The kinetics of pyrolysis characteristics of coal tar pitch (CTP) and quinoline soluble of CTP (refined pitch) were investigated by thermogravimetric analysis at the heating rate of 5, 10, 15, 20 /min, respectively. The reaction kinetics parametres were obtained based on Kissinger method, Flynn-Wall-Ozawa method and Friedman method, respectively. The results show that pyrolysis process of CTP and the refined pitch includes three stages. Different heating rate has different effect on carbonization. The pre-exponential factor lnA of CTP and the refined pitch is 14.40 and 12.06, respectively. The reaction mechanism function of CTP and the refined pitch is [-ln(1- )]. The CTP shows more significant temperature sensitivity and higher reactivity than the refined pitch.
