ABSTRACT:
A process for removing ash from coal comprising the steps of pulverizing the coal to fine particles, admixing water with the finely divided coal to prepare an ash-containing slurry of finely divided coal, mixing with the slurry an oil and seeds in the form of oleophilic solid grains and serving as granulating nuclei to granulate the finely divided coal, separating the resulting granules from the mixture and washing the granules with water to remove the ash, and disintegrating the washed granules to obtain a deashed coal and recover the seeds for reuse.
