triethanolamine and butanol or iso Pentanol is stirred and mixed to produce micro-emulsified biodiesel with a transparent appearance and can be stored for more than one year without stratification.

Description

technical field [0001] The invention belongs to the field of biodiesel, in particular to a microemulsion biodiesel and a preparation method thereof. Background technique [0002] Microemulsified diesel oil has come out for decades, but it has not been popularized and applied so far. Its reason is that there are following deficiencies in the production method of microemulsified diesel oil in the prior art: 1. Poor stability and short shelf life: the microemulsified diesel oil developed by various countries in the world at present Most diesel oil is a white emulsion, the particle diameter of the water phase is 0.01-0.1mm, and the storage period is generally only 2-10 days. It cannot be used as commercial oil turnover, which brings limitations to popularization and use. 2. The cost of emulsifier is high: Although it has a good fuel-saving effect, it does not save money, and the direct economic benefits for users are not obvious. They mainly use Span series, Tween series and ol...
