The processes of photochemical transformation of oils extracted from contaminated soils and the surface of reservoirs have been studied using ESR and low-temperature photolysis. Under the influence of ionizing radiation, polycyclic aromatic hydrocarbons, asphaltenes and resins. It has been shown that in the presence of photosensitizers (polycyclic aromatic hydrocarbons) in organic compounds (alcohols and paraffins) initiate photochemical processes in organic compounds with the formation of alkyl radicals and atomic hydrogen, which reacts with hydrocarbons to form the radical R• and a hydrogen molecule (H2). The process follows the mechanism of two-photon absorption. The R• radicals easily react with O2 to form a peroxide radical, then the process proceeds by a chain reaction mechanism. The R• radicals easily react with O2 to form a peroxide radical, then the process proceeds by a chain reaction. Shown that in the presence of izo-compounds in oil, substituted aromatic hydrocarbons are formed. Methylperinaphthene radicals are registered in the products of secondary oil refining (cracking, pyrolysis). The photochromic properties of this radical have been studied. Resis asphalten and asphaltenes play a role in the photochemical and photo-oxidative processes of light oil systems. The process of decomposition into radicals occurs by a single-quantum mechanism with a relatively low energy (2 ev). Polycyclic aromatic hydrocarbons with the participation of naphthene-paraffin hydrocarbons and olefins during irradiation also undergo transformations with the formation of ion radicals, endoperoxides, quinones, phenols.
