alphaville clothing The work is relevant due to the need of obtaining detailed information on composition and structure of aromatic hydrocarbons and heteroorganic compounds of oily components in petroleum occurring in Krapivinskoye oilfield, Upper Jurassic deposits in Tomsk region, to solve the problems of obtaining high-quality petroleum products, based on oily components.In addition the accumulation of data on the nature of these classes of compounds is essential for understanding the fundamental laws of petroleum system genesis.The aim of the research is to identify the composition and structure of aromatic hydrocarbons and heteroorganic compounds of oily components in petroleum from Krapivinskoye oilfield.Methods: liquid-adsorption chromatography, thin layer chromatography, acid extraction, gas chromatography with mass-spectrometer detector.Results.
Using a complex of up-to-date analytical methods the authors have found that aromatic hydrocarbons of oily components in petroleum from Krapivinskoye oilfield are represented mpu63zm/a by a number of compounds of the following series: benzene, naphthalene, phenanthrene, chrysene, pyrene, benzo-, dibenzochrysene and benzo-, dibenzopyrene.Sulfur-, nitrogen- and oxygen-containing structures are among the heteroorganic compounds.Alkyl-substituted thiophenes and benzothiophenes, holonuclear dibenzo- and naphthoben-zotiophenes and their alkyl homologues, mono- and bicyclic sulfides, alkyl derivatives of quinolines, benzo-, dibenzoquinolines, azapyrenes, thiopheno- and benzothiophenoquinolines, carbazoles and dibenzocarbazoles, unsubstituted and alkyl-substituted dibenzo- and naphthobenzofurans were identified in their composition.The presence of highly alkylated naphthalenes in the composition of oily components is a special feature of this petroleum.Low values of maturity indicators, calculated on the composition of polycyclic aromatic hydrocarbons and cyclic aromatic sulfur compounds, indicate that the investigated petroleum from Upper Jurassic Krapivinskoye oilfield was not subjected to significant catagen transformations.
