The pyrolysis reactions of Maoming oil shale were investigated by thermo gravimetric analyzer with linear heating rate 6.8 K/min; particle size of samples 0.075mm( -200mesh); thickness ot sample layer 0.6mm; flow of inert stream (nit rogen) 100ml/min. The thermogravimetric curve, the relationship of rate of weight loss versus temperature as well as that of conversion versus temperature were obtained. The kinetics treatment of pyrolysis data showed that the pyrolysis reactions of Maoming oil shale can be well described by three kinetic equations of first order reaction in three different temperature regions. The pyrolysis kinetics parameters of oil shale, i. e. the apparent activation energy E, the pre-exponential factor A and the corresponding expressions of rate constants for pyrolysis reactions were found by least square curve fitting of pyrolysis data.
