    摘要: A process of producing a solvent useful in coal liquefaction which includes separating the heavy liquid produced from the liquefaction of coal into a fraction boiling at 200.degree. to 210.degree. C., a fraction boiling at 211.degree. to 230.degree. C., and a fraction boiling at not less than 231.degree. subjecting the fraction boiling at 211.degree. to 230.degree. C. to a hydrogenation treatment to produce a hydrogenated fraction, mixing the hydrogenated fraction with the fraction boiling at 200.degree. to 210.degree. C. to form a resultant mixture, and mixing a portion of the resultant mixture with a portion of the fraction boiling at not less than 231.degree. C. Alternately, the solvent is produced from the heavy liquid by separating it into a fraction boiling at 200.degree. C. to 210.degree. C., a fraction boiling at 211.degree. C. to 230.degree. C., a fraction boiling at 231.degree. C. to 250.degree. C., a fraction boiling at 251.degree. C. to 350.degree. C. and a fraction boiling at not less than 351.degree. C., subjecting each of the middle three fractions to a hydrogenation treatment to form three hydrogenated fractions, mixing the three hydrogenated fractions with the fraction boiling at 200.degree. C. to 210.degree. C. to form a resultant mixture, and mixing the resultant mixture with a portion of the fraction boiling at not less than 351.degree. C.
