Carbon dioxide is a major contributor in greenhouse gases. Unswerving increase of CO 2 in atmosphere, due to growing industries and automobile field, is a wakeup call to the world as excess of CO 2 will affect humans in many ways among which greenhouse effect dominated the most. In the present work potassium based zeolite‐F was synthesized by hydrothermal method as reported by International Zeolite Association. Synthesized zeolite‐F was characterized with powder X‐Ray diffraction analysis, FT‐IR spectroscopy, scanning electron microscopy, thermo gravimetric analysis and BET surface area measurement. The equilibrium adsorption capacities of pure gases CO 2 , N 2 , and CH 4 were measured at 273, 288, and 303 K up to 850 mmHg. Although zeolite‐F possesses low CO 2 adsorption capacity (43.6cc/g) at 303 K, the selectivity towards N 2 and CH 4 reflects its potential as an efficient CO 2 adsorbent. The selectivity of CO 2 over N 2 in zeolite‐F was 38 at 303 K and 850 mmHg pressure, whereas selectivity for CO 2 over CH 4 was 30. Thus, zeolite‐F has shown potential for selective CO 2 adsorption from its gas mixture with N 2 and CH 4 . © 2017 American Institute of Chemical Engineers Environ Prog, 36: 850–856, 2017
