摘要: Abstract Catalytic hydropyrolysis (HyPy) was used to release covalently bound aromatic hydrocarbons from both mature and overmature Permian source rocks in the Sichuan Basin, China. The released were discussed compared with their free counterparts obtained by Soxhlet extraction. Furthermore, a Dalong kerogen selected for artificial simulation experiments. HyPy experiments of above thermal altered kerogens subsequently conducted. results sequence also those natural maturity sequence. For sequence, distributions methylphenanthrenes methyldibenzothiophenes are quite similar at different stages. Triaromatic monoaromatic steroids which aromatization products not detected aromatics all samples. indicate that rearrangement methyl group on nucleus within retarded some extent or even prohibited, due protection macromolecular structure below vitrinite reflectance 2.4%. It implies maturity-related biomarker parameters based reactions probably appropriate assessment. Meanwhile, perylene is easily alteration still existent Formation over stage (Ro: 1.8%) until temperature 400 °C (H/C: 0.49). means can be protected destruction stress least Ro 1.8% (or H/C > 0.5). permitted geochemical characterization rocks.
