### Pyrosis Analysis of CPHs  
The temperature-dependent behavior of pyrolysis was analyzed within the range of 500 \({}^{\circ}\)C to 700 \({}^{\circ}\)C. The primary observation was a shift in the yield of solid, liquid, and gas fractions. Other operational parameters were kept constant to ensure that only the temperature was varied. The experiments were conducted under identical conditions regarding carrier gas flow rate and residence time. All pyrolysis experiments were performed in triplicate at 500 \({}^{\circ}\)C, 600 \({}^{\circ}\)C, and 700 \({}^{\circ}\)C to ensure result reproducibility. The pyrolysis experiments demonstrated high repeatability, as evidenced by the low standard deviations observed across replicates. The mean values of gas yields varied consistently with temperature: 24.91% at 500 \({}^{\circ}\)C, 26.74% at 600 \({}^{\circ}\)C, and 32.94% at 700 \({}^{\circ}\)C, with standard deviations of \(\pm\)0.29%, \(\pm\)0.34%, and \(\pm\)0.41%, respectively. These results confirm that the process is highly reproducible under controlled conditions. Additionally, the increase in syngas production at higher temperatures suggests that pyrolysis can be optimized for improved energy recovery, supporting its feasibility for industrial applications. Table 5 presents the mean values along with standard deviations for the product yields and gas composition. Statistical analysis confirmed that temperature had a significant effect on gas yield, which increased from 24.91% at 500 \({}^{\circ}\)C to 32.94% at 700 \({}^{\circ}\)C, with a standard deviation of \(\pm\)0.29%. The yields of the fractions obtained in these pyrolysis experiments, where temperature was varied, are shown in Table 5. The HHV values presented in the table refer to the carbon-fixed solid of the biomass and are given for both dry and wet conditions. The yield distribution and gas composition measurements were repeated three times for each temperature condition (500 \({}^{\circ}\)C, 600 \({}^{\circ}\)C, and 700 \({}^{\circ}\)C), and the values reported in Table 5 represent the mean results of these triplicate experiments. \begin{table}

Table 5: Influence of pyrolysis temperature on the yield of fractions, immediate analysis, and PCS. A one-way ANOVA test confirmed that the differences in gas yield across temperatures were statistically significant (\(p\) < 0.05), indicating that temperature had a substantial effect on product distribution. As shown, there is a decrease in the solid fraction and an increase in the gaseous fraction, which becomes more pronounced starting at 600 \({}^{\circ}\)C. This is due to the thermal cracking of the liquid fraction, which leads to a reduced yield of the liquid phase at higher temperatures. This behavior has been observed in previous studies on the decomposition of agricultural and forestry residues, such as those by [PERSON] et al. (1996, 2000) and [PERSON] et al. (2003, 2005, 2009) [48; 49; 50]. In our pyrolysis experiments involving cocoa pod husks (CPHs) at temperatures of 500 \({}^{\circ}\)C, 600 \({}^{\circ}\)C, and 700 \({}^{\circ}\)C, gas yields of 24.92%, 26.73%, and 32.92% were observed, respectively.
