Изменение состава нефти при воздействии порошком железа

Abstract

It is shown that an introduction of iron powder, modified by Ni{2+} and Co{2+} ions, into the oil system results in an increase in the content of resins and asphaltenes, where the fraction of asphaltenes increases and that of resins decreases, an increase in the content of carbonyl functional groups in all components, and in a decrease in the number of sulfoxide groups in the resins and asphaltenes. Oily and resinous components of the oil treated with iron powder are characterized by increased aromaticity. The compositions of hydrocarbons and heteroatomic compounds of the samples under study contain the same sets of compounds. A twofold decrease in the number of dibenzothiophene derivatives is typical for the oil samples studied.
