| description | In this work, the physiochemical characteristics, thermodynamics, and sustainability of the pyrolysis of Sesamum indicum biomass were assessed. The pyrolysis kinetics of sesame agro-residues performed using isoconversional techniques such as Kissinger, KAS, and OFW methods showed activation energies of 192, 120, and 123 kJ mol ^−1 , respectively. The impact of the pyrolysis temperature (550, 650, 750 °C) on the generation of biochar, bio-oil, and gas is also studied; the exergy efficiency increased from 82.7 at 550 °C to 87.3% at 750 °C with an increase in the temperature. Sesame biochar’s Van Krevalan diagram showed how its fuel-like characteristics also grew with rising temperatures. The input and output parameters showed a high agreement in the mass, energy, and exergy balance closures. However, it was shown that the overall energy efficiency was greater at 750 °C (71.2%) compared to 55.5% and 69.8% at 550 °C and 650 °C, respectively. Sustainability analysis showed that lower temperatures had a smaller impact on the environment. |
