new materials for coal liquefaction

  • COAL LIQUEFACTION, Volume II - Assessment

    Coal liquefaction is the conversion of coal to liquid hydrocarbon products. The major products of most coal liquefaction processes are condensed aromatic liquids; however, some gases and solids are also produced, depending on the type of coal, the process, and the operating conditions used [2].

     · Chromatography/mass spectrometry (GS/MS) was used to study toluene-soluble (TS) and pyridine-soluble (PS) fractions obtained from coal liquefaction residue by solvent extraction. It was found that the toluene-soluble fraction, containing mainly polycyclic aromatic hydrocarbons with 4 rings, is a good feedstock for making needle coke.
