Abstract
An improved apparatus for staging solid-vapor complex compounds comprises heat exchange means for transferring heat from super-heated refrigerant vapor from a desorbing reactor to cooled refrigerant vapor directed to an adsorbing reactor. In another embodiment a liquid subcooler is used to cool liquid refrigerant passing from a condenser to an evaporator with cold refrigerant gas directed to an adsorbing reactor from the evaporator.

9. A process for staging solid-vapor compounds comprising:
-
alternately adsorbing and desorbing a gaseous reactant from first and second reactors, respectively, each reactor containing a plurality of two or more different compounds comprising a solid reactant and a gaseous reactant adsorbed thereon or desorbed therefrom, wherein each of said compounds has a different gaseous reactant vapor pressure, substantially independent of the concentration of gaseous reactant, said compounds arranged in successive order of gaseous reactant vapor pressure, supplying a heat transfer fluid at a first temperature along one of said reactors in successive thermal communication with said first set of compounds resulting in a first pressure, whereby said compounds desorb said gaseous reactant in endothermic reactions, and directing desorbed gaseous reactant from the desorbing reactor to a condenser, supplying a heat transfer fluid at a second temperature, lower than said first temperature, along the other of said reactors in successive thermal communication with said second set of compounds, directing gaseous reactant from an evaporator to said other reactor, and operating said other reactor at a second pressure whereby said compounds therein adsorb said gaseous reactant in exothermic reactions, and directing a liquid flow of condensed gaseous reactant from said condenser to said evaporator and concurrently directing a gaseous flow of gaseous reactant from said evaporator to said adsorbing reactor through a heat exchanger and exchanging heat between said liquid stream and said gaseous stream.
