%X Low-temperatere coal tar sample from Lurgi coal gasification process was fractionated by liquid-liquid partition and liquid chromatography on a silica gel column to provide 11 fractions. Subsequently, high resolution separation of individual components was achieved by using capillary gas chromatography. Over 400 compounds, including aliphatic hydrocarbons, polycyclic aromatic hydrocarbons, aza-arenes, ethers, keton-es, alcohols, phenols, carboxylic acids, amines etc., were tentatively identified by GC-MS and checked with gas chromatography retention indices. Aliphatic hydrocarbons, polycyclic aromatic hydrocarbons, aza-arenes and phenols were quantitatively analyzed by capillary GC. The characteristics of the low-temperature coal tar from Largi gasification process were discussed in comparison with those of the high-temperature coal tar.
