Methods for Determining the Kinetic Parameters from Nonisothermal Thermogravimetry: A Comparison of Reliability

Abstract

This paper has presented some popular methods used to determine the kinetic parameters from nonisothermal thermogravimetric analysis (TGA) data. These methods include the improved Doyle–Ozawa method, and the nonlinear regression method. The above-mentioned methods along with a new method proposed by the present authors are compared with the true thermogravimetric data generated by the synthetic TG/DTG curves. This paper has shown that the proposed E₂-function method has the advantages of both reliability in calculation and straightforwardness in formulation.
