Abstract

PURPOSE: To obtain the depolymerized product of coal in high yield and at low cost by dissolving coals in a specific solvent for coal liquefaction and then by recovering the depolymerized product of coal and the solvent.
CONSTITUTION: A solvent for coal liquefaction, having a H/C atomic ratio of 0.90W1.20, is obtained by bringing a coal-based solvent into contact with a hydrogenation catalyst consisting of a combination of a metal oxide or sulfide of the VI-B group and a metal oxide or sulfide of the VIII group at 300W470°C under a hydrogen pressure of 10W300kg/cm2. Then, the solvent thus obtained and coal powder are mixed in a solvent/coal mixing ratio of 1W10:1 to a slurry, and the slurry is heated at 300W500°C for 10W120 min under a hydrogen partial pressure of 10kg/cm2 or more to dissolve organics present in the coal on one hand and to remove insoluble substances such as organics, and undissolved coal, as needed on the other. Then, the solution is heated at 200W500°C to recover 100wt% or more of the solvent used and also to obtain the depolymerized products of coal. The recovered solvent is redused by circulation.
