Abstract
Nine different char samples were tested in thermogravimetric analyzers with continuously rising temperatures and a global one-step kinetic reaction model was used to describe the char combustion. A mathematical method has been presented to deduce the activation energy and pre-exponential factor. The results show that this method has good convergence and is relatively easy for applications. The deduced apparent activation energies and pre-exponential factors will be used for analyzing diffusion effects within char pores in He, Sato, and Chen (2002).
