Abstract

The aim of the research is to obtain coal-water slurry, corresponding to modern requirements, with a minimum of energy. The paper presents the characteristics of coal-water slurries prepared by plasma and electric discharge methods. As a raw material used D-grade coal. By electron scanning microscopy was determined the chemical composition of suspensions and removed micrographs of the surface. Micrographs show that the samples processed through both methods have pronounced dispersed structure, compared with the original. Elemental analysis showed a significant reduction in the oxides of sulfur and nitrogen. The results obtained make it possible to draw a conclusion about the availability of receiving coal-water slurries with new plasma and electric-discharge methods.
