ABSTRACT:
A method of transferring and recovering energy comprises selecting a plurality of two or more different compounds comprising a solid reactant adsorbent and a gaseous reactant adsorbed thereon, each of said compounds having a different gaseous reactant vapor pressure, substantially independent of the concentration of the gaseous reactant, locating a first set of the different compounds in a first reactor and a second set of the different compounds in a second reactor, pressurizing the first reactor at a first pressure and the second reactor at a second pressure, supplying a heat transfer fluid at a first temperature along the first reactor in thermal communication with the first set of compounds, whereby said compounds desorb said gaseous reactant in endothermic reactions, supplying a heat transfer fluid at a second temperature, typically lower than the first temperature, along second reactor in thermal communication with the second set of compounds, whereby the compounds adsorb the gaseous reactant in exothermic reactions, and directing at least a portion of the heat released during the exothermic reactions or a least a portion of heat absorbed during the endothermic reactions to heat exchange means for energy recovery. The invention includes apparatus for carrying out the method.
