Specific features of the distribution of vanadium and nickel during fractionation of heavy oil resins were examined using the example of heavy sulfurous oils from the Permian and Carboniferous deposits of the Volga-Urals oil and gas basin (Russian Federation). Fractionation of the resins was performed by silica gel column chromatography, followed by extraction with dimethylformamide (DMF). It was found that, during fractionation by adsorption chromatographic separation and extraction, vanadium and nickel compounds in the resins were predominantly distributed into the components with reduced content of carbonyl and carboxy groups, as well as of aliphatic structures.
