<p>A process of producing a fuel in the form of a dispersion comprising mixing of finely divided coal, with particle size less than 100.mu., with water to form a slurry, adding oil to the slurry and the liquids, subjecting the mixture to violent sonic agitation with an intensity of more than 11.625 watts per cm2, thus producing a stable dispersion, whereby the coal does not settle out, removing any excess oil forming a separate phase, whereby a coal-water-oil dispersion is produced which is stable to storage.</p> |
