SRC-water slurries exhibit properties that qualify them for use as fuel in conventional oil-fired combustion facilities. However, to date, the slurries tested have shown storage instability, which requires constant agitation and recirculation to avoid sedimentation in the storage tanks. High viscosities of the material being evaluated hampered the test performance. A program was instituted to better understand the variables responsible for viscosity and static stability of these slurries. Effective additives and concentrations were determined. This report presents laboratory data demonstrating that solid concentration, particle size distribution, additive concentration, and slurry preparation technique influence the viscosity and stability characteristics of an SRC-water slurry. 7 references, 12 figures, 11 tables.
