ABSTRACT:
A ventilated tray for holding adsorbent material during microwave desorption of the material. The tray facilitates the flow of desorption gases through a bed of adsorbent without agitation of the adsorbent. The ventilated tray includes a housing having four walls and a bottom piece and a gas-permeable adsorbent support structure disposed in the housing. The adsorbent support structure is positioned above the bottom piece so that the adsorbent support structure, the bottom piece and the four walls define a plenum. A gas passage aperture is located in one of the housing walls to providing fluid communication between the plenum and the exterior of the housing. The adsorbent support structure is a porous plate having pores which are smaller than the grain size of the adsorbent material. Alternatively, the adsorbent support structure can be a two-tiered structure which relies on the adsorbent's angle of repose to support the adsorbent. A second embodiment of the ventilated tray includes a housing having four walls and a gas-permeable bottom piece which supports the adsorbent bed.
