Abstract

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 2-4 rings, is a good feedstock for making needle coke. The pyridine-soluble fraction cannot be used for these purposes because it contains more aromatic hydrocarbons with 5 or more rings. The composition of the studied samples determines their different behavior in carbonization (coking).
