Development Of Concurrent Activation And Surface Modification (CAM) Process In Palm Kernel Shell-Derived Activated Carbon Production For Post-Combustion Carbon Dioxide (CO2) Adsorption

Palm kernel shell-derived activated carbon (PKSdAC) have been studied for CO2 capture given their unique structure, easy to modify, and low-cost compared to amine-based absorption. This research studies concurrent activation and surface modification (CAM) process to produce PKSdAC using sulphuric acid and barium chloride as activating and doping agents. Parametric optimization of PKSdAC production condition was performed to enhance its porous structure and surface affinity. The optimum CAM-PKSdAC was investigated for its CO2 adsorption performance and stability using customized lab-scale gas adsorption tower against conventional surface modified-activated PKSdAC. Techno-economic feasibility of CAM and two-step activation and surface modification were evaluated.
