Abstract

A rapid analysis method for determination of hydrocarbon types in aviation turbine fuel was investigated in this study. A kind of reversible adsorption material packed as an unsaturated trap was used to separate saturated hydrocarbons and unsaturated hydrocarbons in the GC-MS system. No manual process or organic reagent was needed during the entire analysis process. The contents of 13 kinds of hydrocarbons, including paraffins, monocycloparaffins, dicycloparaffins, tricycloparaffins, monoolefins, cycloolefins, alkylbenzenes, C_nH_2n-8 aromatics, C_nH_2n-10 aromatics, naphthalenes, C_nH_2n-14 aromatics, C_nH_2n-16 aromatics, and C_nH_2n-18 aromatics were calculated by the characteristic mass fragments detected by MS with the modified matrices of ASTM D2425. The overall analysis time was less than 10 min. The precision of this test method has been conducted with 8 laboratories attended and 16 samples analyzed. The performance of this new method was demonstrated by comparing the results tested by ASTM D1319, ASTM D2425, and ASTM D6379. This rapid analysis method can provide hydrocarbon compositions of aviation turbine fuels or other liquid hydrocarbon samples within the same distillation range.

利用气相色谱-质谱法测定航空涡轮机燃料中碳氢化合物类型的快速分析方法。

本研究探讨了一种测定航空涡轮燃料中碳氢化合物类型的快速分析方法。在气相色谱-质谱系统中，使用一种可逆吸附材料作为不饱和捕集器，将饱和碳氢化合物和不饱和碳氢化合物分离开来。整个分析过程无需人工操作和有机试剂。萘、CnH2n-14 芳烃、CnH2n-16 芳烃和 CnH2n-18 芳烃的分析结果是根据 MS 检测到的特征质量片段计算得出的，采用的是 ASTM D2425 的改进基质。整个分析时间不到 10 分钟。有 8 个实验室参加了该测试方法的精密度测试，分析了 16 个样品。通过比较 ASTM D1319、ASTM D2425 和 ASTM D6379 的测试结果，证明了这种新方法的性能。这种快速分析方法可提供相同馏程范围内航空涡轮燃料或其他液态碳氢化合物样品的碳氢化合物成分。
