Abstract

PURPOSE: To provide an additive which can sufficiently remove ash and makes the removal of water on granules easy when said additive is added to an aq. slurry in wet-process granulation of fine coal powder, consisting of a nonionic alkylolamide surfactant or said surfactant and another surfactant.
CONSTITUTION: In a wet-process granulation of fine coal powder, an alkylolamide surfactant of the formula (wherein R is 5W24C acyl residue; A is 2W4C alkylene; R' is (AO)nH, hydrocarbon group; m is an integer of not less than 1, n is o or an integer of not less than 1, m+n=1W100) or said alkylolamide surfactant and another nonionic surfactand and/or an anionic surfactant is/are incorporated into an aq. slurry. Then an oil is added to the slurry. Ash can sufficiently be removed, and at the same time, the amount of the oil and granulation energy can be reduced, and thus, the cost of granulation is reduced. The adhesive moisture on granules is lowered, and hence the cost for dehydration is reduced.
