摘要： A process for improving the properties of a hydrogen donor coal liquefaction solvent employed in a coal liquefaction process which comprises separating said coal liquefaction solvent into a first fraction boiling in the range from about 350.degree. to about 675.degree. F., and a second fraction boiling in the range from about 675.degree. F. to about 1000.degree. F., hydrogenating said first fraction at a temperature ranging from about 600.degree. to about 800.degree. F., under a pressure of about 500 to 4000 psig, hydrogenating said second fraction at a temperature ranging from about 600.degree. to 700.degree. F. at a pressure from about 500 to 4000 psig and combining said hydrogenated first and second fractions to provide a coal liquefaction solvent having an increased concentration of hydrogen donor components.
