Problems solved by technology

In the prior art, there are emulsifiers compounded by Span 80 and Tween 80, or emulsifiers compounded by Span 80 and Tween 20, or polyethylene glycol octylphenyl ether (abbreviated as Op) and The emulsifier compounded with ethanol, although the first two can achieve the emulsification effect and also have the characteristics of good stability, but the viscosity of the emulsified diesel oil is relatively large, and the amount of emulsifier is also large, which is difficult to adapt to industrial production. Op and ethanol compound What the emulsifier obtains is white emulsion, and viscosity performance is also very poor, and its performance comparison can refer to table 1
To sum up, the existing diesel emulsification technology still generally has the technical problems that the stability, viscosity and emulsification cost cannot be taken into account. Today, with the increasing demand for diesel oil, a new type of emulsified diesel oil with ideal comprehensive technical indicators is yet to be launched.

Abstract

The invention provides an engine diesel oil emulsifying agent and engine emulsified diesel oil. The engine diesel oil emulsifying agent is prepared by mixing sodium oleate saturated solution, OP-ethanol and nonyl phenol polyethylene glycol (4) ether NP-4 in a volume ratio of 2:5:(8-12), wherein the OP-ethanol is prepared by mixing polyglycol octyl phenyl ether and ethanol in the same volume ratio. The engine diesel oil emulsifying agent is mixed with water-containing diesel oil in a volume ratio of 1:500, wherein the water content of the diesel oil is 9 to 10 percent of the volume of the diesel oil, and the mixture is emulsified at the temperature of between 40 DEG C and 55 DEG C to prepare the engine emulsified diesel oil. The engine diesel oil emulsifying agent and the engine emulsified diesel oil of the technical scheme have the technical advantages of viscosity and density close to those of purified diesel oil, high transparence, stability and no demixing; besides, the emulsification amount is low, and the emulsification cost is low.

Description

technical field [0001] The invention relates to a production method of an engine diesel emulsifier and an engine emulsified diesel. Background technique [0002] As the heart of automobiles, diesel engines have become a development direction of the automobile industry, followed by technical research on diesel energy saving, high combustion efficiency and emission reduction. Existing theoretical studies have shown that a certain amount of water and surfactants are mixed into diesel oil, and a new type of fuel, emulsified diesel oil, can be made through the emulsification process, which can make the combustion faster and more complete, and has energy-saving and low-emission technologies. Effect. However, as we all know, emulsion is a thermodynamically unstable system, and there is a tendency of demulsification and stratification during storage. Therefore, stability is an important technical index for emulsified diesel oil. Therefore, the selection and preparation of surfactan...
