MOFs are emerging super-adsorbents with adsorption capacities up to 60% greater than conventional activated carbons or zeolites. This opens up highly promising prospects for strategic energy transition issues such as CO2 capture and the storage of energy carriers (H2, CH4, NG). However, these advanced capabilities are accompanied by equally significant inhibitory thermal effects (exothermic during adsorption, endothermic during desorption). On the scale of industrial applications, these effects can lead to significant drops in performance (in terms of capacity, selectivity and charge/discharge kinetics), as well as potential hot-spot hazards. Until now, although there has been a plethora of literature on MOFs, little research has been devoted to the management of these thermicity phenomena. The TEM-MOF project is entirely dedicated to them, bringing together a consortium of complementary partners around the various multi-disciplinary subjects involved. We are particularly interested in the development of conductive MOF/graphite composites to improve the performance of adsorption processes, such as CO2 capture in TSA processes. The 4-year project is divided between MOF and composite development, characterization, performance comparisons between MOFs and composites, multi-scale modeling and pilot application experiments. At every stage of the study, choices will be systematically made to reduce environmental impact.
