Correspondent: XUE Xiang-xin, E-mail: xuexx @ mail. neu. edu. cn) Abstract: A thermogravimetric analysis was made to investigate the pyrolytic properties of the Fushun oil shale and its residue. T he results show ed that their pyrolytic reaction can be divided into tw o processes. The first one is mainly the moisture volatilization w ithin the range from room temperature to 200 , then the moisture volatilization contents in the oil shale and its residue are 2. 446% and 3. 202% , respectively . The second one is mainly the pyrolysis of fixed carbon between 200 and 600 , then the rates of weight loss of oil shale and its residue are 16. 048% and 6. 524% , respectively. And the Coats-Redfern method is used to get the kinetic constant in pyrolytic reaction. Correspondingly, the activation energies of the kerogen shale are 51. 84 and - 1 28. 14 kJ/ mol, and the frequency factors are 62. 35 and 0. 003 25 min , respectively. The activation energies of oil shale residue are 36. 62 and 55. 05
