Reagent for thermochemical systems and thermochemical system for using such a reagent

摘要

In a reagent for thermochemical systems, comprising a compressed support and an agent which is active w.r.t. a gas, the active agent consists of salts distributed throughout the support. The support consists of recompressed expanded graphite of density 0.02-0.8. Also claimed is a thermochemical system which produces cold and/or heat by solid-gas chemical reaction and which has a reactor contg. the above reagent, the reactor communicating with a gas-retaining chamber in a first operating phase and with a gas-liberating chamber in a second operating phase.
