“…In pomegranate peel dry powder, the low moisture content (5.448%) indicated that the biomass is suitable for pyrolysis and has low water storage capacity. On the other hand, the high content of volatile matter (72.922%) indicated that a considerable amount of condensable vapor content and permanent gasses are present in biomass and can produce an excess amount of syngas and bio‐oils, our results are in great agreement with previous studies 5,7,30,36 . Furthermore, the high VM content shows that the present biomass is a bioenergy crop.…”

“…A much higher HHV of pomegranate peel as compared to other biomasses such as Aesculus indica (15.97 MJ kg −1 ), tetraselmis sp. (16.39 MJ kg −1 ), solid later waste (14.15 MJ kg −1 ), food waste (15.0 MJ kg −1 ), WCS (11.91 MJ kg −1 ) and cotton waste (17.5 MJ kg −1 ) further speculate that pomegranate peels have high bioenergy potential 5–7,37–39 …”

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.

“…Taking ln (−𝑑𝑚/𝑚𝑑𝑡) and 1/𝑅𝑇 be obtained by plotting as the ordinate and abscissa, and the slope of the straight line is the intrinsic activation energy of soot oxidation reaction [8]. Therefore, we can obtain the variation curve of soot particle activation energy with -100 / RT through section by section analysis, as shown in figure 7.…”

the soot oxidation characteristics and oxidation mechanism of ethylene flame with different methane mixing ratios were studied by thermogravimetric analyzer and oxidation reaction kinetics analysis. The conclusions are as follows: in the process of programmed temperature rise, there is almost no loss in the quality of soot particles below 450 °C; With the increasing temperature, the mass of soot particles began to decrease when the temperature exceeded 500 °C; When the temperature exceeds 750 °C, the mass of soot particles is close to zero; With the increase of flame height, the thermogravimetric curve of soot first shifts to high temperature and then to low temperature; The activation energy of soot is closely related to its oxidation process, and decreases first and then increases with the deepening of soot oxidation; The mixing of methane promotes the rise of soot ignition temperature and burnout temperature, and the minimum activation energy of soot decreases at low flame height and increases at high flame height.
