Abstract
PURPOSE: When powdery coal is granulated by a wet method, a gas is introduced into or evolved in the slurry to increase the affinity between the binder of oil and the coal particles carrying bubbles on the surface and facilitate the granulation using a small amount of oil and little energy.
CONSTITUTION: An aqueous slurry of powdered coal is mixed with oil as a binder and the pwdered coal is granulated in water wherein fine bubbles are introduced or evolved in the slurry by forcing a gas from a pipe into the lower part of the slurry or bubbling and the wet granulation is conducted. When a surfactant is added to the coal slurry as a granulation accelerator, this effect is further intensified. As the surfactant, is preferably used a sulfate ester salt of formula I (R1 is 4W22C aliphatic group; a, b, c are 0W50) or a sulfosuccinate ester salt of formula II (R2, R3 are H, 4W22C alkyl).
