The components in C 9 fraction of the pyrolysis gasoline were separated and identified by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-infrared spectroscopy (GC-IR). All analyses were performed on a 50 m capillary column coated with methylsilicone. An electron-impact ionization source (EI) was used in the experiments. The ionizing voltages of 70eV and 10eV were chose. A mercury cadmium telluride (MCT) was used as the detector of GC-IR. 52 components in C 9 fraction were identified The abundance of molecular ion peaks are increased remarkably with lowering down the ionization voltage, which benefits to measure molecular mass. Mass spectra can provide information of molecular mass and fragment ions of components and infrared spectroscopy has advantages over mass spectrometry on identifying isomers and functional groups. The simultaneous use of the two techniques can solve the problems caused by single technique of the both when analyzing the components in a complex mixture.

The constituents of C_9 fraction of pyrolysis gasoline were analyzed by gas chromatography(GC) with flame ionization detector(FID) and gas chromatography/mass spectrometry(GC/MS).A 100 m×0.25 mm i.d.×0.5 μm PONA column was used to improve the separation efficiency and sample load compared with the standard PONA column of 50 m ×0.20 mm i.d.Identifications of compounds were based on the standards of n-alkanes and a few aromatics,high accuracy retention time simulation and live retention time database,and cross-references with MS data.The search in live retention time database gives a few possible compounds that were co-eluting or adjacent from each other.While the MS search results for each peak always report 10 or even more compounds who has similar fragments.The cross-reference of the above method yields much more reliable identification results than normal GC/MS search.Quantitative analysis of each compound and the carbon number distribution were performed by GC with FID.Thirty-nine compounds with contents more than 0.2% in the C_9 fraction were identified.The relative standard deviation of quantitative analysis was below 5%.It provides a reliable method for detailed analysis of C_9 fraction.
