Lattice Structures Coating Concept for Efficient Thermal Linking Beds

Conventional air revitalization technology for removal of CO2, moisture, and trace organic contaminants usually involves a packed bed of sorbent pellets that can be regenerated using a concept similar to that of pressure swing adsorption (PSA). Additional heat input for thermal regeneration is preferred during the adsorption-desorption process to increase the regeneration efficiency. Typically, a pair of adsorber modules consisting of the same sorbent material with identical loading capacity is placed in parallel and work in tandem, where one module adsorbs the contaminants from the process air while the other is in regeneration mode. The two adsorber modules have separate housings and may be placed in separate locations.
