Abstract

Coal–water slurries were prepared with a sub-bituminous coal at varying coal and water ratios using an anionic liquid soap as a surfactant. The slurry properties, viscosity and stability were determined. The rheological properties of the slurries were investigated to ascertain the characteristics of the slurries. The results showed that increasing coal (solid) concentration increased the density of the slurries. Higher density gave rise to more viscous slurries. The behaviour of the slurries changed from Newtonian to non-Newtonian at higher solid concentrations. The slurries with lower solid concentration settled faster than the higher solid concentration slurries.
