Abstract
A process and apparatus for multi-stage sorption and desorption of process gas using a multiple concentric tube apparatus having a thermal supply gas pass through the central conduit creating a thermal wave passing through a high temperature sorption/desorption salt in the innermost annular compartment desorbing prior sorbed process gas followed by passing the thermal wave to an outer annular compartment which together with heat of sorption of process gas in an inner annular compartment desorbs process gas in the outer annular compartment. The process is useful in heat pumps and gas evaporative cooling cycles.
