Abstract
The study compares the elemental composition of asphaltenes with the parameters of hydrocarbon biomarkers and Precambrian insoluble organic matter (OM) of the Aldan–Maya depression. The elemental composition of the asphaltenes was found to depend on the pyrolytic characteristics of the OM. Using asphaltene compositions in combination with biomarker parameters, the genetic and catagenetic features of difficult-to-study objects such as Precambrian bitumens can be characterized more accurately and reliably. The elemental composition of the asphaltenes was shown to correlate with the aromatic parameters that reflect the OM maturity. In contrast, the parameters of the asphaltenes show essentially no correlation with biomarker data for the saturated components.
摘要 该研究将沥青质的元素组成与阿尔丹-马亚凹陷的碳氢化合物生物标志物和前寒武纪不溶性有机物(OM)的参数进行了比较。研究发现,沥青质的元素组成取决于有机质的热解特征。将沥青质成分与生物标记参数相结合,可以更准确、更可靠地描述前寒武纪沥青质等难以研究对象的遗传和成因特征。研究表明,沥青质的元素组成与反映 OM 成熟度的芳烃参数相关。相反,沥青质的参数与饱和成分的生物标记数据基本没有关联。
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
