Abstract

PURPOSE: An additive for granulation and deashing of an aqueus slurry of finely pulverized coal with an oil, containing a specific amide compound, etc., and capable of reducing the deashing cost.
CONSTITUTION: An additive containing (A) an amide compound of formulaI(R1 is carboxylic acid residue; R2 is hydrocarbon group or formula II; R4 is residue of a polyamine; X1 and X2 are H or acyl group; R3 is H, hydrocarbon or acyl group; at least one of R1, R2 and R3 is ≥5C; m1 is an integer ≥1), e.g. a monoamide, and if necessary (B) a surfactant, preferably an alkylolamide nonionic surfactant, and/or an inorganic electrolyte, preferably an alkali metallic salt. The amount of the component (A) is 1ppmW5wt%.
EFFECT: Reduced adhesive moisture in granulated materials and dehydration cost.
