Chabazite and zeolite 13X for CO2 capture under high pressure and moderate temperature conditions

Mesoporous chabazite ion-exchanged with Ca2+ was effective for CO2 capture at 20 bar and 473 K, whereas 13X as a support material enabled recyclable carbonation of ca. 8 wt% Mg(OH)(2) approaching the theoretical maximum for CO2 capture with 10% H2O.
