Abstract

The ZSM-5-type zeolites were prepared using three types of structure directing agent to investigate the effect of pore structure and PEI impregnation on the CO<inf>2</inf> adsorption capacity. The CO<inf>2</inf> capacity was primarily affected by the number of the adsorption site and the volume for trapping CO<inf>2</inf>. CO<inf>2</inf> was well adsorbed inside the micropore with stronger electric field. The CO<inf>2</inf> capacity increased with increasing amounts of impregnated PEI until PEI loading exceeded the total pore volume, because PEI predominantly occupied the pores of ZSM-5. The ZSM-5 with large surface area and total pore volume was the most favorable for amine-impregnated ZSM-5.
