Adsorption of a Non-Woven Fabric with Activated Carbon for CO₂

Abstract:

The adsorption of CO2 on a non-woven fabric with activated carbon before and after dipping treatment has been studied. It has been found that dipping treatment with Na2CO3 and KOH can improve the adsorption of CO2 on the non-woven fabric. KOH is a better dipping agent than Na2CO3. High temperature is beneficial to the adsorption of CO2 on the fabric dipped with KOH. With increasing relative humidity, the adsorption efficiency is decreased for both original fabric and that dipped with KOH. Increasing adsorption layer number can improve adsorption efficiency. However, when the number of adsorption layers exceeds 3 the increased amplitude of adsorption efficiency is obviously reduced, while the pressure loss of the system is remarkably increased.
