Abstract: A pipeline pumpable coal-water slurry having a novel combination of coal particles and carrier water is prepared by a method wherein the particle sizes and their distribution are controlled in accordance with a particle size distribution formula which is especially beneficial for providing a novel coal compact with a minimum amount of void space between particles and a maximum amount of particle surface area with an advantageous amount of colloidal sized particles present. These features combine to enhance the dispersing effects generated by electrolytes and/or dispersing agents selected and added to the coal compact and/or slurry to provide a near maximum zeta potential to the particles in the slurry and to provide low viscosity to the resulting yield pseudoplastic coal-water slurry. Brookfield viscosities obtained, e.g. 1000 cps, or less, at 60 rpm with 75 wgt.% coal, dry basis, make the coal-water slurry especially advantageous for transport by pipeline over long distances. The coal-water slurry can be provided at a high coal content so that the slurry can be burned directly without need for dewatering at its destination.

Abstract: A deashed coal-water slurry and process for preparing the same containing 65-85 percent of solids and 0.01-2.4 weight percent of dispersing agent. The slurry is comprised of a coal compact whose coal particles have a particle size distribution in substantial accordance with a specified formula. The coal-water slurry has a relatively low viscosity of less than 4,000 centipoise at a 75 percent solids content and, when it is pumped at either a constant or an increasing shear rate, its viscosity decreases. Also disclosed are a pumping process and an electrophoretic deashing cell and process.

Abstract: SLURRY OF COAL-WATER-ANIONIC ORGANIC SURFACTANT This invention relates to a method for making and utilizing a novel partially de-ashed, pseudoplastic coal-water slurry for pumpline conveyance to coal-water slurry combustion and gasification processes. The novel coal-water slurry is deflocculated while retaining pseudoplastic rheology by adding to pulverized coal particles dispersed in water a deflocculating amount of an anionic organic surfactant, preferably in the presence of alkali.

Abstract: A grinding mixture is disclosed which can be used to prepare a high density, stable, carbonaceous solids-liquid slurry which has a relatively low viscosity. The grinding mixture has a pi of 5 to 12 and contains about 60 to 82 volume percent of solid carbonaceous materiel, from about 18 to 40 volume percent of carrier liquid, and from about 0.01 to about 4.0 weight percent of dispersing agent.
