【摘要】：依兰油页岩有机质经过四氢萘逐级热溶解聚,热溶解聚物分别经过GC-MS检测并归纳分类,并结合热溶解聚残渣的FT-IR和~(13)C NMR分析结果,旨在从分子水平上揭示依兰油页岩有机分子结构特征。结果表明,依兰油页岩有机质经过200~400℃逐级热溶解聚后,200、300、350、375和400℃温度条件下逐级热溶解聚物的收率分别为8.8%、9.9%、18.5%、19.2%和23.4%,总收率达79.8%。在可溶性组分中,脂肪烃化合物占比为36.9%(其中直链烷烃27.4%,支链烷烃8.7%),酚/醇类占比为5.5%,芳香烃占比为32.0%,酮类占比为12.7%,醚/酯类占比为5.4%,其他化合物占比为7.5%。呈现脂肪烃芳烃化合物酮类酚/醇酯/醚的规律分布状态,其中27.4%直链烷烃中碳数分布在14~30并在C_(16)和C_(26)呈现两个峰值。
[Abstract]:The organic matter of Yilan oil shale has been thermally dissolved and polymerized by tetralin step by step, the thermal dissolved polymer has been detected and classified by GC-MS, and combined with the results of FT-IR and 13C NMR analysis of thermal dissolved accumulation residue.The aim of this paper is to reveal the organic molecular structure of Yilan oil shale at molecular level.The results showed that the yields of the organic matter of Yilan oil shale were 8.8and 18.519.2wt% and 23.4g respectively at the temperature of 20000350375 and 400 鈩，
