Coal liquefaction with coal tar solvent

Patent ·
OSTI ID:6934873
A method is described of liquefying coal, comprising: mixing solid coal with a process solvent comprising coal tar material which has been at least partially hydrogenated under conditions which selectively hydrogenate aromatic coal tar components to hydroaromatics and which preserve the integrity of organonitrogen coal tar components, to produce a coal-solvent slurry; treating the coal-solvent slurry under coal-liquefying conditions in a liquefaction zone to produce a solution containing coal liquefaction products; and recovering coal liquefaction products from the solution.
