Coal–water slurry is simply produced by mixing pulverized coal with water together with a small amount of a surfactant and a stabilizing agent. The coal particle diameters used are generally about 100 μm or slightly less, but in micronized coal, particle sizes are of the order of microns (micrometers). The resulting liquid looks like black

Shangwan coal is a lowrank coal from inner Mongolia. Shangwan coal particles show electronegativity in the slurry, because there are many oxygenated functional groups, such as the carboxyl group, hydroxyl group, and carbonyl group on the surface and in the core of the particles. Besides, because these functional groups are all hydrophilic, Shangwan coal shows strong waterretaining capacity
