Abstract: The kinetics of pyrolysis of large wood samples--up to 27 mm--has been studied by isothermal thermogravimetric analysis. Rate of weight loss can be represented by a first order Arrhenius-type equation, with an activation energy of 125 kJ/mole. The temperature inside the wood sample is given by integration of the Fourier law, in which the thermal diffusivity is temperature- and conversion-dependent. This simple model enables one to predict the time needed to achieve pyrolysis of a large wood sample.
