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.

“…In the higher temperature range, as well as at the rate of temperature increase, the activation energy was also higher, meaning that the pyrolysis reaction was more difficult to carry out. The activation energy of MS ranged from 42.7 to 47.4 KJ·mol −1 and was dependent on the heating rate, which was significantly lower than that of woody biomass, such as sesame straw and almond shells, indicating that MS biomass was more easily destroyed under warmer temperatures [ 73 ]. The E of PP (107.7 kJ·mol −1 ) is higher than that of MS (42.7 kJ·mol −1 ), corresponding to the experiments that the peak pyrolysis temperature of PP is approximately 70 °C which is higher than the MS.…”

The reuse of biomass waste is conducive to the recovery of resources and can solve the pollution problem caused by incineration and landfill. For this reason, the thermogravimetric analyzer (TGA) was used to study the pyrolysis of the mushroom sticks (MS) and discarded meal boxes at different heating rates (10 °C·min−1, 20 °C·min−1, 30 °C·min−1). The statistical analysis showed that the factors of pyrolysis temperature and particle size had a greater effect, while the heating rate was significant. The TGA revealed that the maximum weight loss rate of the co-pyrolysis of MS and discarded meal boxes increased with the rise of the heating rate, the temperature at which the pyrolysis started and ended increased, and the thermal weight loss displayed a hysteresis phenomenon. By comparing the theoretical heat weight loss curves with the experimental curves, a synergistic effect of the co-pyrolysis process between MS and discarded meal boxes was demonstrated, and the co-pyrolysis process resulted in a reduction in the solid residue content of the products. The Coats-Redfern method was used to fit the pyrolysis process of MS and discarded meal boxes, which applied the first-order kinetic model to describe the main process of pyrolysis and obtained the reaction activation energy between 43 and 45 kJ·mol−1. The results indicated that co-pyrolysis of MS and discarded meal boxes could decrease the activation energy of the reaction, make the reaction easier, promote the degree of pyrolysis reaction, reduce the generation of pollutants, and provide a theoretical basis for the recycling and energy utilization of MS and discarded meal boxes.

Global economic development has a direct link to energy usage. The growth in energy usage implies a rise in gross domestic product (GDP). Crude oil will account for 31.23 percent of global energy consumption in 2020, compared to 6.83 percent for hydroelectricity, 4.30 percent for nuclear, 27.18 percent for coal, and 24.70 percent for natural gas. Crude oil prices climbed sharply and fluctuated in an unpredictable manner, causing the rate of economic growth to fluctuate. In a typical scenario, oil reserves will disappear over the next 40-50 years [1]. In any case, renewable energy is making strenuous efforts to replace fossil fuels and close the energy deficit.
