【 摘 要 】

The goal of thisarticle is to discuss the application of comprehensive two-dimensional gas chromatography(GCxGC) to petrochemical samples. The use of GCxGC for petroleum and petroleumderivatives characterization, through group type analysis, or BTEX (benzene,toluene, ethylbenzene, xylenes), total aromatic hydrocarbons, polyaromatic hydrocarbons,sulfur-containing, oxygen-containing, and nitrogen-containing compounds is presented.The capability of GCxGC to provide additional specific chemical informationregarding petroleum processing steps, such as dehydrogenation of linear alkanes,the Fischer-Tropsch process, hydrogenation and oligomerization is also described.In addition, GCxGC analyses of petrochemical biomarkers and environmental pollutantsderived from petrochemicals are reported.
