Givens, E N; Kang, D

A process is described for preparing a stabilized coal particle suspension of ground coal in an aqueous media comprising the steps of: providing an aqueous media substantially free of oxygen and acid-forming gases; reducing, in a nonoxidizing atmosphere, the particle size of the coal to be suspended in the aqueous media to a size sufficiently small to permit suspension in the aqueous media; and admixing the coal of reduced particle size with the aqueous media to release into the aqueous media coal stabilizing constituents indigenous to and carried by the coal particles of reduced particle size to form a stabilized coal particle suspension.
