研究了不同甘油含量的甘油柴油混合燃料体系的热行为和氧化行为，以及相应的热解和燃烧动力学。热重分析表明，不同的燃料体系具有相似的热重曲线，这意味着它们的热降解和氧化降解相似。不同组成的燃料体系或添加表面活性剂鼠李糖脂和甘油，形成适量甘油的微乳液燃料和过量甘油形成乳状液，无一例外地导致柴油降解温度和分解速度的提高。然而，这些燃料系统的动力学性能是不同的。尽管不同甘油含量的GDH燃料具有相似的平均活化能，但在空气气氛中，高甘油含量的GDH燃料(乳化燃料)在高转化率下的活化能显著高于微乳液燃料(甘油含量低)。乳化GDH型燃料在发动机上使用时，可能会有较长的点火延迟，可能会导致燃烧不完全，进而导致较大的污染物排放。为了获得更好的发动机性能和排放特性，生产GDH燃料时应添加适量的甘油。
Thermal and oxidative behavior of glycerol-in-diesel hybrid (GDH) fuel systems with different contents of glycerol and their corresponding pyrolysis and combustion kinetics were studied. The thermogravimetric (TG) analysis indicates that different fuel systems had similar TG curves, which means their thermal and oxidative degradation similarities. The different compositions of the fuel systems or the addition of surfactant rhamnolipid and glycerol by forming microemulsion fuel with proper amount of glycerol and forming emulsion with excess glycerol, led diesel to an increasing degradation temperature and decomposition rate without exception. However, the kinetic performance of these fuel systems was different. Although GDH fuel with different contents of glycerol had comparable average activation energies, GDH fuel with high glycerol content (the emulsion fuel) had significantly higher activation energies at high conversion rate in air atmosphere than that of microemulsion fuel (with low glycerol content). Emulsion GDH fuel may have long ignition delay and can possibly result in incomplete combustion and further lead to heavier pollutant emissions when it is used in engines. GDH fuel should be produced with proper amount of glycerol addition in order to achieve better engine performances and emission characteristics.
