近年来,煤成油研究在诸多方面取得了可喜进展.煤在地质地球化学演化过程中的化学反应及其与煤成油形成演化的关系的研究,是煤成油形成机理研究中的关键问题之一,本文将简要论述煤液态烃生成演化的重要规律之一——低成熟阶段煤可溶有机质的热缩聚作用.
In recent years, research on coal-to-oil has made great progress in many aspects.The research on the chemical reaction of coal in geological geochemical evolution and its relationship with the formation and evolution of coal is the key issue in the study of the formation mechanism of coal into oil In this paper, one of the important laws governing the formation and evolution of coal-liquid hydrocarbons is briefly discussed. The thermal-polycondensation of coal-soluble organic matter in the low-maturity stage will be briefly discussed.
