Stable coal-water suspensions and their preparation

Patent ·
OSTI ID:6806773
A method is claimed for a non-settling, coal-water slurry stabilized with an alkali metal soap of a fatty acid. The soap stabilizing agent is preferably prepared by saponification of a fat or fatty oil of either animal or vegetable origin and is diluted with water to the desired concentration without separation of by-products such as glycerine. Thereafter, pulverized coal is added with mixing to form a pumpable slurry which is non-settling at temperatures below the soap gel point.
