Abstract
The present study is aimed to obtain integral linear method using rational expressions given by Senum and Yang, and a method of selecting the reaction model more quickly and easily and compute the activation energy and pre- exponential factor more accurately was proposed. An improved linear integral procedure coupled with one model-free method and one model-fitting method for the determination of kinetic triplet using non-isothermal data recorded at several heating rates has been suggested. The accuracy and applicability of the obtained values of the kinetic parameters via using non-isothermal techniques is certainly related to accuracy of the integral approximations. Considering the fact that there must be the approximation in the induction of various kinetic methods, we can’t make sure that any specific value is more accurate than the others in the computing results. In order to confirm the accuracy and applicability of research, the suggested method in comparison with often used logical choice method was applied to artificial data following theoretical TG curves for 4-amino-1, 2, 4- triazol-5-one (ATO) and NaHCO 3 . The calculated results using this method for E and A are very close to the true values and also the selected mechanism function completely coincides with the result obtained by using well-known methods, the suggested method offers advantages of accuracy and speed over used method. The results showed that improved method allows for trustworthy estimates of kinetic triplet and this is quite useful in the kinetic analysis. Thus it is considered by an alternative method applicable to the investigation of thermal decomposition kinetics.
