The non-isothermal kinetics for mesophase transformation of Baogang-I coal tar pitch (I-CTP), soft pitch consisted of I-CTP and 18% phenanthrene residue oil (PRO) or I-CTP and 30% PRO have been studied in a thermal conversion unit Kinetic parameters were calculated by using an integral method Results showed that the process of mesophase pitch transformation could be described in first order reaction The activation energy of I-CTP is 17536*#kJ/mol But adding 30% PRO, which improved the reactivity of I-CTP with activation energy is 13807*#kJ/mol, is not beneficial to mesophase
