Assessment of pyrolysis-kinetics of corncob and eucalyptus biomass residue using thermo gravimetric analysis

Agriculture and forest residues have a large energy potential and there are eligible to become sustainable promising energy resources in future. Present study deals with the analysis of thermo-physical properties, Fourier transform infrared spectroscopy (FTIR), and kinetics of corncob and eucalypts. The pyrolysis, Combustion characteristics and Kinetic deconvolution of biomass have been evaluated by thermo-gravimetric analyser from atmospheric temperature to 1100°C at a heating rate of 10°C/min. The kinetic analysis of biomass was determined by Flynn-Wall-Ozawa (FWO) methods. From the results, the average activation energies of corncob and eucalyptus were found as 91.29 and 77.21 kJ/mol respectively. The results showed that corncob was sensitive to rate of heating due to lower lignin content.
