Abstract
A thermochemical system and process for producing heat and/or cold by solid-gas chemical reaction is disclosed. The system and process utilizes a reactant formed of a compressed support and at least two salts which are distributed throughout the compressed support, the salts being active towards a gas. The salts of the reactant are selected for the system and process so that in the system and process one salt will react with the gas in the reactor while the other salts in the reactant remain substantially unreacted to produce heat or cold at a first temperature or power level and, thereafter, one of the other salts of the reactant reacts with the gas to produce heat or cold at a second temperature or power level which is different from the first temperature or power level.
