页岩油组成的研究——Ⅰ.抚顺、茂名页岩油的分离

RESEARCH ON SHALE OIL COMPOSITION Ⅰ. SEPARATION OF SHALE OIL FROM FUSHUN AND MAOMING

氧化铝在不同的温度(1120、1035、970、300℃)下焙烧,可以得到活性各不相同的吸附剂。应用减活氧化铝柱色谱法对抚顺、茂名页岩油进行分离,可将油中极性相同或相近的组分富集在同一馏分中,且其损失率较小。

Chinese shale oils from Fushun and Maoming were fractionated into sub-groups of chemical compounds by four chromatographic columns in series, in which the adsorbent alumina was thermally deactivated at different temperatures. The shale oils were separated into different fractions on the basis of polarity by elution using solvents of increasing polarity. No preliminary acidic and basic extraction were required. Irreversible adsorptive losses were minimized by using deactivated adsorbents.
