Документ Coal technologies with good prospects(ТОВ "ЛізуновПрес", 2021) Biletskyi, V. S.; Shendrik, T. G.Документ Derivatography as the method for studying structure of water on solid mineral surface(CRC Press, Taylor & Francis Group, USA, 2012) Biletskyi, V. S.; Shendrik, T. G.; Sergeev, P. V.It is proposed to use derivatographic method for investigation of structure of water film on mineral surface. It allows to identify some kinds of moisture, particularly to differ the film moisture from other water types. For the case of hydrophilic materials this method allows to differ some kinds of film water (probably, with great energy of bond and adhesive water).Документ Ennobling of salty coals by means of oil agglomeration(CRC Press Taylor & Francis Group, UK, 2011) Beletskyi, V. S.; Shendrik, T. G.The phenomenon of coal modification at oil agglomeration has been studied, specifically, changing of its structure and physical-chemical properties of surface. It was established: - agglomeration process of coal with size 0-1(3)mm is accompanying by direct adhesive contact of “coal-oil” on 75-80 % from external surface of coal. The high power chemical bonds are formed together with physical bondes in the interphase zone. This modification leads to the increasing hydrophobicity of coal surface and the contrastance of mosaic liophylic-liophobic picture; - internal surface of coal is hydrophobized by diffusing oil agent into pores and fissures. Infiltration phenomenon intensifies this process since light fractions of a binder penetrate into micropores of coal substance; - the changes in supermolecular structure of coal organic mass (COM) have been revealed in oil agglomeration process.Документ Specific modification of salty coals by means of oil agglomeration(1996) Beletskyi, V. S.; Shendrik, T. G.; Kheloufi, A.The phenomenon of coal modification at oil ag- glomeration has been studied, specifically, changing of its structure and physical-chemical properties of surface. It was established:- agglomeration process of coal with size 0-1(3)mm is accompaning by direct adhesive contact of “coal-oil” on 75-80 % from external surface of coal. The high power chemical bonds are formed together with physical bondes in the interphase zone. This modification lead to the increasing hydropho-bity of coal surface and the contrastance of mozaic liophylic-liophobic picture. - internal surface of coal is hydrophobized by diffusing oil agent into pores and fissures. Infiltration phenomenon intensifies this process since light fractions of a binder penetrate into micropores of coal substance. - the changings in supermolecular structure of coal organic mass(COM) have been revealed in oil agglomeration process. The experience carried out on low rank salty coals of Western Donbas.
