Advanced Studies of Supported Amine Sorbents for CO 2 Removal 2005-01-2943

Supported amines have been shown to absorb CO2 cyclically under temperature swing absorption (TSA) conditions, and show a substantial decrease in desorption energy compared to zeolite materials. Supported amines may therefore be a viable alternative for cyclic capture of CO2 on long-term space missions where minimal energy expenditure is a critical consideration. The research described in this paper presents efforts to improve the TSA-supported amine system with a focus on relationships between important parameters affecting cyclic CO2 capacities, as well as reaction effects of CO2 with the modified amine tetraethylenepentamine.
