Ventilated tray for adsorbent desorption

An adsorbent carrier tray for holding adsorbent during a desorption process, said adsorbent carrier tray comprising:

• a housing having four walls, a bottom piece and an open top, said housing being made of a microwave transparent material and having a gas passage formed therein;
• a gas-permeable adsorbent support structure attached to said housing, said adsorbent support structure being spaced above said bottom piece;
• and
• said adsorbent support structure comprising a plate having a plurality of holes formed therein and a plurality of circular members having larger diameters than said holes, each of said plurality of circular members being centered below one of said plurality of holes.
