Abstract
PURPOSE: To make it possible to prepare a slurry using only a recovered solvent by mixing a high-grade coal containing 3W15% by weight of oxygen with a low-grade coal containing 15% by weight or more of oxygen as a main raw material in a specific proportion in liquefaction of the low-grade coal.
