The joint cracking of mechanically activated oil shale and petroleum residue was studied. The introduction of oil shale allowed to intensify the process of destruction of high-molecular components of the petroleum residue. In the obtained liquid thermolysis products, oils predominate from 40,2 to 81,1% wt. With an increase in the share of oil shale in the cracking products, the proportion of asphaltenes decreases from 4,2 to 2,8% wt, and of tar from 6,7 to 4,8% wt. In gaseous products, the proportion of carbon dioxide and carbon monoxide increases markedly. The introduction of mechanically activated oil shale also affects the fractional composition of thermolysis products; the proportion of gasoline (IPB – 200 °С) and diesel fractions (200–360 °С) changes

The composition of saturated and aromatic hydrocarbons and the structural-group characteristics of resins and asphaltenes in four oils of northern West Siberia have been studied. As follows from the distribution of hydrocarbons, the Cenomanian oils (pools in the beds PK and K2c) of the Russkoe, Barsukovskoe, and Pangodinskoe fields are naphthenic and the Pangodinskoe oil sample from the Lower Cretaceous pool (bed BN9) is methanoic. The hydrocarbon composition pattern of the saturated fraction and the characteristics of the heterocyclic components of these oils point to their formation from dispersed organic matter of mixed genesis in the oil window. Hence, the oil source rocks are localized at depths much greater than the present-day level of the oil pools. Secondary (cryptohypergene) alterations (oxidation and biodegradation) in the shallow-depth oils determined their current predominantly naphthenic composition and considerably hamper reconstruction of the types of initial dispersed organic matter. We assume that the mixed genetic type of the studied oils is not only due to their heterogeneous source but also due to the reorganization of primary oil pools at the Cenozoic stage of tectogenesis. The Cenomanian Russkoe and Pangodinskoe naphthenic oils are saturated with adamantoids, which can be selectively accumulated during biodegradation.

We summarize the results of our long-term research into the composition of alkyl derivatives of mono-, bi-, and tricyclic aromatic hydrocarbons of 113 crude oils from the Cenozoic (Sakhalin, Pannonian Basin (Serbia), China, and Vietnam), Cretaceous (West Siberia, Mongolia, China, and Saxony), Jurassic (West Siberia and Saxony), and Paleozoic (West Siberia, East Siberia, and Timan–Pechora and Volga–Ural petroliferous provinces) deposits localized at depths from 200 to 4500 m. To identify compositional similarities and differences of crude oils from deposits of different ages, we processed the obtained data on the individual composition of alkanes, alkyl benzenes, alkyl naphthalenes, and alkyl phenanthrenes by principal-component analysis. The analysis has revealed the regularities of changes in the content and composition of alkyl aromatic hydrocarbons in crude oils depending on the age of the enclosing deposits.
