Beschreibung
Zusammenfassung:	PURPOSE:To obtain oil-containing deashed coal granule which can be dehydrated easily with a screen and has water-absorption preventing property, by making the surface of dried coal particle oleophilic, converting the particle to aqueous slurry, adding an oily substance as a binder to the slurry, and granulating the particles in water. CONSTITUTION:The surface of coal particles such a brown coal, etc. dried to a water-content of
