Chromatographic study of crude oil
T.S. Idrisov - Institute for Radiation ProblemsThe paper deals with the methods of preparation of crude oil samples and chromatographic analysis of petroleum hydrocarbons (alkanes, monoaromatic compounds, policyclic aromatic compounds), as well as the results of the analysis (chromatograms of the samples and concentrates of hydrocarbons). The analysis have been carried out on Shimadzu GC 2010-plus and PEGASUS 4D GCxGC TOF-MS chromatographs. In the analysis of alkanes, monoaromatic and policyclic aromatic compounds the column temperature comprised 60−330 оС, 40−120 оС and 70−300 оС correspondingly. Silicagel of 100−200 mehs size was used as a sorbent. Developed methods may be applied for the analytical purposes in petrochemistry and corresponding scientific research surveys as well.
