Abstract
Methods for forming adsorbent laminate structures particularly for use in pressure swing adsorption processes and devices are disclosed. One disclosed embodiment comprises providing a metal or alloy support and depositing adsorbent material onto the support by electrophoretic deposition. Adsorbent material also may be deposited on plural strips, which are then assembled into a laminate structure along the support. Adsorbers also are described comprising first and second wire mesh sheets having adsorbent material deposited on a first major planar surface thereof. The first and second sheets are placed adjacent one another and spaced sufficiently to define a flow channel. Another disclosed embodiment comprises plural wire mesh sheets having adsorbent material deposited on both first and second major opposed planar surfaces thereof, the sheets being spaced from each other to define a gas flow channel. The adsorber may include ventilation gaps to provide ventilation between flow channels.
