应用有自主权的天然羧酸盐及其改性产品为主要表面活性剂，通过表面活性剂相互作用参数βm测定，确定复配的非离子表面活性剂。然后测定复配表面活性剂∕水∕柴油拟三元相图。从中得到3种廉价高效的－10＃柴油微乳剂，其中包括少量的燃烧促进剂、十六烷值改进剂和消烟剂。经台架试验，平均节油率为20 %，NOx排放量下降20 %，每吨乳化柴油节省500元左右。

Using patented nature carboxylate and its modification as the major surfactant, we obtained compounded nonionic surfactant by the interaction parameter βm. Then we measured the pseudo ternary phase diagram of compounded surfactants/water/diesel oil, from which got three cheap and efficient diesel oil emulsifier. The emulsifier includes little flame accelerator,cetane improver and smoke suppressor. Through the bench test, we found that the average rate of economizing petrol was 20 % and the emissions of NOx dropped to 20 %. And every ton of emulsified diesel oil can save 500 yuan around.
