Patent ID: 7074386

Claim:
A method of capturing specified materials, wherein the specified materials are atoms, molecules, ions or a combination thereof, the method comprising: a) contacting a microporous material, capable of undergoing a temporary structural distortion which alters resting lattice dimensions under increased ambient pressure and at least partially returning to rest lattice dimensions when returned to ambient pressure, with a hydrostatic fluid having at least one specified material carried therein, under pressure which structurally distorts said lattice sufficiently to permit entry of said at least one specified material, wherein the microporous material is a Zn-containing form of Linde A zeolite having the molecular structure Zn 6 [Al 12 Si 12 O 48 ] 29H 2 O; and b) reducing pressure of said fluid to permit return to at least partial resting lattice dimension while said at least one specified material is therein; whereby said at least one specified material is captured in said microporous material to form a modified microporous material.
