Abstract

A process for making fluid, stable slurries of finely divided coal in water and products thereof, which can be sufficiently highly loaded to serve as a fuel, comprises: a. Admixing: (i) ultrafine coal particles having a maximum size (as determined by a sedimentation technique based on Stoke's law) of 10 mu m MMD (Mass Median Diameter) in an amount comprising more than 30% and up to 50% by weight of the slurry, (ii) larger coal particles within the size range of from 20 to 200 mu m MMD in an amount sufficient to provide a desired total coal concentration in the slurry, (iii) water, and, (iv) a minor amount of dispersant consisting of an alkaline earth metal salt of organo-sulfonate in which the organic moiety is multi-functional, and b. subjecting the mixture to high shear at a rate of at least 100 sec.
