• A study on zeolite-based adsorbents for CO$_2$ capture

In this study, zeolite-based sorbents were prepared and examined for CO$_2$ adsorption from a simulated flue gas mixture using a fixed-bed flow reactor. Various amines such as monoethanolamine, ethylenediamine, diethylenetriamine and triethylenetetramine (TETA) were impregnated on support materials to prepare the adsorbents. Also, the effects of various parameters on CO$_2$ adsorption capacity have been examined in this work. Further, an effort has been made to characterize various physico-chemical properties like surface area, pore volume, chemical composition, etc. of the in-house developedsorbents. Observation showed that the CO$_2$ adsorption capacity enhanced with amine loading up to a certain concentration. The maximum carbon capture capacity of the 30-TETA-ZSM-5 sorbent is around 53 g of CO$_2$/kg of adsorbent. The thermochemical stability of the adsorbents has been tested by reusing the same material for multiple adsorption–desorption cycles,and no significant change in CO$_2$ adsorption capacities was observed.
