本项研究主要是通过不同温度条件下的沥青质热解实验,研究热解温度对生物降解原油中生物标志物的恢复可能产生的影响。研究结果表明 340℃时,沥青质组分具有最大的产油率。另外,300℃之前,热解温度对沥青质热解产物中生物标志物的组成分布影响较小。因此,对于采用生物标志物恢复的方法来进行油/油对比时,300℃是沥青质热解实验较合适的温度。

In this study,pyrolysis experiments have been performed at different temperatures to onvestigate the possible effects of temperature on the recovery of the biomarkers from biodegraded oils.The results showed that the yield of the dichlormethane estracts is maximum at 340℃.In addition,pyrolysis temperatures lower than 300℃ have little effevt on the distribution of the biomarkers in the pyrolysates of asphaltenes.So 300℃ is a relatively suitable asphaltene pyrolysis temperature for oil/oil correlation.
