PROBLEM TO BE SOLVED: To effectively give heat of gas after reaction to supplied reaction gas. SOLUTION: Heat storage sections 2a are arranged separately in stages in a regenerative heat exchange type condenser 2, and a cooling section 2b is provided thereunder. A high-temperature gas after reaction from a reaction tank 1 is introduced to the heat-storage sections 2a through pipes, so that heat is stored in heat storage materials 11. Reaction gas (carbon dioxide/methane) is supplied through a feed valve 3 in the lower part, and goes upward through the heat storage sections 2a. Reaction gas 7 heated by heat exchange is drawn by a pump 4 through an outlet 2c to be sent into the reaction tank 1. After undergoing reaction through heat exchange, the gas is cooked by a refrigerating section, so that moisture therein is condensed, and the remaining gas is returned to the regenerative heat exchange type condenser 2 again as the reaction gas 7.
