| 1 | A GC×GC-ToFMS Investigation of the Unresolved Complex Mixture and Associated Biomarkers in Biodegraded Petroleum显示文摘Heavy biodegraded crude oils have larger numbers of coeluting compounds than nonbiodegraded oils, and they are typically not resolved with conventional gas chromatography(GC). This unresolved complex mixture(UCM) has been investigated using comprehensive two-dimensional gas chromatography–time-of-flight mass spectrometry(GC×GC-To FMS) within a set of biodegraded petroleums derived from distinct sedimentary basins, including northwestern Sichuan(Neoproterozoic, marine), Tarim(Early Paleozoic, marine), Bohai Bay(Eocene, saline/brackish) and Pearl River Mouth(Eocene, freshwater). In general, the hydrocarbons that constitute the UCM in petroleum saturate fractions can be classified into three catalogues based on the distributions of resolved compounds on two dimensional chromatograms. Group 1 is composed mainly of normal and branched alkanes, isoprenoid alkanes and monocyclic alkanes; Group 2 comprises primarily terpanes ranging from two to five rings, and Group 3 is dominated by monoaromatic hydrocarbons such as tetralins and monoaromatic steranes. In addition, the UCM is source dependent and varies between oil populations. i.e., the UCM of petroleum derived from Precambrian and Early Paleozoic marine, Eocene saline/brackish and freshwater source rocks is specifically rich in higher homologues of A-norsteranes, series of 1,1,3-trimethyl-2-alkylcyclohexanes(carotenoid-derived alkanes), and tetralin and indane compounds, respectively. | WANG Guangli Bernd Rolf Tatsuo SIMONEIT SHI Shengbao WANG Tieguan ZHONG Ningning WANG Peirong | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 3 |
