发明名称 PROCESS FOR PRODUCING A HIGH CONCENTRATION COAL-WATER SLURRY
摘要 <p>A process for producing a coal-water slurry having a high coal concentration, a low viscosity and a good stability is provided, which process comprises causing the slurry to have a composition of coal particles so that when the particles are divided into 8 fractions, each having a particle diameter range listed below, then the proportions by weight of the particles contained in the respective fractions, relative to the total weight of the particles contained in the slurry can fall within the following numeral value ranges: F1: (DL/4 to DL) --- 29.0 to 50.0 % by weight F2: (DL/42 to less than DL/4) --- 20.0 to 25.0 % by weight F3: (DL/43 to less than DL/42) --- 12.0 to 15.0 % by weight F4: (DL/44 to less than DL/43) --- 6.0 to 10.0 % by weight F5: (DL/45 to less than DL/44) --- 3.0 to 12.0 % by weight F6: (DL/46 to less than DL/45) --- 1.5 to 5.2 % by weight F7: (DL/47 to less than DL/46) --- 0.8 to 4.0 % by weight F8: (DL/4 to 0) --- 0.7 to 9.0 % by weight wherein DL represents the maximum particle diameter.</p>
