Abstract:
In this study, an in situ weighting system was used to study the thermal behavior of dried municipal sludge (MS) in the flue gas exiting from calcium‐looping (Ca‐L) process. The results showed that mass loss peak, initial decomposition temperature, and decomposition complete temperature moved to high‐temperature zone with increased heating rate. However, they moved to low‐temperature zone at higher O 2 and CO 2 concentrations. Apparent activation energy ( E ) and preexponential factor ( A ) increased with the increase of heating rate and O 2 concentration and decreased with the increase of CO 2 concentration. The heating rate has the greatest effect on the thermal decomposition of dried MS. With the heating rate increasing, the maximum mass loss peak occurred from 301 to 493°C, the corresponding E and A increased from 36.14 to 45.69 kJ mol −1 and from 29.58 to 321.4 min, respectively. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.
