The Editorial Board of the scientific journal “Journal of Mining Institute” hereby notifies of the re-traction of the article Mitusova T.N., Kondrasheva N.K., Lobashova M.M., Ershov M.A., Rudko V.A. Influ-ence of dispersing additives and blend composition on stability of marine high-viscosity fuels. Journal of Mining Institute. 2017. Vol. 228, p. 722-725. DOI: 10.25515/PMI.2017.6.722 URL: https://pmi.spmi.ru/pmi/article/view/11500 (accessed 15.06.2026) Retraction date: 07.07.2026. Initiator of the retraction: Editorial Board of the Journal of Mining Institute. Reason for the retraction: identification of violations of publication ethics – detection of dupli-cate publications, as well as manipulation of authorship. Mitusova T.N., Kondrasheva N.K., Lobashova M.M., Ershov M.A., Rudko V.A., Titarenko M.A. De-termination and Improvement of Stability of High-Viscosity Marine Fuels. Chemistry and Technology of Fuels and Oils. 2017. N 6 (604), p. 22-24. URL: https://www.nitu.ru/xttm/2017_6.pdf (accessed 15.06.2026) The retracted publication does not have a link to the published version of the article. Basis for retraction: Editorial Board decision, proceedings N 45 dated 07.07.2026. Authors’ comment: the author (Rudko V.A.) does not deny the existence of significant textual and substantive overlaps between the two articles published in different journals. The author states that the co-authors from the Mining University (Rudko V.A. and Kondrasheva N.K.) were unaware of the work with other journal and the inclusion of a new co-author. The duplicate publication occurred due to uncoordinated actions by the author team. No comments were received from the remaining co-authors.
The article offers a definition of the stability of marine high-viscosity fuel from the point of view of the colloid-chemical concept of oil dispersed systems. The necessity and importance of the inclusion in the current regulatory requirements of this quality parameter of high-viscosity marine fuel is indicated. The objects of the research are high-viscosity marine fuels, the basic components of which are heavy oil residues: fuel oil that is the atmospheric residue of oil refining and viscosity breaking residue that is the product of light thermal cracking of fuel oil. As a thinning agent or distillate component, a light gas oil was taken from the catalytic cracking unit. The stability of the obtained samples was determined through the xylene equivalent index, which characterizes the stability of marine high-viscosity fuel to lamination during storage, transportation and operation processes. To improve performance, the resulting base compositions of high-viscosity marine fuels were modified by introducing small concentrations (0.05 % by weight) of stabilizing additives based on oxyethylated amines of domestic origin and alkyl naphthalenes of foreign origin.
