甲醇汽油的稳定性能研究

Stability Study of Methanol-gasoline Blend

分析了甲醇汽油的抗爆性、热值、互溶性等基本特性及温度、汽油组分、水分含量等因素对其稳定性的影响.温度越高、芳烃含量高,互溶性越好;微量水分会提高甲醇汽油的临界互溶温度,降低稳定性.讨论了甲醇汽油助溶剂的助溶机理,选择既能与水或甲醇相互作用又与汽油性质相似的助溶剂,能改善甲醇汽油的稳定性能;介绍了数学模型在甲醇汽油实验研究过程中的重要性.

This paper analyzed the basic characteristics of methanol- gasoline blend, such as anti- knock property, caloric value, inter-solubility, as well as such factors＇ effect as temperature, gasoline composition and water content. Higher temperature and high content of aroma could result in better inter - solubility. Little water could increase its inter - solubility temperature and decrease its stability. The solvent mechanism of the methanol - gasoline co - solvent was also discussed. The co- solvent could act on methanol or water and had similar characteristic with gasoline. This paper further introduced the importance of the mathematics model in the process of experiment studying of methanol- gasoline blend.
