Abstract: In view of the problems of non-automation, long analysis time, complicated steps and poor precision in the determination of hydrocarbon composition of jet fuels, a rapid analysis technology for detailed hydrocarbon composition of jet fuel based on the combination of gas chromatography(GC) pre-separation and mass spectrometry(MS) was designed and implemented, and formed by the analysis method, analysis system and analysis platform composed of the whole process solution. The results of field application in an oil refinery showed that the results of detailed hydrocarbon composition analysis of jet fuel were in good agreement with those of existing standard methods. The results of the implemented technique scheme on different models of GC-MS were good consistency. The rapid analysis technique for detailed hydrocarbon composition of jet fuel could determine the content of 13 species of detailed hydrocarbons (including olefins) in jet fuel within 9 min, and the analysis process was automatic and green. The advantage of technical economic is remarkable.
