Document Type and Number:
Japanese Patent JP5840292
Kind Code:
B2
Abstract:
An industrial process for treating coal in a system to lower ash content, the system comprising first and second water storage tanks, a diesel storage tank, a thermic fluid heater, a thermic fluid storage tank, a thermic fluid pump, a heat exchanger, a thermic fluid expansion tank, a N2 gas cylinder, a reactor, a water pump, and a reflux condenser, the process comprising (i) forming a slurry of coal fines in a N-Methyl-2-pyrrolidone (NMP) with Ethylenediamine (EDA) solution, (ii) maintaining said slurry in the reactor at a temperature of 150° C. to 220° C. and at a pressure of 1 to 4 gauge (kg/cm) for about 1 to 3 hours, (iii) separating a sample of the slurry by coarse filtration in a filter cloth to obtain a filtrate/extract and a residue, (iv) precipitating the coal in water by adding concentrated extract, and (v) separating the coal by filtration.
