A New Emulsifier Behavior of the Preparation for Micro-emulsified Diesel Oil

Diesel oil emulsified with water can reduce diesel engine emissions, enhance fuel combustion efficiency, and save oil resources. However, the emulsions are not thermodynamically stable, which limits its commercial application. The micro-emulsion technique application improves stabilization of diesel-water system. The RW emulsifier was synthesized with oleic acid and amine, and methanol acts as co-emulsifier. The optimal composition of micro-emulsified diesel oil is 82% 0# diesel oil, 10% water, and 8% emulsifier and co-emulsifier, and the ratio of emulsifier and co-emulsifier is 5:1. The characterizations of the micro-emulsified diesel oil meet the commercial application. With the emulsifier dosage increasing, the stabilization of micro-emulsified diesel oil increased, and the co-emulsion enhanced the micro-emulsion stabilization.
