Characteristics of the Composition of Saturated Hydrocarbon Biomarker Compounds in the Aqueous Thermal Degradation Products of Pinus Sylvestris Leaves and Their Indicative Significance
Based on the hydrothermal simulation experiments of water pine addition,the main products of water pine pyrolysis,such as n-alkanes,isoprenoids and steroidal alkanes,were investigated.The experimental results show that with the increase of simulation temperature,the content of n-alkanes in the pyrolysis products gradually increases,the main peak carbon gradually moves forward from the initial n-C27,the ratio of Pr/n-C17and Ph/n-Ci8 increased,and the distribution form of regular steroidal alkanes is transformed from the"V"type to the anti-"L"type.After reaching 340 ℃ all kinds of compounds are unstable and thermally cleaved,and a variety of parameters are changed.By exploring the evolution law of biomarker compounds in the process of organic matter maturation,a basic understanding for the study of hydrocarbon generation mechanism in terrestrial organic matter is provided.
