4.3. Devolatilization temperature
Devolatilization temperature is characterized as the local temperature where the maximum rate of devolatilization appears throughout the particle at any given time (see Fig. 7). It is important information because we assume that the devolatilization temperature remains constant regardless the location of reaction front in the SCM. Fig. 8 shows the devolatilization temperature at various overall conversions obtained from the detailed particle simulation. It stayed almost constant temperature throughout the conversion, showing prothallus constant devolatilization temperature is a reasonable assumption. Therefore, method for the estimation of devolatilization temperature is necessary for the application of the SCM. Several methods were found in the literature  and . However, no method gave reasonable values compared with the devolatilization temperature of detailed particle simulation (Fig. 8).
