This document specifies a method for the determination of total saturated hydrocarbons, total unsaturated hydrocarbons, total aromatics, total olefins concentration and detailed hydrocarbon types present in aviation turbine fuel with gas chromatography/mass spectrometry (GC-MS). This document is applicable to the aviation turbine fuels with a boiling range of 140°C to 300°C. The detailed hydrocarbon compositions include: paraffins, noncondensed cycloparaffins, condensed dicycloparaffins, condensed tricycloparaffins, monoolefins, cycloolefins, alkylbenzenes, indans and/or tetralins, CnH2n-10 (indenes, etc.), naphthalenes, CnH2n-14 (acenaphthenes, etc.), CnH2n-16 (acenaphthylenes, etc.) and tricyclic aromatics
The quality of aviation turbine fuel is directly related to the flight safety of aircraft. The performances and physical properties of aviation turbine are closely related to the hydrocarbon compositions. Therefore, the analysis of the hydrocarbon types is of great significance to the product quality control, performance properties improvement and improving the processing technology of aviation turbine fuel.
Compared with other existing methods, this method is more stable and less affected by reagents and materials, and avoiding to damage the operator's health caused by using of organic solvents and harmful light sources. In addition, the method is fast and efficient, which could provid the mass fraction of 13 hydrocarbons within 10 minutes. To sum up, this document provides a stable, safe and efficient analytical tool for hydrocarbon analysis.
