“…Moreover, carbonization temperature strongly influences the structure and porosity of residual carbon, as shown in Figure 4a–c, although PP800 has honeycomb‐like porous carbon structures with regular pore distribution. Our results agreed‐well with Saadi et al, who observed a fibrous, rigid vegetal structure of pomegranate peel at 750 and 850°C pyrolysis temperature 30,32 …”

“…Our results agreedwell with Saadi et al, who observed a fibrous, rigid vegetal structure of pomegranate peel at 750 and 850 C pyrolysis temperature. 30,32 BET analysis shows that the specific surface area (SSA) of PP600, PP800, and PP1000 are the 956.98, 1288.97, and 294.16 m 2 g À1 respectively, as shown in Figure 5a and Table 4. PP800 has the highest SSA due to regular pore distribution in residual porous carbon.…”

“…27,29 Although few earlier pyrolysis studies have focused on pomegranate seeds, pulp, and peel, these studies are limited to bio-fuel potential. 28,[30][31][32][33][34] Herein, we have converted the low-cost industrial biomass waste of pomegranate peels through conventional pyrolysis into a possible energy source by thoroughly studying the kinetic and thermodynamic aspects. At the same time, residual char was also characterized and evaluated its potential as activated carbon in the bioenergy sector.…”

Pyrolysis is one of the most common, sustainable, and excellent environmental‐friendly method to evaluate the bio‐energy potential of different types of biomass wastes. Pomegranate peel is a well‐known low‐cost industrial waste. Thus, pomegranate peel's physicochemical properties were explored in detail, and a pyrolysis kinetic study and thermal behavior analysis were performed. Thermal degradation of biomass was investigated on different heating rates (5, 10, 15, and 20°C/min) by using TG‐DSC. To calculate the kinetic parameters (Ea, A), three different kinetic models were used, including the Flynn‐Wall‐Ozawa (FWO), Kissinger‐Akahira‐Sunose (KAS), and Starink methods. The average Ea values for FWO, KAS, and Starink methods are 85.2141, 80.37217, and 80.74315 kJ mol−1, respectively. Furthermore, the reaction mechanism and thermodynamic parameters (ΔH, ΔG, and ΔS) were simulated and calculated to further comprehend the pyrolysis process. The residual carbon (char) obtained after the pyrolysis process was further characterized by SEM‐EDX and BET to quantify the morphology, surface area, and porosity. SEM results revealed that the residual carbon has a honey‐comb like porous structure, whereas BET analysis reflects that PP800 possesses the highest specific surface area (SSA) ~ 1288.97 m2 g−1 with an average pore diameter of 8.85 nm. Thus, it has enormous potential to be used as adsorbent and active electrode material in energy storage devices.

“…Porous electrodes have a substantially higher surface area than conventional electrodes in capacitors, activated carbon has proven excellent properties and can be used in energy storage devices allows them to store much more energy. Activated carbon also enhances the adsorption properties [7,12,13]. To achieve high energy density for such devices, high capacitance materials must be used.…”

Since activated carbon is a highly porous material with a sizable internal surface area, it is simple to adsorb a wide range of substances when used in energy storage devices, sewage treatment, water purification, catalyst, food processing and other applications. This work focuses on the viability of using mixed fruit peels as a precursor for the carbonization process with physical activation to produce activated carbon. The Phase confirmation was examined using X-ray diffraction (XRD). Fourier transform infrared spectrometer (FTIR) concludes the functional groups present in mixed fruit peels activated carbon. Field emission scanning electron microscopy (FESEM) was used to analyze the morphological makeup and textural traits of the activated carbon that was produced. Energy Dispersive X-Ray Analysis (EDX) shows the elemental composition of nano powdered carbon. Raman spectroscopy confirms the presence of graphene that appears at 1580cm-1. Electrochemical Impedance Spectroscopy (EIS) and Nyquist plot in order to evaluate the conductivity performance over the frequency range of 1mHz to 10 kHz, measurements were used. Carbon yield analysis were conducted and analyzed. Wettability of the mixed fruit peels were examined using contact angle. The Mixed Fruit peels activated carbon were subjected to low temperature plasma to increase its surface properties, The outcomes were evaluated, and the charge transfer resistance and the polarization resistance for air plasma treatment is 1.43 and 0.2 ohms. Hydrophilic nature is occurred when treated with air plasma. According to these findings, air plasma treatment of mixed fruit peel activated carbon improves its surface characteristics, making it suitable for electrode in energy storage applications.

“…Pomegranate peel is the main by-product of the industrialization of this fruit, making up approximately 30–40% of the raw material weight. Thus, its disposal represents a great economic and environmental problem for industries, and it explains why there is so much interest in the identification of alternative uses [ 3 , 4 ]. In this sense, pomegranate peel is considered as an ‘eco-friendly’ source of phenolic compounds [ 5 ].…”

Convective drying is the most widely used technique to stabilize by-products in the food industry, permitting later processing. A thorough knowledge of the relationship between moisture content and water activity allows the optimization of not only drying operations, but the settings of storage conditions. Thus, the thermodynamic properties of pomegranate peels were determined during the desorption process. Experimental sorption isotherms at 20, 30, 40 and 50 °C showed type II Brunauer behavior. Eight different theoretical and empirical equations were fitted to the experimental results; the theoretical GAB model and the empirical Peleg model were the ones that achieved the best fit (R2 of 0.9554 and 0.974, respectively). The Clausius–Clapeyron equation and the enthalpy–entropy compensation theory were used to determine the thermodynamic parameters. The isosteric heat determined from the sorption isotherms decreased regularly as the equilibrium moisture content rose (from 8423.9 J/mol at 0.11 kgH2O/kg d.m. to 3837.7 J/mol at 0.2 kgH2O/kg d.m.). A linear compensation was observed between enthalpy and entropy, which indicated an enthalpy-controlled sorption process.
