Microporous Coordination Polymers as Efficient Sorbentsfor Air Dehumidification.

Airdrying is a widespread and critical industrial process. Removalof water from air is commonly accomplished by passage through a desiccantsuch as alumina; modestwater capacity and energy intensive regeneration are limitations ofcurrently used sorbents. Microporous coordination polymers (MCPs)are demonstrated here to be efficient desiccants for the dehumidificationof air, and a comparison of their capacity, regenerability, and efficiencywith commercial activated alumina is conducted. Complete regenerationusing dry air with mild heating is achieved. The attainment of highcapacity for the adsorption of water coupled to facile regenerationindicates that gas dehumidification may be an important applicationfor MCPs. [ABSTRACT FROM AUTHOR]
