摘要: 利用催化加氢热解技术提取了高演化沉积有机质中共价键结合的生物标志化合物,探讨了干酪根催化加氢热解反应机理,并考察了反应产物分布和影响反应的关键变量.实验表明,程序升温固定床催化加氢热解反应条件:温度上限为520℃,升温速率为5℃/min,氢压大于10MPa,氢气流量为5L/min,分散型催化剂为MoS2(Mo的质量分数为1%).实验结果表明,催化加氢热解对提取高产率、结构重排少的干酪根中共价键结合的生物标志化合物有独特作用,该方法可以应用于有机地球化学领域.

Abstract: The catalytic hydropyrolysis technology was used to release the covalently bound biomarkers from the high-evolution sedimentary organic matter.The reaction mechanism of catalytic hydropyrolysis of kerogen was analyzed.The product distribution and the effects of key variables on the reaction were investigated.The conditions of temperature-programmed reduction from kerogen with catalytic hydropyrolysis technology in fixed-bed were obtained.The upper limit of temperature is 520℃,the heating rate is 5℃/min,the flow rate of hydrogen is 5L/min,the hydrogen pressure is over 10MPa,and the mass fraction of dispersed sulphided molybdenum is 1%.The experiment results show that the catalytic hydropyrolysis technology can be successively applied to study the high-evolution sedimentary organic matter.

Key words: catalytic hydropyrolysis technology, high-evolution sedimentary organic matter, kerogen, covalently bond, biomarker, reaction mechanism
