Curbing the greenhouse effect by carbon dioxide adsorption with Zeolite 13X

The removal of carbon dioxide (CO₂) from industrial emissions has become essential in the fight against climate change. In this study, we employed Zeolite 13X for the capture and recovery of CO₂ in a flow through system where the adsorbent was subjected to five adsorption-desorption cycles. The infl...

Description
Summary:The removal of carbon dioxide (CO₂) from industrial emissions has become essential in the fight against climate change. In this study, we employed Zeolite 13X for the capture and recovery of CO₂ in a flow through system where the adsorbent was subjected to five adsorption-desorption cycles. The influent stream contained 1.5% CO₂ at standard conditions. The adsorbent bed was 1 in. in length and 1 in. 3/8 in dia., and was packed with 10 g of the zeolite. Temperature swing adsorption (TSA) was employed as the regeneration method through heating to approximately 135 °C with helium as the purge gas. The adsorbent capacity at 90% saturation was found to decrease from 78 to 60gCO₂/kgZeolite₁₃X after the fifth cycle. The CO₂ capture ratio or the mass of CO₂ adsorbed to the total mass that entered the system decreased from 63% to only 61% after the fifth cycle. The CO₂ recovery efficiency ranged from 82 to 93% during desorption, and the CO₂ relative recovery, i.e., CO₂ desorbed for the nth cycle to CO₂ adsorbed for the first cycle, ranged from 88 to 68%. The service life of the adsorbent was determined to be equal to eleven cycles at a useful capacity of 40gCO₂/kgZeolite₁₃X. © 2007 American Institute of Chemical Engineers AIChE J, 2007
