Pyrolysis, kinetics analysis, thermodynamics parameters and reaction mechanism of Typha latifolia to evaluate its bioenergy potential

Abstract This work was focused on understanding the pyrolysis of Typha latifolia . Kinetics, thermodynamics parameters and pyrolysis reaction mechanism were studied using thermogravimetric data. Based on activation energies and conversion points, two regions of pyrolysis were established. Region-I occurred between the conversion rate 0.1–0.4 with peak temperatures 538 K, 555 K, 556 K at the heating rates of 10 K min −1 , 30 K min −1 , and 50 K min −1 , respectively. Similarly, the Region-II occurred between 0.4 and 0.8 with peak temperatures of 606 K, 621 K, 623 K at same heating rates. The best model was diffusion mechanism in Region-I. In Region-II, the reaction order was shown to be 2nd and 3rd. The values of activation energy calculated using FWO and KAS methods (134–204 kJ mol −1 ) remained same in both regions reflecting that the best reaction mechanism was predicted. Kinetics and thermodynamic parameters including E , Δ H , Δ S , Δ G shown that T. latifolia biomass is a remarkable feedstock for bioenergy.
