世界若干地区油页岩费歇尔热解生成油的比较

本文研究了油页岩经费歇尔(Fischer)热解得到的生成油,用以比较产于世界几大洲、不同沉积的12种油页岩。采用分离技术将热解生成油按化合物类型分开,分出的馏份用气相色谱鉴定。另外还比较了油页岩和页岩油的元素组成以及页岩样品的固体~(13)C核磁共振波谱。结果表明,第三纪、湖相沉积油页岩热解后,生成含有大量从低碳数到高碳数正构烷烃的石蜡基页岩油;而地质年代相对古老的海相油页岩,却生成只含低碳数烷烃的芳香基页岩油:

COMPARISON OF FISCHER ASSAY SHALE OILS PRODUCED FROM DIFFERENT OII、SHALES

Twelve oil shales from various deposits throughout the world were compared by studying the chemical composition of their Fischer assay- produced oils. Two Chinese oil shales, four United States, oil shales, two Australian oil shales, two Israeli oil shales, one Turkish oil shale, and one moroccan oil shale were Fischer assayed to produce shale oils that were then characterized by separation techniques. The oil shales ranged in geologic age from Devonian to Tertiary and represented widely different depositional environments and precursor source materials. Fis- cher assay oils were fractionated into different compound types before charac terization. The isolated fractions were characterized by gas chro- matography. In addition, elemental analyses of all shale oils and solid- state carbon-13 nuclear magnetic resonance spectra of the raw shales were obtained for comparison with other results. The Chinese, Green River, Australian and Turkish oil shales, which were of Tertiary age and lacustrine environment, produced moere aliphatic shale oils containing larger amounts of both low and high carbon number alkanes. On the contrary, the other six older oil shales, which were of marine sediments, produced more aromatic shale oils containing lower carbon number alkanes.
