Abstract

PURPOSE: To increase the sedimentation rate of coal by agglomerating pulverized coal, by a method wherein a specified sulfosuccinate is added to an aq. slurry of the pulverized coal formed for the transport of the coal with a pipe line and shipping.
CONSTITUTION: Coal is pulverized and suspended in water to obtain an aq. slurry which is then transported with a pipe line or shipped. Then to the transported or the shipped slurry is added a sulfosuccinate of the formula (wherein R, R' are 4W22C alkyl, alkenyl; n is 1W3; M is Li, Na, K, Mg, Ca, Ba or Al) in an amount of 10W30,000ppm based on the amount of coal (on a dry coal basis) to precipitate coal and to remove water.
EFFECT: The grab-unloading of the precipitated coal is possible in the unloading of the coal from a ship. Alternatively, the coal can be unloaded from a ship by means of a pump by adding water to coal to reslurry it.
