In this paper we discuss the possible clean coal applications of colloidal dispersions of coal in water (CCW) that we manufacture with a proprietary wet-comminution device.These dis persions are a new material because the coal particles do not settle but are held in suspension by Brownian motions.The closest coal water slurries used previously are dispersions of micromzed coal with mean particle sizes greater than fifteen microns; these dispersions are not colloidal because the parti cles settle rapidly under gravity leaving clear water behind.A new material like CCW has a possibly vast but unknown field of applications in improvements and strategies for new clean coal technologies.
