چکیده انگلیسی
Two-stage decomposition of cotton is used as an experimental example. The only curve of the perturbations measured at one heating rate is used for calculating the kinetic constants. This curve contains information about mass loss in the hidden form. Nevertheless, one can ensure that the used mathematical models with the obtained kinetic constants are able to approximate not only the curve of mass loss subjected to the handling but also a curve measured at another heating rate. The high predictive force of modulated thermal analysis promises to be an obvious alternative to the classical technique. The weak sensitivity of predictions made by modulated thermogravimetry to a form of models used is a very important distinction for the wide application of this analysis in different fields of chemical engineering.
