A kinetic study and thermal decomposition characteristics of palm kernel shell using model-fitting and model-free methods

The thermal decomposition behaviours of palm kernel shells (PKS) under non-isothermal conditions were investigated using the thermogravimetric analyser. A comparison of model-free and model-fitting methods for PKS decomposition was performed. Differential and integral methods used showed an increase...
