RHEOLOGICAL PROPERTIES OF COAL WATER SLURRIES CONTAINING PETROCHEMICALS

ABSTRACT
In this paper, the rheological properties (viscosity, shear stress, and lamination) of the promising coal-water slurries containing petrochemicals based on filter cakes have been investigated experimentally. The latter are a mixture of water and solid organic wastes produced during coal preparation. It was established that the rheological properties of coal-water slurries containing petrochemicals depend on concentrations and properties of the main components (liquid and solid, flammable, and non-flammable), wetting agents (plasticizers), as well as the storage time and conditions. The rheological properties of the fuel slurries under study were compared with the known properties of coal-water slurries based on different ranks of coal and found to match or even surpass them. Coal processing wastes have high potential as prospective components of coal-water slurries containing petrochemicals in terms of not only their environmental, economic and energy performance but also their rheological properties.
