1. A device for the reversible adsorption of carbon dioxide from a gas mixture, comprising:
- at least one adsorbent vessel comprising one or a plurality of gas permeable cartridge vessels of an inert and dimensionally stable material, and each cartridge comprising a suitable polymeric particular adsorbent having only a primary amino functionality at a total capacity of at least 2.0 eq./l, a surface area (BET) in the range of from 25 to 75 m2/g, and an average pore diameter of 1 to 200 nm; and
further comprising;
a means for desorption of the adsorbed carbon dioxide by pressure, humidity, or temperature adsorption swing, or both;
a means for directing the desorbed gas mixture from the adsorbent cartridges;
a means for the supplying the gas mixture to the cartridges;
a means for recuperation of heat or fluids or heat and fluids, and a desorbed gas mixture;
at least one of;
a means for measuring the carbon dioxide adsorption level, a means for measuring carbon dioxide gas flow rates, and a means for contacting the adsorbent with a warm fluid for inducing desorption of the carbon dioxide; and
an arrangement to subject the cartridges to reduced pressure, and subsequently to contact the cartridges with water having a temperature in the range of from 60°
C. to 100°
C., and a means for separating water or water vapour from the released carbon dioxide for recycling to arrangement.
