Water effect on amine-modification of adsorbents for separation of CO₂/N₂

Abstract

The adsorption of CO₂ can be enhanced through loading amines on adsorbents, therefore, the separation of CO₂ from other gases is promoted. Water plays an important role in this process. Water increases both the adsorption amount of CO₂ and the separation coefficient with N₂ for all amines loaded. However, the effect of loading trialkylamines is not remarkable in the absence of water. The effect of loading dialkylamine does not depend on water, but the adsorbent cannot be regenerated at ambient temperature. In comparison, an adsorbent loading trialkylamine can be regenerated at ambient temperature even in the presence of water with fairly good stability.
