摘要: 结合近年来国内外含水柴油(包括乳化和微乳化)的研究现状,概述了含水柴油目前常用的乳化剂、在线乳化工艺、预乳化工艺过程和节能减排理论。有学者发现在含水柴油乳化剂配方中添加正构醇可以明显提高其乳化效果和稳定性;含水柴油的预乳化工艺主要包括机械搅拌、均质乳化、超声乳化和静电乳化等乳化工艺。含水柴油的节能减排理论还没有得到系统地完善,学者们提出了不同的观点,主要包括微爆理论、蒸发理论、共沸理论、水煤气效应和燃烧时间缩短等理论。在含水柴油发动机台架试验中,一些学者发现有发动机排放物中的氮氧化物(NOx)比普通柴油增加的现象,针对此现象,分析了出现这样情况可能的原因。最后提出含水柴油未来的研究方向和需要解决的问题。

Abstract: According to the present study of water-in-diesel fuel(including emulsification and micro-emulsification), this paper summarizes the current commonly used emulsifier, online emulsifying process, pre-emulsification process and the theory of energy conservation and emission reduction.Some scholars have found that the stability of the emulsion can be greatly improved by adding n-alkanol.The pre-emulsification technology includes mechanical stirring, homogeneous emulsification, ultrasonic emulsification, electrostatic emulsification and so on.The energy conservation and emission reduction theory mainly includes:micro-explosion theory, evaporation theory, co-boiling theory, water gas effect and reduction of burning time.In the test of diesel engine, some researchers have found that there is an increase of nitrogen oxide (NOx) of micro-emulsified diesel fuel.And, we analyze the possible reason.Finally, the future research direction and the problem required to be solved of the water-in-diesel are put forward.

Key words: water-in-diesel fuel, emulsifier, emulsification technology, energy conservation and emission reduction, nano-emulsion
