Abstract:
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.
