| Résumé: | Title screen Presented are the results on the study of insoluble products obtained at autoclave thermolysis of resins and asphaltenes of the oil from the Usinskoye oil field in an argon atmosphere at 160-650°С. A high yielded chloroforminsoluble thermolysis product obtained from the resins of heavy high-sulfur oil at 250°C significantly differs from products obtained from resins and asphaltenes at 450 and 650°C but according to the results of Rock Eval and 'on-line' flash pyrolysis (600°C, 20 s), and elemental analysis it is similar to 'asphaltene-like' substances. Their formation is probably due to the cleavage at 250°C of the most labile S-S or C-S bonds in the resin molecules followed by generation and recombination of macroradicals. The thermal destruction of these substances at higher temperatures (450 and 650°C) is accompanied by the formation of more carbonized coke-like products.
