An acetaldehyde/ethyl‐alcohol reversible hydrogenation and dehydrogenation reaction is proposed for a medium‐level heat transport system. Under atmospheric pressure the dehydrogenation converts heat at a temperature of 350–400°C to chemical energy. At another location chemical energy may be converted back, by the hydrogenation, to thermal energy at 200–250°C For both reactions, the same silica‐supported copper catalysts, particularly of ion‐exchange type, have high activities and selectivities. A small amount of ethyl acetate is produced. However, the reaction producing ethyl acetate is also exothermic, so that the acetate only slightly decreases the amount of heat to be transported with this system.
