Patent ID: 7517396

Claim:
An apparatus for selectively adsorbing gas during adsorption processes and desorbing gas during desorption processes, comprising: a tube comprising: a porous sidewall having a first end and an opposite second end; a first end-fitting connected to said first end, wherein said first end is sealingly closed by said first end fitting; and a second end-fitting connected to said second end, wherein said second end is sealingly closed by said second end fitting; and a particulate porous gas storage material located within said tube, wherein said material cross-sectionally spans said tube; wherein said material is selected from the group consisting of: metal organic frameworks, nanocubes, coordination polymers, prussian blue analogues, and polymers having intrinsic microporosity; wherein the porosity of said sidewall is predetermined to prevent said material from passing threrethrough; and wherein the porosity of the sidewall is further predetermined to allow, during adsorption processes, gas to pass through said sidewall and be adsorbed by said material, and, during desorption processes, to allow gas desorbed from the material to pass out through said sidewall.
