Abstract:
PROCESS FOR LIQUIFYING COAL Disclosed is a process for manufacturing reformed coal which comprises the steps of (a) dispersing coal into a mixed oil which is comprised of a coal oil having a boiling point between about 150.degree.C. and 500.degree.C. and a petroleum oil having a boil-ing point higher than that of kerosene; (b) subjecting the coal and oil dispersion to hydrogenation conditions sufficient to depolymerize the coal; (c) separating a substantially liquified coal solution from the product of hydrogenation; and (d) distilling the liquified coal solution to recover a reformed coal. Preferably, a portion of the coal oil is recycled from the distillation stage and a portion of the hydrogen needed for hydrogenation is produced from light fractions from the distillation stage.
