Abstract

PURPOSE: A coal-water slurry that contains a sulfonated polycyclic aromatic compound or its salt and a hydrocarbon oil, thus having high dispersion stability and causing no hard cake formation by the compaction of the precipitate after standing for a long period of time.
CONSTITUTION: (A) A sulfonated polycyclic aromatic compound which may bear hydrocarbon groups as substituents or its salt, preferably a formaldehyde condensate with naphthalenesulfonic acid (about 0.001W0.1wt%, preferably 0.01W 0.5wt%) and (B) a hydrocarbon oil (such as A heavy oil, B heavy oil, C heavy oil, light oil or kerosine) are added to a coal-water slurry as dispersants to give the objective slurry.
