The evaluation of kinetic parameters from thermogravimetric curves is considered for two linear transformations of the rate expression for various decomposition models. The differentials are calculated by applying splines to theoretically calculated curves for ten decomposition models and to an experimental curve for the decomposition of magnesite. The sensitivity of the values of the kinetic parameters with decomposition model obtained for the two treatments are investigated and, in the case of the experimental data, compared with values obtained for the integral treatment of the rate equation. |
