Abstract

Dispersion containing water, pulverized coal and additives, which is stable for storage, pumpable and combustible by conventional technique applied for liquid fuels. The coal content amounts to at least 55 % by weight. The dispersion contains as an additive a ionic surfactant polymer with at least one hydrophobic part with great affinity to the coal surface and at least one hydrophilic part based on ethylene oxide with the mole weight exceeding 1,000. The charge of the polymer is preferably zwitterionic or cationic.
