Abstract

PURPOSE: To granulate pulverized coal-containing coal in water with a small amount of oil by lower energy simply, by adding a specific block type polyether as a binder auxiliary to a slurry of coal and water, adding an oil as a binder to the slurry, blending the slurry without emulsifying it.
CONSTITUTION: Preferably 0.01W1wt% block type polyether having a molecular weight of 2,200W10,000 and a content of ethylene oxide of 3W35wt% as a binder auxiliary is added to a slurry of pulverized coal-containing coal and water, and oil as a binder is added to the slurry, and the coal is granulated in water. To obtain the polyether, 3W4C alkylene oxide is added to a polyamine, and ethylene oxide is added to the prepared compound.
EFFECT: Granulated coal having reduced ash content and low water adsorption is obtained.
