Abstract: Adsorption heat transformation is an environment and energy saving technology for effective utilization of low-temperature heat sources. Recently, a novel adsorption cycle, so-called “Heat from Cold” (HeCol), has been suggested for upgrading the temperature of the ambient heat in cold regions up to higher level suitable for heating. This paper addresses the new composite sorbent of methanol LiCl/Verm, based on LiCl inside expanded vermiculite pores, specialized for the HeCol. The equilibrium and dynamics of methanol sorption on the LiCl/Verm was studied under conditions of the HeCol cycle, and its potential for utilization in HeCol cycle was evaluated in term of the heating capacity. The main findings are as follows: 1) the amount of methanol cycled at the HeCol cycles reaches 1.0-1.6 g/g that far exceeds that for other adsorbents; 2) the heating capacity of the LiCl/Verm varies from 1.3 to 2.0 kJ/g under conditions of different HeCol cycles that is of high practical interest.
