对茂名和抚顺油页岩的有机质及其超临界态甲苯抽出沥青,用各种分析方法进行比较,证明这两种油页岩有机质具有多聚物的结构特征。用显微光度计测定了有机质的平均反射率,由此计算得到折射率。应用Krevelen等关于煤的折射率一密度一元素分析一芳碳率一分子量的关联法,得到两种有机质平均结构单元重为4200—4800,并由此推算了它们的化学式为C_(302)H_(440)O_(23)N_6S_2与C_(312)H_(4(?))O_(16)N_7S_2。归纳了有关茂名油页岩有机质的结构特征,据此提出了它的平均结构单元的结构模型,并讨论了抚顺与茂名油页岩两者的异同。
The organic matter of Maoming and Fushun oil shale and its supercritical toluene were extracted by bitumen and analyzed by various analytical methods to prove that the organic matter of these two oil shale has the structural characteristics of polymer. The average reflectance of the organic matter was measured with a photometer, and the refractive index was calculated. Using the correlation method of Krevelen et al. On the refractive index-density-elemental analysis of coal and the aromatic carbon rate-molecular weight, the average weight of the two organic compounds is 4200-4800, and the chemical formula of the two organic compounds is C 302 H 2 (440) O_ (23) N_6S_2 and C_ (312) H_ (4 ()) O_ (16) N_7S_2. The structural characteristics of the organic matter in Maoming oil shale are summarized. The structural model of the average structural unit is proposed and the similarities and differences between the oil shale and the Fushun oilfield are discussed.
