“…ΔG estimated from the model-free kinetic model is varied a little throughout reaction as seen in Table 2. This trend is linked to the occurrence of non-spontaneous reactions and shows that surplus energy is available at the end of the process [24]. The model fitting CR method concluded the same ΔG (≈163 kJ/mol) as calculated through model-free methods as shown in Table S1 corresponding to 10 ℃/min.…”

“…The regression results of E a , pre-exponential factor, and thermodynamic parameters, based on each model type are given in Table S(1), which were further analyzed by Criado master plot method for validation. It is observed that the method of CR at different heating rates does not substantially change the value of the activation energy [24,46,47]. Table S(1) describes the order-based reaction mechanism (F 1 and F 2 ), controlling area (R 2 ), and 2-diffusion reaction models are the most probable reaction mechanism explaining the solid-state reaction during pyrolysis of FNB based on Fig.…”

“…Based on elemental analysis, FNB has molecular formula CH 1.404, O0.8725, N 0.155 S 0.123 which is significant in predicting the expected pyrolytic products. The average HHV (13.8 MJ/Kg) of FNB is higher than corn stover (10.7 MJ/Kg), sawdust (10.4 MJ/ Kg), switch grass (12.6 MJ/kg) [23], sugarcane bagasse (12.2 MJ/kg) [24], and original coal (10.6 MJ/kg) [22], rendering it a potential candidate for the production of bioenergy. Further, Fourier-Transform Infrared (FTIR) spectrum is used to identify the functional groups in the FNB as shown in Fig.…”

“…Therefore, IR transmittance for -OH (3100 cm −1 to 3600 cm −1 ), C-H (2800 cm −1 to 3000 cm −1 ), and C = O (1760 cm −1 ) identifies the presence of cellulose content. The C = O stretch for ketones/aldehydes indicates 1 [24]. Peaks below 1000 cm −1 belong to skeleton vibrations that is why it is difficult to interpret them individually.…”

The over reliance on fossil fuels for power generation has resulted in an alarming depletion of petrochemical crude oil reserves, that also is the cause of elevated greenhouse gas effects. Biomass resources are considered potential fuels for the future on account of their renewable and carbon-neutral features. This study presents the physicochemical characteristics and pyrolysis behavior of a novel biomass Ficus natalensis barkcloth (FNB). Physicochemical characterization indicated that the FNB has 74.4% volatile matter contents, a higher heating value (HHV) of 13.8 MJ/kg, and it has 67% cellulose as its main chemical constituent. Thermogravimetric analysis (TGA) showed that major decomposition occurred at the core devolatization (235℃ to 410 ℃) under inert thermal degradation. Model-free and model-fitting kinetic methods were applied to TGA data to compute the kinetics triplet for FNB biomass. The average activation energy (E a ) of the FNB pyrolysis process was determined to be 168 kJ/mol. The compensation effects between pre-exponential factor (A) and E a detected a rise in collision intensity for the pyrolysis of FNB at high heating rates. The Criado master plot results showed that the pyrolysis of FNB followed first-order reaction (F 1 ) mechanism. The thermodynamic parameters, such as change in enthalpy (ΔH), Gibbs free energy (ΔG), and entropy (ΔS), were also calculated and compared with kinetics parameters to evaluate the evolution of thermal degradation. Physiochemical and thermo-kinetic analysis of FBN revealed its comparable bioenergy potential with established biomasses.

The burning of agricultural residue in open fields poses a serious environmental threat that adversely affects human health and the ecosystem. Overall, this study aims to quantify emissions because of stubble burning followed by pyrolysis conversion of this feedstock and finally evaluate its energy performance. An assessment about pollutant emissions because of open-field burning was made, considering the two scenarios of flaming and smoldering. The inventory includes gaseous pollutants, particulate matter, and greenhouse gases with a total average of 7 TPA emissions per hectare of cultivated land. Subsequently, pyrolysis was carried out in a fixed bed semi-continuous lab-scale setup. The heating value of 18.85, 28.13, and 3.15 MJ kg–1 was obtained for 36.02, 25.20, and 38.78 wt % yield of bio-oil, biochar, and fuel gas, respectively. Further analysis also indicates phenols, aldehyde, alcohols, and other organic fractions in bio-oil of density 1.06 g cm–3 and 34.63 cm2 s–1 kinematic viscosity. This study’s significant highlight is a detailed analysis of energy gain from the process in terms of various performance indices. The net energy balance was applied to each co-product. The biochar was evaluated as the most energy valuable pyrolysis product with 0.985 MJ input/MJ output index and 72.35% energy efficiency. The fossil-to-energy ratio was determined as 1.28, indicating a net positive energy gain for the system’s input resources. Altogether, these results establish the viability of this sustainable waste-to-energy process as an alternative to conventional fossil fuels and encourage its commercial upscaling.
