The influence of calorimetric parameters on estimation of kinetic parameters by TG is considered. A numerical model is used to highlight the correlation displayed by the parameters themselves and the possibility of representing kinetic parameters as a linear combination of variables, describing heat transfer contributions, is examined. Simulations, using the previously determined kinetic parameters for calcium oxalate dehydration, show the limitations of such an approach, even though interesting observations are derived. The previously reported iterative method for kinetic parameters calculation therefore should not be replaced by a general linear combination.

Abstract
The influence of calorimetric parameters on estimation of kinetic parameters by TG is considered. A numerical model is used to highlight the correlation displayed by the parameters themselves and the possibility of representing kinetic parameters as a linear combination of variables, describing heat transfer contributions, is examined. Simulations, using the previously determined kinetic parameters for calcium oxalate dehydration, show the limitations of such an approach, even though interesting observations are derived. The previously reported iterative method for kinetic parameters calculation therefore should not be replaced by a general linear combination.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
