Preparation And Influencing Factors Of Explosion Proof Diesel Oil

Explosion proof diesel is studied due to its ability to reduce the possibility of explosion. It has high fire resistance and stability. As a fuel, the combustion performance of explosion proof diesel close to ordinary diesel. If the tank with explosion proof diesel hit by artillery shells, it couldn't explode for second and greatly reduce casualties. The main issue of explosion proof diesel is the microemulsion technology. Microemulsified diesel fuel generally include diesel surfactants, cosurfactant and water. In this study, the effect of surfactant, cosurfactant and water on microemulsified diesel was discussed. Details are as follows.1. Anionic surfactant and non-ionic surfactant were used in this experiment to form microemulsified diesel. It was found that the lipopholic group and counterion had different influence to the formation of microeulsion. oleic acid monoethanolamine, compared another lipophilic group, has more efficient. The more polyoxyethylene group, the stronger hydrophilic. It was easy to absorbe lipophilic alcohol and has the maximum water content. Anionic surfactant systems had more water and alcohol content in microemulsions. Non-ionic surfactants tended to absorb hydrophilic cosurfactant2. Alcohol with carbon chain length between one to eight were used to investigate the effect of cosurfactant on microemulsion systems. And the maximum water content of microemulsified diesel and their physical and chemical properties were discussed. The results showed that alcohol with appropriate carbon chain length can form microemulsion. With the increase of cosurfactant carbon chain length, the water content of oleic acid monoethanolamine system, Span-80/ATX-100 system and Span-80/ATX-114 system increased first and then decreased. The longer cosurfactant carbon chain length, the less water content in naphthenic acid system. Microemulsified diesel with different alcohols has different physical and chemical properties. N-decanol compared to terpineol, has less alcohol content, more water content. With the alcohol content increased, pour point and viscosity remained unchanged. Flash point declined and stability increased.3. Microemulsified diesel with different water content was prepared and their physical and chemical properties and explosion proof properties were characterized. The results showed that there is little effect of water content on flash point and pour point in microemulsified diesel. Particle size and viscosity increased with the water content increasing. When the water content more than 15%, the explosion time of microemulsified diesel delayed.
