Abstract (en)

[origin: EP0029712A2] An in-line method for the beneficiation of coal and the formation of a coal-in-oil combustible fuel wherein the coal is pulverized (28) mixed with water to form a slurry (1), micro-agglomerated with light oil (4, 5, 6) to dissociate (10) a large amount of inorganic impurities and some water, agglomerated (74) with heavy oil to form relatively larger agglomerates and dissociate (18) mainly water with some inorganic impurities, and then mixed (22) with further heavy oil to form the coal-in-oil combustible fuel.
