Patent ID: 7014689

Claim:
A device for separating out a component contained in a gas mixture, the device comprising: a vessel containing at least one bed through which the gas mixture is passed; wherein the at least one bed comprises a plurality of porous, hollow bodies, wherein each of the bodies comprises: a porous shell containing a substance which is suitable for separating out the component contained in the gas mixture; wherein the shell has an external diameter and a thickness, with a ratio of the external diameter to the thickness in the range of from 2:1 to 10:1, and a ratio v 2 /v 1 of between 0.5 and 0.9, wherein v 1 is an achievable increase in mass of the component contained in the gas mixture in mg/g*time until 50% of a maximum separation capacity is reached, and v 2 is an increase in mass of the component contained in the gas mixture in mg/g*time after the 50% of the maximum separation capacity has been reached up to a saturation limit.
