Abstract
A rotary concentrator is provided with homogeneous extruded adsorption blocks. In this way, greater air flow volumes can be processed since the flow passages can be made smaller as can the wall thicknesses. The present invention moves a slurry of adsorbent material, a solvent, and a binder into an extrusion die. The adsorption blocks are then extruded in the die. The blocks are then allowed to dry, and are placed in a rotary adsorption unit. In one embodiment, electrically conducted materials may be included in this slurry. An electric current may be placed on the blocks in the desorb portion of the cycle of the rotary adsorption unit. This heats the blocks, reducing the required volume of desorb gas.
