چکیده انگلیسی
A method to determine n-paraffins, iso-paraffins, olefins-naphthenes and aromatics (PIO-NA) in kerosene samples by comprehensive two-dimensional gas chromatography coupled to time of flight mass spectrometry (GCÂ ÃÂ GC-TOFMS) is reported. This method is based on a correct identification of kerosene compounds by Scripting (Visual Basic programming) which establishes rules for filtering spectral data to locate compounds having defined spectral properties of a particular compound class. This tool implies a significant reduction of analysis time for very complex samples. Semiquantification of compound families is performed by adding the areas of the characteristic mass fragments of each compound class and their respective molecular ions. The kerosene samples for analysis were produced by different conversion processes such as catalytic reforming, alkylation, catalytic cracking and hydroprocessing depending on the kerosene distillation process. To assure the reliability of the method, samples were also analyzed by reference methods and good concordances were found between the results obtained.
