Abstract

High solids brown coal suspensions were prepared with concentrations approaching those of bituminous black coals. The high surface hydrophobicity, inherent water content and macroporosity were modified by mechanical and chemical means to produce a systematic improvement in solids concentration attainable at reasonable apparent viscosities. Both raw brown coal and modified brown coal suspensions show shear thinning behaviour resulting in lower viscosities at higher flow rates. All coal suspensions displayed a yield stress once sufficient solids concentration was achieved. This yield stress can be used to aid suspension stability. To fully understand the colloid chemistry and structural characteristics that permit achievement of high solids coal suspensions, these were produced and characterised with no additives that could mask these fundamental effects.
