Abstract: Quinoline insoluble is a kind of macromolecular carbon particle component in the coal tar pitch, which has important influence on the properties and application of coal tar pitch. In order to a detailed analysis of quinoline insoluble, three kinds of quimoline insolubles (QI-M, QI-O and QI-N) which obtained from varies coal tar pitch have been used as raw materials. Briefly, QI-M, QI-O and QI-N have been separated from me-dium pitch, oxidized modified pitch, and thermal polycondensation pitch, respectively. The basic physical properties of three kinds of QIs have been determined by the ultimate analyzer, TGA, particle size analyzer, and polarizing microscope, separately. The microstructure of quinoline insoluble based pitch carbon have been studied by the SEM, XRD, Raman spectrum and the combination of curve-fitted method. The result shown that, QI-M is a kind of submicron carbon sphere with good uniformity. QI-N is a kind of spherical carbon with uniform particle size distribution of about 16 μm. The pyrolisis behavior of three quinoline insolubles is varied. Briefly, both of pyrolysis reaction and condensation reaction have been taken place at the temperature range from 250 ℃ to 500 ℃ for QI-O and QI-N, respectively. However, only pyrolysis reaction has been taken place for QI-M at this temperature range. The contents of graphite crystal (IG/IAll) of quinoline insoluble based pitch carbon (QI-M-C, QI-O-C and QI-N-C) were 10.61%, 6.84%, and 12.43%, respectively. And the contents of disordered carbon (ID3/IAll) were 9.18%, 11.09%, and 6.06%, separately. What’s more, the crystalline sizes (Lc) of each quinoline insoluble based pitch carbons were 1.62 nm, 1.35 nm, and 1.85 nm. QI-N has good graphitization ability, but the graphitization ability of QI-O was poor.
