ABSTRACT:
Particulate coal is rendered less subject to spontaneous ignition by simultaneously spraying or otherwise contacting it and cooling it with an aqueous emulsion in water of a light cycle oil, heavy cycle oil, clarified slurry oil, durene, and other carbonaceous materials derived from coal liquefaction and petroleum refining. Aqueous polymer emulsions and oxidation inhibitors can also be used.
