Reactant in the form of granules for thermochemical systems

摘要

Reactant for thermochemical systems, including a support which is, for example, recompressed expanded graphite or vermiculite, and an active agent, for example a salt. According to the invention, the support is in the form of granules of graphite having a density of between 0.20 and 0.5 g/cm3 and whose diameter lies between 0.2 cm and 2.5 cm.
