ABSTRACT:
An increased yield of hydrogenated liquid product is obtained from coal by contacting the feed coal with a hydrogen-donor solvent and a hydrogen-containing gas in a series of two or more liquefaction zones arranged in series and operated in such a manner that the temperature in each zone increases from the initial to the final zone. The effluent from each liquefaction zone is passed to the next succeeding higher temperature zone in the series. Liquid hydrocarbonaceous products are recovered from the effluent withdrawn from the last zone. Hydrogen-donor solvent may be produced in the process by catalytically hydrogenating at least a portion of the liquid product from the last liquefaction zone, recovering a liquid fraction from the product of the catalytic hydrogenation and separating a hydrogen-donor solvent from the liquid fraction.
