Development of CO₂ Adsorbent on Anodic Alumite for Ethanol Steam Reforming

Abstract

CO₂ adsorbent on anodic alumite for ethanol steam reforming was prepared by a dip-coating method. CO₂ adsorption amount increased with the number of times the dip-coating was performed. The best results were obtained when the dip-coating was done more than 4 times, whereupon the adsorption amount increased drastically. Performance of the CO₂ adsorbent at different temperatures was monitored and recorded. Also, cyclic adsorption–desorption on the selected sample was performed, the result of which shows that desorption at a lower temperature is preferred. The sample also exhibited excellent endurance.
