Abstract
Mesoporous carbon (MC) impregnated with Triethylenetetramine (TETA) was developed as carbon dioxide (CO2) capture material to increase the adsorption ability and selectivity towards carbon dioxide. MC was chosen as it has a larger surface area to accommodate a large number of amines compared to the commercial activated carbon, which mainly consists of micropores. The carbon dioxide capture performance of mesoporous carbon impregnated with TETA (MC-TETA) was evaluated by comparing it with commercially available activated carbon and zeolite, which were also impregnated with TETA. Based on the CO2 adsorption performance results, it can be understood that the appropriate TETA helped to improve the adsorption ability compared to the unmodified MC. Meanwhile, amine impregnation of zeolite reduced the adsorption ability compared with its unmodified form. Therefore, it can be concluded that MC-TETA is the most suitable material for amine impregnation due to its large pore size, which attributes to better accommodate large numbers of amines.
