摘要： 利用全二维气相色谱，结合飞行时间质谱和火焰离子化检测器，对航天煤油组成进行了定性和定量分析，根据试验结果分析了族组成、碳数分布与航天煤油性能之间的关系。研究结果表明：该航天煤油主要由异构烷烃、单环环烷烃、双环环烷烃组成，具有高燃烧值和良好的稳定性。研究结果可以为航天煤油组成的分析和优化提供依据。

Abstract: Two-dimensional gas chromatography combined with time of flight mass spectrometry and flame ionization detector were applied for quantitive and qualitative analysis of rocket kerosene. The relationships between group-type, carbon-number distribution and capability of rocket kerosene were investigated based on the experimental data. The results show that the rocket kerosene mainly comprises isoparaffins, cycloalkanes, bicyclic alkanes. Special composition made for high combustion value and excellent stability. This research results can be used for the analysis and optimization of rocket kerosene components.

Key words: Kerosene, Gas chromatography, Carbon number
