Description
|
Modulated temperature or periodic
temperature variation mode. Prediction of the reaction progress
(-) and reaction rate d/dt
(s-1) for an oscillatory temperature mode.
Example 1
DTG, reaction rate d/dt:
Heating rate with and without modulation.
Example 2
DTG, reaction rate d/dt:
Change of underlying heating rate, modulation period and modulation
amplitude.
Example 3
TG, reaction progress
.
Comments:
The kinetic parameters calculated from the non-isothermal
experiments allow prediction of the reaction progress at any
temperature mode: isothermal, non-isothermal and intermediate
intervals in the heating rate, expressed, e.g. in an oscillatory
temperature mode. Examples of predictions of the reaction progress
in an oscillatory temperature mode (widely applied in
temperature-modulated calorimetry) are given above. A
temperature-modulated mode increases the basic understanding of the
characterization of materials in different fields [1-3]. Presented
examples indicate that the prediction of some of the thermal
characteristics under this mode is possible using conventional
non-isothermal experiments.
