Provided are: a hydrothermal decomposition apparatus that uses an internally-circulating fluidized bed that can be reused by reliably separating and recovering oxygen and hydrogen that have been generated, arbitrarily controlling each of the reaction temperature, reaction speed, reaction time and reaction zone of reactions that simultaneously proceed in the fluidized bed, and recovering reaction heat with high efficiency
and a hydrothermal decomposition method. The hydrothermal decomposition apparatus is provided with: a thermal reduction reactor (3) for carrying out thermal reduction reactions
a hydrothermal decomposition reactor (4) for carrying out hydrothermal decomposition reactions
a dispersion plate (8) for introducing a low oxygen partial pressure gas to the thermal reduction reactor (3), and a dispersion plate (9) for introducing water vapor to the hydrothermal decomposition reactor (4)
an outlet (14) for recovering gas containing oxygen generated by the thermal reduction reactor (3)
and an outlet (15) for recovering gas containing hydrogen generated by the hydrothermal decomposition reactor (4). The hydrothermal decomposition apparatus is configured in such a manner that a top communication port (6) and a bottom communication port (7), which are formed on a partition plate (5) that partitions the thermal reduction reactor (3) and the hydrothermal decomposition reactor (4), are buried inside the fluidized bed (2), and the fluidized bed (2) is able to directly flow between the thermal reduction reactor (3) and the hydrothermal decomposition reactor (4) through the top communication port (6) and the bottom communication port (7).
