A New Avenue in Ca2+ Ion-Exchanged A-Type Zeolite Chemistry

Caption

A new avenue for selective and excellent CO2-desorption at room temperature and in the lower pressure region by utilizing A-type zeolite; the CO2 molecule adsorbed is simultaneously pinned by two kinds of Ca2+ ions exchanged in respective sites comprising 8- and 6-membered rings flanked side by side as shown in this figure. We have succeeded in separating CO2 from a mixture of gases comprising N2, O2, CO2, and CH4.
