摘要
选择大庆和辽河油浆为研究对象 ,采用超临界流体萃取分馏技术将其切割成窄馏分 ,运用常规分析方法结合质谱和核磁共振氢谱分析 ,得到大庆、辽河油浆窄馏分的饱和分中链烷烃和环烷烃的组成及芳香分中的环系组成 ,并得到了油浆窄馏分及其芳香分的的平均结构。结果表明 ,大庆及辽河油浆窄馏分中芳香分中的各类环状结构随收率呈规律性变化 ,均以四环芳烃含量最多 。
Supercritical fluid extraction and fractionation was used to separate decanted FCC slurries of processed Daqing (Dq) and Liaohe (Lh) crude oils into narrow fractions. Structure and composition of rings in the narrow fractions, their saturates and aromatics were analyzed by mass spectrometry and 1H NMR with conventional methods. The result showed that the tetra aromatics was the major component in the narrow fractions of Dq and Lh decant oil, but aromatic factor of the narrow fractions of Lh decant oil was larger than that of Dq at the same yield level.
