This research on the synthesis of composite materials based on heavy oil residues
possesses scientific novelty in several aspects. In the contemporary stage of industrial
development, the increasing waste load of the oil refining industry, along with the growing
demand for high-performance and durable materials, necessitates new approaches for scientific
and technological advancement. For the first time, polymer composites have been developed
based on petroleum porphyrins isolated from asphaltene–resin–paraffin residues. A new
synthesis method for polymer composite materials based on petroleum porphyrins isolated from
the asphaltene–resin–paraffin residues of the Buzovna field has been proposed. This approach
contributes to solving the environmental problem associated with the utilization of heavy oil
residues. The observed spectroscopic changes can be explained by the fact that the
immobilization of the porphyrin occurs through the formation of ionic bonds between the
functional groups of the porphyrin and the positively charged nitrogen atoms of chitosan,
resulting in the formation of an insoluble polyelectrolyte complex. Thus, the results indicate that
only chitosan effectively binds to the porphyrin, whereas methylcellulose remains inert.
