摘　　要：近年未加氢催化热解技术被用于提取有机大分子中共价键结合的小分子化合物。本文利用固定床反应器对干酪根进行加氢催化热解,提取干酪根中共价键结合的生物标志化合物。实验条件:反应温度520℃,氢气压力大于10MPa,氢气流量8.0～10.0 L/min,催化剂Mo负载量达到1%。结果表明,加氢产物收率明显高于索氏抽提,产物的GC-MS分析与对应的索式抽提产物特征相似,而且含有更丰富的生物标志物,显示了更多的地球化学信息。In recent year, catalytical Hydropyrolysis is a newly developed technique used to set free small molecular from macromolecular of organic matters by covalented bond cracking. Fix-bed reactor was used to pyrolysis of kerogens to release the biomarker from kerogen by covalented bond cracking. The experiment condition is that the temperature is 520℃, hydrogen pressure is more than 10MPa, a constant hydrogen flow is between 8.0 and 10 L/min, the Mo loading is 1%. The experiments results revealed that the catalytic hydropyrolysis substantial improved the yield of extraction compared with the solvent extraction. From the analysis of GC-MS, the extraction via catalytic hydropyrolysis is similar to the solvent extraction, meanwhile, included more biomarkers and show more geochemistry information.
