Особенности структуры макромолекул асфальтенов нефти Крапивинского месторождения после процессов биологического окисления

Abstract

Oil of the Krapivinsky deposit is studied before and after microbiological oxidation of native soil microflora in a lab environment. Using the IK-spectrometry method there has been determined the fragments of macromolecules of asphaltenes connected through C-O communication in the initial and biodegraded oil. It is established that as a result of biochemical oxidation of oil by association of soil microorganisms and under the influence of abiotic factors of the environment there is destruction of not only saturated, cyclic and aromatic hydrocarbons which are most available to microbic oxidation, but also heavy fractions -the asphaltenes relating to difficult utilized components collapse. It is proved that after the process of biodestruction change of structure and composition of resinous-asphaltene substances is observed.
