摘要

. 页岩原位开采技术的应用需要一个合适的热解温度,才能通过干酪根热解获得最优质的油气产品。本研究对油页岩热解过程中不同热解温度下的油气产物进行气相色谱(GC)分析。结果表明:随着热解温度的升高,烃类气体含量先升高后降低;同时,非烃气体中h2含量逐渐增加,在550℃时达到64.07%。此外,当热解温度> 400℃时,页岩油中轻质组分的含量迅速增加。当热解温度超过500℃时,页岩油轻组分含量超过42%。最后,油页岩注入水蒸气热解得到的H含量比直接干馏得到的H含量高约8倍。水蒸气作用下的页岩油质量优于直接干馏。干酪根热解是在富h2环境下进行的,页岩油容易发生加氢反应。

Characteristics of oil and gas production of oil shale pyrolysis by water vapor injection
. An appropriate pyrolysis temperature is required to achieve the best-quality oil and gas products via kerogen pyrolysis for the application of the in situ shale exploitation technology. In this study, the oil and gas products obtained at different pyrolysis temperatures via the oil shale pyrolysis process were analyzed using gas chromatography (GC). The results show that as the pyrolysis temperature increases, the content of hydrocarbon gases first increases and then decreases. Meanwhile, the H 2 content in nonhydrocarbon gases gradually increases and reaches 64.07% at 550 °C. In addition, when the pyrolysis temperature is > 400 °C, the content of light components in shale oil rapidly increases. Further, when the pyrolysis temperature exceeds 500 °C, the content of light components in shale oil exceeds 42%. Finally, the H 2 content obtained from oil shale pyrolysis by injecting water vapor is approximately eight times higher than that obtained from direct dry distillation. Additionally, the shale oil quality under water vapor action is better than that under direct dry distillation. The kerogen pyrolysis is performed in the H 2 -rich environment and shale oil is prone to hydrogenation reaction.
