Abstract

This article investigates the volatilization characteristics of binary and ternary fuel blends of cottonseed partially hydrogenated biodiesel, ethanol, and conventional diesel. The vapor pressure, enthalpy of evaporation, and activation energy of the fuel blends were obtained by thermogravimetric analysis and kinetic calculation. The physicochemical properties of the fuel blends showed that the ternary fuel blend of suitable mixing ratio had satisfactory cetane number, improved oxidation stability, and oxygen content with a significant decrease in the kinematic viscosity. In addition, the vapor pressure of the PHCME ternary fuel blends was increased by 18.4%, 17.2%, and 20.4% compared with PHCME binary fuel blends, and the enthalpies of evaporation of the ternary fuel blends increased slightly with different mixing ratios. The activation energy of PHCME ternary fuel blends was decreased by 3.5%, 6.8%, and 16.3% respectively, compared to the PHCME binary fuel blends. In conclusion, ethanol addition in the PHCME fuel blend improved the volatilization characteristics and the kinematic viscosity of the fuel blend without a significant adverse effect on the fuel properties of hydrogenated biodiesel.

部分加氢生物柴油-乙醇-柴油三元燃料混合物的挥发性能评估

本文研究了棉籽部分加氢生物柴油、乙醇和传统柴油的二元和三元混合燃料的挥发特性。通过热重分析和动力学计算获得了混合燃料的蒸气压、蒸发焓和活化能。混合燃料的理化性质表明，适当混合比的三元混合燃料具有令人满意的十六烷值、更高的氧化稳定性和含氧量，同时运动粘度显著降低。此外，与 PHCME 二元燃料混合物相比，PHCME 三元燃料混合物的蒸气压分别提高了 18.4%、17.2% 和 20.4%，三元燃料混合物的蒸发焓随不同的混合比略有增加。与 PHCME 二元燃料混合物相比，PHCME 三元燃料混合物的活化能分别降低了 3.5%、6.8% 和 16.3%。总之，在 PHCME 燃料混合物中添加乙醇可改善燃料混合物的挥发特性和运动粘度，而不会对加氢生物柴油的燃料特性产生明显的不利影响。
