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
