摘要:
In various aspects, apparatuses and methods are provided for low pressure drop gas separations. In PSA processes, where there are large swings in pressure and corresponding swings in fluid velocity through the adsorbent, mechanical stresses during pressure cycling are of considerable concern. When that pressure is relieved in a lower pressure portion of the cycle, the high velocity of gas moving through the adsorbent bed can erode, strip away, or otherwise damage the channels within the adsorbent. Provided herein are methods which utilize flexible boundaries between adsorbent beds that are operated out of phase with one another. The flexible boundaries permit an increase in void space through the adsorbent during high pressure stages of the cycle and a decrease in void space through the adsorbent during low pressure stages of the cycle.

A method for preparing a metal-organic framework (MOF) comprising contacting one or more of a rare earth metal ion component with one or more of a tetratopic ligand component, sufficient to form a rare earth-based MOF for controlling moisture in an environment. A method of moisture control in an environment comprising adsorbing and/or desorbing water vapor in an environment using a MOF, the MOF including one or more of a rare earth metal ion component and one or more of a tetratopic ligand component. A method of controlling moisture in an environment comprising sensing the relative humidity in the environment comprising a MOF; and adsorbing water vapor on the MOF if the relative humidity is above a first level, sufficient to control moisture in an environment. The examples relate to a MOF created from 1,2,4,5-Tetrakis(4-carboxyphenyl )benzene (BTEB) as tetratopic ligand, 2-fluorobenzoic acid and Y(NO3)3, Tb(NO3)3 and Yb(NO3)3 as rare earth metals.
