Coal-water slurry and method for its preparation
Patent
·
OSTI ID:5729107
A deashed coal-water slurry and process for preparing the same containing 65-85 percent of solids and 0.01-2.4 weight percent of dispersing agent. The slurry is comprised of a coal compact whose coal particles have a particle size distribution in substantial accordance with a specified formula. The coal-water slurry has a relatively low viscosity of less than 4,000 centipoise at a 75 percent solids content and, when it is pumped at either a constant or an increasing shear rate, its viscosity decreases. Also disclosed are a pumping process and an electrophoretic deashing cell and process.
