Abstract

<jats:title>Abstract</jats:title> <jats:p>The carbon dioxide adsorption properties of zeolite Rho materials, containing various exchangeable cations have been investigated. All carbon dioxide adsorption properties were measured at a temperature of 25 °C over a pressure range of 0–100 kPa. The results show that the carbon adsorption properties are dependent on the cations present. The highest amount of CO2 absorbed, measured at 4.0 mmol g−1, was obtained for a proton-exchanged zeolite Rho (HRho), which was prepared by the calcination of NH4+-exchanged zeolite Rho at 350 °C.</jats:p>
