Abstract

Zinc oxide (5, 10 and 15 wt%) impregnated NaZSM-5 zeolite synthesized using rice husk ash as silica source was tested for $CO_2$ adsorption. The materials were characterized by XRD, SEM-EDS, $CO_2$-TPD and BET techniques. The heat of the reaction (${\Delta}$Hr) derived from DSC for ZnO(10%)/NaZSM-5 was found to be 495 Btu/lb and the maximum $CO_2$ adsorption capacity of ZnO(10%)/NaZSM-5 is 140 mg/g of sorbent. Extraction of silica from the agricultural waste, rice husk and its use in the zeolite synthesis is an added advantage in this study. Hence, from the study it is concluded that zinc oxide impregnated NaZSM-5 could be treated as novel material for $CO_2$ adsorption as they were found to be regenerable, selective and recyclable.
