In this paper, the rheological properties (viscosity, shear stress, and lamination) of the promising coal-water slurries containing petrochemicals (CWSPs) 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 CWSPs 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 CWSPs in terms of not only their environmental, economic and energy performance but also their rheological properties.
