At present, thermal analysis apparatus is used in studying the properties and kinetics of the solid pyrolysis extensively. Basing on a large of experimental figures and applying a formula obtained by Sestak and Berggren [1] : f(α)=α n(1-α) m [-ln (1-α) k, this paper, by means of pressurized thermogravimetric analyzer designed and produced by ourselves, processes the experimental data utilizing the method of nonlinear simulation in several elements, then acquires a reactionary mechanical equation of pressurized coal pyrolysis kinetics, and means the activation energy E or factor ahead of exponential Ko .

Experimental studies on different rank coal pyrolysis were carried out by non-isothermal thermogravimetric analysis. The effects of heating-rate on thermogravimetric curve and the peaked weight loss rate of coal were discussed. The kinetics parameters of coal pyrolysis were determined according to thermo-analysis data. The effects of heating-rate on the kinetics parameters of coal pyrolysis were discussed. The results show that very important information for not only the process of coal gasification and coal liquefaction and coal carbonization but also a basic understanding of coal structure and reactions involving coal pyrolysis can be obtained through thermogravimetric analysis under different heating rate.
