ABSTRACT:
A method of transferring and recovering energy comprises placing in different reactors two or more different solid adsorbents having a gaseous reactant adsorbed thereon and each having a different gaseous reactant vapor pressure, in a first reaction cycle, pressurizing a first portion of the reactors at a first pressure to desorb the gaseous reactant in an endothermic reaction, and pressurizing a second portion of the reactors at a second pressure to adsorb the gaseous reactant in an exothermic reaction, and in a second reaction cycle, pressurizing the first portion of the reactors at the second pressure to adsorb the gaseous reactant in an exothermic reaction, and pressurizing the second portion of the reactors at the first pressure to desorb the gaseous reactant in an endothermic reaction, and directing at least a portion of the heat released during the exothermic reactions or at least a portion of heat adsorbed during the endothermic reactions to heat exchange means for energy recovery.
The invention includes apparatus having means for carrying out the process.
