抄録

Storing and temperature upgrading of heat energy at 773 K by means of a CaO-CO<SUB>2</SUB> reaction seems very attractive. One way of storing the reaction product CO<SUB>2</SUB> gas is in the form of an other carbonate by letting it react with a metal oxide, such as MgO or ZnO. Two metal oxides, MgO and (CaMg)O<SUB>2</SUB> were selected for CO<SUB>2</SUB> storage, with the CaO-CO<SUB>2</SUB> energy storage system as CaO-CO<SUB>2</SUB>-MgO and CaO-CO<SUB>2</SUB>-CaMgO<SUB>2</SUB> systems, and studies on CaO-CO<SUB>2</SUB>, MgO-CO<SUB>2</SUB> and CaMgO<SUB>2</SUB>-CO<SUB>2</SUB> reactions over the temperature range 773–1073 K were carried out. As the CaO-CO<SUB>2</SUB> system is used not only for storing the heat energy but is also expected to perform as a heat transformer, verification of the temperature upgrading ability is made by means of a lab-scale adiabatic reactor. Pseudo-steady state temperature and pressure existed during the experiments, which correspond quite well with Haul's equilibrium dissociation values of CaCO<SUB>3</SUB>, illustrating that upgraded temperatures of above 1273 K can be achieved by adjusting the carbonating CO<SUB>2</SUB> gas pressure to around 500 kPa.
