Abstract

PURPOSE: To obtain solvent-refined coal of a high softening temp. from a dilute soln. at one step, by separating a solvent by flushing solvent-refined coal prepared by thermal cracking at a high hydrogen pressure in the solvent, and recycling a certain amt. of the solute to the soln. of the solvent-refined coal.
CONSTITUTION: A soln. of solvent-refined coal is introduced via line 1 to reservoir 2, in which it is held, and led via line 3 to pump 4, by which it is pressurized to a certain pressure, and then flushed via line 6 to evaporation column 7. A solvent is withdrawn via line 8 and solvent-refined coal via line 9. A cartain amt. of the solvent-refined coal is recycled from the column 7 to the reservoir 2 via line 10 and led to furnace 5. 30wt% or less soln. of the solvent-refined coal is subjected to the treatment. The flushing pressure is pref. 30W100mmHg. The temp. of the solvent- refined coal flushed into a flushing region should be 430°C or lower, and the lowermost temp. depends on desired softening temp. of the solvent-refined coal, concentration of the soln. of the solvent-refined coal and pressure in the flushing region.
