Реферат: It has been shown for the first time that the high-temperature treatment of heavy oil with a high content of asphaltenes at 350–450 °C without a catalyst or H2 leads to the formation of new vanadium(IV) porphyrin complexes detected by ESR spectroscopy. In anisotropic spectra of treated oil samples recorded at 130 K, together with the signals of the porphyrin complex of the vanadyl ion, VO2+, another component with distinct g and A spin Hamiltonian parameters was observed. A comparative analysis of the resonance parameters of the revealed complexes allowed us to unambiguously identify them as the thiovanadyl (VS2+) porphyrins formed during the thermal treatment. Thus, the formation of thiovanadyl porphyrins from vanadyl porphyrins in asphaltene-containing heavy oils at high-temperature processing has been experimentally proven for the first time.
