<p>A process for liquefying a particulate coal feed to produce useful petroleum-like liquid products by steps which include: (a) admixing said coal feed, a solvent, particularly a non-donor solvent, and a quinone compound, preferably an orthoquinone or admixture of quinone compounds, to form a coal liquid slurry, and then (b) contacting said coal liquid slurry with molecular hydrogen in a liquefaction zone at temperature and pressure sufficient to hydroconvert and liquefy the coal. In accordance with a preferred embodiment, the product from the liquefaction zone is separated by distillation into fractions inclusive of fractions boiling within about the 350-850.degree.F. range, and preferably within about the 400-700.degree.F. range, which can be recycled to the coal liquefaction zone for use in slurrying the coal.</p> |
