The Influence of Precursor Moisture Content on the Pore Development and Breakthrough Kinetics of Periwinkle and Coconut Activated Carbon Using Aspen V11
Abstract
The production of activated carbon from biomass based is known for their pore volume as they are characterized by a high specific surface area which serves for several purposes including air and water purification, gas separation, energy storage etc. therefore this research aimed at investigating the influence of precursor moisture content on the pore development and breakthrough kinetics of periwinkle and coconut activated carbon using aspen V11 for carbon dioxide (CO2) and carbon monoxide (CO) on the determination of the influence of precursor moisture content on the pore development and breakthrough kinetics of periwinkle and coconut activated carbon for carbon dioxide (CO2) and carbon monoxide (CO) using proximate analysis. The results show that coconut precursor yielded higher moisture content (14%) over periwinkle precursor yield (7%) after heating at 105 °C for 24 hours. The data was integrated into the material synthesis phase, where the carbonization temperature was maintained at 500 °C and the impact of these physical properties on gas flow resistance and adsorption kinetics was then simulated using the Ergun Equation and Linear Driving Force models within the Aspen V11 to determine the breakthrough profiles for CO2 and CO adsorption. The 7% lower moisture content from the periwinkle adsorbent show its influences on the pore development of activated carbon and breakthrough kinetics in simulation process as it exhibits moderate run over coconut with sharp run. And the periwinkle adsorbent also shows high affinity for CO2 over CO as compared to coconut adsorbent, while CO shows inverse selectivity for both adsorbent runs.
