Study on the removal of carbon dioxide by using adsorption-desorption system

Abstract

Ventilation is one of the most common ways to control the carbon dioxide (CO2) concentration of indoor spaces. However, ventilation is not easy when the outdoor air is seriously polluted by particulate matters or gaseous pollutants. In this study, CO2 adsorption-desorption system using chemical and physical adsorbent was investigated. Both chemical and physical adsorbent was used when CO2 concentration was higher, while only physical adsorbent was used when CO2 concentration was lower. Physical adsorbent could be regenerated by thermal desorption. CO2 adsorption-desorption performance of this system in 24 m3 chamber was presented. © 2012 Springer-Verlag Berlin Heidelberg.
