The composition of aromatic destruction products of Domanic shale kerogen after aquathermolysis

Abstract

In this article we studied a sample of Domanic rock with high kerogen content obtained from Volga-Ural oil and gas basin. A laboratory modeling of the catagenesis process was carried out in order to establish the transformation mechanism of organic matter. The composition of liquid products resulting from kerogen pyrolysis was investigated. The kerogen fragments fall in aromatic hydrocarbons fraction. Alkyltoluenes also exist in saturated hydrocarbon fractions due to alkyl substitutes. The thermal influence changes the ratios of relative content of ortho-, para- and meta-isomers. Heavy aromatic hydrocarbons content increases by increasing temperature and kerogen macroelements ratio changed under thermal effect that is an indicator for maturation process of organic matter.
