The main goal of this work is the investigation of the processes of wetting, electrokinetic properties of interfacial carbon environment in the presence of pairs of different chemical nature, as well as the rheological behavior obtained disperse systems. Research methods rheology, electrokinetic.The main results еhe surfactants nature, electrolytes, charge and ionic strength of the solution significantly affect the zeta potential of particles in an anthracite aqueous environment. It is found that the adsorption of the singly charged electrolytes on coal surface zeta potential increases in the negative values when using doubly charged electrolytes zeta potential comes in the negative range of values, and in the presence of triple charged electrolytes in solution the surface recharging occurs. As the dispersing agent of aqueous suspensions of coal is better to use anionic and nonionic surfactants and mixtures thereof. When co-administered alkaline electrolytes and surfactants caused the synergistic effects and reducing the dynamic viscosity of disperse systems coal-water fuel.Scope of application - energetics.
