Abstract
This study investigated the effectiveness of activated coconut shell as an adsorbent for carbon dioxide (CO₂) capture, with a specific emphasis on the influence of particle size and gas flow rate on the adsorption efficiency. Coconut shells were collected locally from Benin City, Nigeria, and subjected to carbonization at 400°C for one hour, followed by acid activation using 10% hydrochloric acid. The carbonized material was classified into four particle size fractions: >500 μm, 250-500 μm, 100-250 μm, and <100 μm.
