| contents | <p><span lang="EN-US">In recent years, almonds have become an important fruit crop in Azerbaijan, producing high yields. Almond shells (AS) are an efficient and cost-effective raw material for producing activated carbon (AC) suitable for CO₂ capture. This study examines the effects of carbonization temperature and alkali activation on the porous structure of AC derived from almond shells. Specific surface area (BET), pore volume, pore width, and micropore size distribution were analyzed. Optimal conditions were identified as KOH thermochemical activation with single-stage carbonization at 800–900 °C and carbon/KOH ratios of 1:2 and 1:3. Micropores in the 0.6–0.7 nm range provided high CO₂ adsorption capacity, demonstrating the potential of fruit-processing waste for effective carbon adsorbent production.</span></p> |
