The main goal of this work is the research of processes of mechanical activation, electrokinetic properties of interfacial carbon environment in the presence of surfactants of different chemical nature, the rheological behavior of disperse systems, as well as the development of technology producing fuel dispersion systems. Research methods rheology, electrokinetic.The main results еhe the methods of regulation hydrophilic-hydrophobic properties of the different stage metamorphism coal surface by the surfactants and polyelectrolytes result found that as dispersant reagents fuel dispersion systems of coal-based is better to use anionic and nonionic surfactants, and mixtures thereof. Plastifying properties have polyelectrolytes containing aromatic ring structure. The efficiency of the method of mechanochemical modification of the surface of coal in comparison with a conventional homogenization process. The optimal concentration of surfactants in which the systems have not only the lowest viscosity, but the highest stability. As well developed flow diagrams for fuel dispersion systems, thanks to which it is possible to improve the rheological properties and increase the stability of these systems. The prepared on the proposed system technologies have been successfully tested in pilot installations "ANA-TEMS" company.Scope of application - energetics.
