对不同母质来源的沥青质进行了较详细的热解动力学研究,实验结果表明母质为Ⅰ型干酪根的沥青质其活化能分布范围宽,活化能在350kJ/mol以上时仍有较大量的生烃; Ⅱ型和Ⅲ型干酪根的沥青质其活化能分布范围相对较窄,活化能在350kJ/mol以上时分别只有少量烃生成和几乎无烃生成.针对具体母质来源的沥青质,热解动力学研究可以指示其成熟度状况.同时,结合对热解动力学参数频率因子的深入讨论,认为来自于Ⅰ型干酪根的沥青质具有高的再生油能力,而沥青质在油成气的潜力方面,则按照母质干酪根Ⅲ、Ⅱ和Ⅰ型的顺序依次降低.
The pyrolysis kinetics of asphaltene from different parent materials is studied in detail. The experimental results show that the asphaltene with type I kerogen has a wide distribution of activation energies. When the activation energy is above 350 kJ / mol, a large amount of Hydrocarbon generation. Asphaltene of type II and type III kerogen has a relatively narrow distribution of activation energy, with only a small amount of hydrocarbon generation and almost no hydrocarbon generation, respectively, when the activation energy is above 350 kJ / mol. Asphaltene from specific parent materials, pyrolytic kinetic studies can indicate its maturity status. In the meantime, considering the frequency factor of the kinetic parameters of pyrolysis, the asphaltene derived from type I kerogen is considered to have a high ability to regenerate oil. Asphaltene, in terms of the potential of oil gas, The order of Ⅱ and Ⅰ decreased in turn.
