From the viewpoint of high-temperature energy transportation, a fundamental study of a chemical heat pipe which uses the SO2 /SO3 reversible thermochemical reaction is carried out in a closed system consisting of exothermic and endothermic reactors. For a relatively wide range of circulating gas flow rate, the gas composition, and initial temperature of the catalyst fixed bed, it is found that SO2 and SO3 of nearly equilibrium concentration could be circulated between the SO2-oxidation and the SO3-deoxidization reactors. Further, the possibility of continuous thermal energy transportation by use of this system was determined. The heat transportation characteristics of the system is made clear by the relationship between the heat flux released from the catalyst fixed bed and the molal velocity of SO2.
