采用实验方法对比研究了细粒硅胶柱与现行的石油行业标准方法分离原油中的饱和烃和芳烃的组成差异。通过实验发现,用细粒硅胶充填的柱子能够使饱和烃和芳烃完全分离,烷基苯和单芳甾组分完全进入到了芳烃中,而现行的石油行业标准方法不能完全将烷基苯和单芳甾组分冲入芳烃馏分。精密度实验结果表明误差不超过5%,证明了该方法的稳定性。

This paper mainly use fine-grained silica gel to separate saturated and aromatic hydrocarbon in oil or extraction.By experiment,the method can separate saturated and aromatic hydrocarbon completely.Isomeric hydrocarbon increased in saturated hydrocarbon,alkylbenzenes and monoaromatic steranes group are also entered into aromatic hydrocarbon completely.The method makes up the deficiency in common method to separate saturated and aromatic hydrocarbon.In order to verify the reliability of the experiment,the author made a precision experiment at the same time,the error no more than 5%,This proved that the experimental apparatus is stable and the results is credible.
