Abstract

PURPOSE: To permit the transport of coal powder through a pipeline by dispersing the coal powder in water with the aid of a specific structure of an anionic surfactant as a dispersant for the aqueous slurry of coal powder.
CONSTITUTION: As a dispersant component for the aqueous slurry of coal powder, having good fluidity, an anionic surfactant of the formula I [where R is a C4W22 aliphatic hydrocarbon group, l and n are each 0 to 150 (but l+n=2W150), m is 2W150 (but l+m+n=5W200), p is 1W3 (valency of pair ion M), and M is a mono- or trivalent cation], prepared by a method in which ethylene oxide and propylen oxide and added in blocks or partly blocked state to an alcohol or hydroxylated aromatic compound, and the addition product is subjected to sulfurization followed by salt-forming reaction, is used. Thus, the pipeline transportation of coal powder is made possible because the use of the dispersant makes the fluidity of aqueous slurry of coal powder better.
