Coal is rendered less subject to abrasion and disintegration by reducing it to a 0.2 to 0.5-inch particle size and drying it in a drying zone at a temperature of 200 DEG to 230 DEG F. for 3-7 minutes while simultaneously applying a treating agent which can be a light cycle oil, heavy cycle oil, clarified slurry oil, a petroleum or coal derived distillate or residuum, a solution of durene in gasoline and mixtures of two or more of the preceding.
