Sažetak
Charcoal yield and quality are influenced by both process parameters and raw material characteristics. In industrial settings, temperature, heating rate, and residence time are typically controlled. However, in rural and traditional production systems, raw material properties—particularly moisture content—become critical for improving efficiency. This study evaluated the effect of initial moisture content (MC) in Prosopis laevigata firewood on charcoal yield and quality. Firewood samples (20×20×20 mm) were conditioned to MC levels of 0%, 20%, 40%, and 60%, and subjected to pyrolysis under laboratory conditions at 450°C for 30 minutes. Firewood and charcoal characteristics were analyzed using one-way ANOVA, Pearson correlation, and linear regression (p<0.05). Results showed that the highest charcoal yield (28%) and density (0.28 gˑcm³) were obtained at 0% MC. Ash content decreased significantly with lower MC, reaching the lowest value (1.58%) at 0% MC. Strong correlations were found between firewood MC and basic density (R²=0.81), charcoal yield (R²=0.87), and energy efficiency (R²=0.65). These findings suggest that reducing firewood moisture content is a simple and effective strategy to improve charcoal yield and quality in traditional production systems.
