Abstract

The composition of the studied ash was confirmed by elemental analysis, IR, XRD spectra, and thermal data (TG &
DTA). These analyses were used to determine thermodynamic parameters such as the activation energy (?Ea), enthalpy
change (?H*), entropy change (?S*) and free energy change (?G*) related to the thermal decomposition process were
calculated. Analytical reactions were also used to evaluate the composition of the ash.
