Embodiment 1

[0035] (1) Preparation of high-efficiency composite emulsifier (No. Y01)

[0036] Based on the total weight percentage of the high-efficiency composite emulsifier (Y01), uniformly mix 2% Tween 60 and 98% Span 80 to obtain the high-efficiency composite emulsifier Y01;

[0037] (2) Preparation of emulsion containing diesel oil, methanol and water

[0038] In non-plastic container, with the total weight percent of the emulsion that contains diesel oil, methyl alcohol and water, add the high-efficiency composite emulsifier (No. Y01) that 85% diesel oil and 2% above-mentioned steps (1) prepare, then frequency Put the 18KHZ-26KHZ ultrasonic probe under the liquid surface, after 1 minute of ultrasonic action, and ensure that the liquid temperature is lower than 80°C, add 5% methanol and 8% water one by one, and then apply ultrasonic wave for 3 minutes to form stable emulsion. The storage period of the emulsion is more than two months.

Embodiment 2

[0040] (1) Preparation of high-efficiency composite emulsifier (No. Y02)

[0041] Based on the total weight percentage of the high-efficiency composite emulsifier (No. Y02), uniformly mix 5% Tween 60 and 95% Span 80 to obtain No. Y02 high-efficiency composite emulsifier;

[0042] (2) Preparation of emulsion containing diesel oil, methanol and water

[0043] In non-plastic container, with the total weight percent of the emulsion that contains diesel oil, methyl alcohol and water, add the high-efficiency composite emulsifier (No. Y02) that the above-mentioned steps (1) of 70% are prepared, then frequency Put the 18KHZ-26KHZ ultrasonic probe under the liquid surface, after 1 minute of ultrasonic action, and ensure that the liquid temperature is lower than 80°C, add 8% methanol and 18% water one by one, and then apply ultrasonic wave for two to three minutes. A stable emulsion containing diesel, methanol and water can be formed. The storage period of the emulsion is more than th...

Embodiment 3

[0045] Preparation of Emulsion Containing Diesel Oil, Methanol and Water

[0046] In the non-plastic container, in the total weight percentage of the emulsion containing diesel oil, methyl alcohol and water, add the high-efficiency composite emulsifier (No. Y02) prepared by 80% diesel oil and 3% embodiment 2 step (1), then Put the ultrasonic probe with a frequency of 18KHZ-26KHZ under the liquid surface, after 1 minute of ultrasonic action, and ensure that the liquid temperature is lower than 80°C, add 5% methanol and 12% water one by one, and then apply ultrasonic wave for 2 minutes. A stable emulsion containing diesel, alcohol and water can be formed. The storage period of the emulsion is more than three months.

Abstract

The present invention relates to a liquid fuel and its preparation method, in particular, it relates to an emulsion liquid fuel containing diesel, alcohol and water and its preparation method. In a non-plastic container 60%-90% of diesel oil and 0.7%-0.8% of high-effective compound emulsifier are added, then the ultrasonic wave probe whose frequency is 18 KHz-26KHz is placed under the liquid surface, after 1 minute of ultrasonic wave action, progressively and successively 2%-11% of alcohol and 7.3%-21% of water are added, after 2-3 min. of ultrasonic water action, in the whole process the liquid temp. can not be over 80 deg.C, so that said invented emulsion liquor can be obtained. It can be used as fuel oil, and its performance is stable.

Description

technical field [0001] The invention relates to a liquid fuel and a preparation method thereof, in particular to a new emulsion liquid fuel containing diesel oil, alcohol and water and a preparation method thereof. Background technique [0002] Although petroleum is not a clean energy source, petroleum must be used as fuel or raw material for transportation, agriculture, industry, chemical industry and air transportation. Petroleum will still be one of the main energy sources in the 21st century. [0003] With the development of the national economy, urban motor vehicles are increasing. In the next few decades, petroleum will still be used as the main fuel for internal combustion engines and automobiles. Fuel emissions have become the main source of urban pollution. Exhaust emissions from motor vehicles and inefficient combustion of petroleum, suspended solids in the atmosphere, SO 2 And NOx concentration far exceeds the national standard to cause seri...
