摘要
本文对黄县褐煤、茂名油页岩进行了热模拟实验。根据对模拟实验的产物分析,取得了一些认识:①排出烃的nC_(21)^-/nC_22^+比残留烃要高。甾萜烷,尤其是C_(27)/C_(29)甾及C_(29)萜烷、C_(30)萜烷的βα/αβ值具有较大的差异。相对于其他多环芳烃,低分子量的萘系列、联苯系列、芴系列被优先排出。重质芳烃组分如芘、(艹屈)系列、荧蒽系列则难于运移;②通过对不同温阶残留烃与排出烃的纵向对比研究,发现随排烃量的增加,它们之间的差别变小。
Based on a series of thermal simulating experiments carried out for the Huangxian lignites and the Maoming oil shales and their products data analysis, some knowledge is concluded in this paper:1) The nC_(21)^-/nC_(22)^+ ratio of the expulsive hydrocarbon is higher than that of the residual hydrocarbon. The βα/αβ ratio for sterane, terpane differ greetly, especialy for C_(27) sterane/C_(29) sterane and C_(29) terpane, C_(30) terpane. Expulsion of naphthalenes, dighenyles, fluorenes with low molecular weight is in preference to that of other polycyclicaromatics. Heavier aromatics such as pyrenes, chrysenes and fluoranthenes are difficult to migrate.2) Comparison between the remaining hydrocarbon and the expulsive hydrocarbon during different temprature stages shows that their differences decrease with the increasing expulsion of the hydroearbon.
