Abstract

PURPOSE: Air bubbles of extremely fine sizes are contained in a slurry composed of coal, water and a surfactant to produce a coal-water slurry containing air bubbles stably and showing good flowability.
CONSTITUTION: Bubbles of a gas such as air of extremely fine sizes are contained in a slurry composed of coal, water and a surfactant, preferably a sulfate ester salt of formulaI(R1 is 4W22C aliphatic group; a, b, c are 0W50 where a+b+c is 100 or less, x is 1W3; M1 is mono-, di- or trivalent cation) or a sulfosuccinic ester of formula II (R2, R3 are H; y is 1,2; M2 is mono- or divalent cation) by 5W100vol% to give the objective slurry. The gas is contained in the slurry, preferably by adding 40W90wt% of powdered coal to water containing a surfactant dissolved or dispersed therein under bubbling a gas with pressure under stirring.
