Production of n-alkanes and polycyclic aromatic hydrocarbons in coal pyrolysis

摘要

Pyrolysis in combination with gas chromatographic separation and mass spectrometry detection is a useful tecnique for following the compounds which are produced in coal pyrolysis. Two families of compounds, linear hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) were followed with a single-ion monitoried program in order to enhance the detection limit of the method. A complete study of these two families of compounds and the pyrolysis temperature was carried out. Some conclusions were obtained about production at different temperatures by making comparisons between the experiments.
