A new surrogate fuel of RP3 kerosene

摘要

摘要: 为了遴选出符合RP-3航空煤油物理与化学特性的模拟替代燃料，综合分析了RP-3航空煤油的物理与化学特性。针对其物理与化学特性，确定了RP-3航空煤油模拟替代燃料的遴选指标（包括摩尔质量、氢碳比、十六烷值与低热值）。针对遴选指标，提出了由正癸烷、正十二烷、异十六烷、甲基环己烷及甲苯等五种组分组成的RP3航空煤油模拟替代燃料，并对该模拟替代燃料中各组分的摩尔分数进行了优化。同时，对比分析了不同温度下该模拟替代燃料与RP3航空煤油的密度与运动黏度。结果表明，当该模拟替代燃料中正癸烷、正十二烷、异十六烷、甲基环己烷及甲苯的摩尔分数分别为14%、10%、30%、36%与10%时，该模拟替代燃料的摩尔质量、氢碳比、十六烷值与低热值与RP3航空煤油的相应数据非常吻合。同时，不同温度下该模拟替代燃料的密度与运动黏度变化趋势与RP-3航空煤油吻合较好。

Abstract: In order to select the surrogate fuel with the same physical and chemical properties as RP-3 kerosene, the physical and chemical properties of RP3 kerosene were analyzed. According to the physical and chemical properties of RP3 kerosene, the selection criterions of the RP3 kerosene surrogate fuel (including the molecular mass, hydrogencarbon ratio, cetane number and lower heating value) were determined. Based on the selection criterions, a fivecomponent RP-3 kerosene surrogate fuel comprising ndecane, n-dodecane, iso-cetane, methylcyclohexane and toluene was presented, and the mole fractions of these five components were optimized. Furthermore, the densities and kinematic viscosities of the surrogate fuel and RP3 kerosene were contrastively analyzed at different temperatures. The results show that the molecular mass, hydrogencarbon ratio, cetane number and lower heating value of the surrogate fuel, which comprise 14% ndecane/10% ndodecane/30% isocetane/36% methylcyclohexane/10% toluene (mole fraction), agree well with the corresponding criterions of RP3 kerosene. At the same time, the variation trends of the densities and kinematic viscosities of the surrogate fuel agree well with the corresponding experimental data of RP3 kerosene at different temperatures.
