Abstract
PURPOSE: To improve the liquefaction rate of coal, by a method wherein products resulting from the liquefaction of coal are fractionated according to boilding points, components requiring a hydrogenation treatment are hydrogenated and then mixed with other component, and the resulting mixt. is used as a solvent for the liquefaction of coal.
CONSTITUTION: Products resulting from the liquefaction of coal are fractionated according to boiling points into component (A) which boils at 200W210°C and has a hydrogen-donating property without hydrogenation, component (B) which boils at 211W230°C and in which liquefaction rate is low when it is used as such, but the component after a hydrogenation treatment is rich in coal-dissolving power and improves dissolving performance, and component (C) which boils at 231°C or higher and has similar properties to the component (B), but whose hydrogenation rate is slow. The component (B) and (C) are hydrogenated separately, and then mixed with the component (A). When the mixt. is used as a solvent for the liquefaction of coal, the liquefaction of coal can efficiently be conducted.
