ABSTRACT:
An improved process for liquefying coal and similar solid carbonaceous materials wherein the liquefaction is accomplished in a plurality of zones or stages and wherein the temperature is increased either linearly or nonlinearly in the first zone or stage, aromatics which are produced, liberated or contained in the solvent are separated after the first zone or stage and the liquefaction is continued in at least one other stage, at a temperature at least as high as the final temperature in the first zone or stage. In a preferred embodiment, the temperature in the first stage will be increased at least 50.degree. F. The improved process results in a higher conversion of carbon contained in the coal or similar solid carbonaceous material to liquid products.
