摘要：
Kinetic triplets and thermodynamic parameters of the pyrolysis of Putranjiva roxburghii (PR) and Cassia fistula (CF) non-edible oilseeds were studied using thermogravimetric analyzer. The kinetic parameters were assessed using both model-free [Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (OFW), Starink (STR), Li and Tang (LTA), Friedman (FRM), Vyazovkin (VYZ), Kissinger (KN), Avrami (AVM), and Master plot (MP)] and model-fitting [Coats-Redfern (CR)] methods at four different heating rates (10, 25, 40, and 55 degrees C/min) somewhere in the range of 10% and 80% conversions. The reaction mechanisms were found to be in good agreement with the experimental thermal analysis data. Thermodynamic parameters (Delta G, Delta H, and Delta S) are also determined by model-free isoconversional method. The kinetic and thermodynamic parameters recommended the appropriateness of PR and CF non-edible oilseeds for pyrolysis process. (C) 2020 Elsevier Ltd. All rights reserved.
