HYDROGEN PRODUCTION DEVICE, HYDROGEN PRODUCTION METHOD, AND HYDROGEN PRODUCTION PROGRAM
A hydrogen production device (10) has a reactor (12) that thermally decomposes a hydrocarbon gas, which is a raw material gas, using a catalyst to produce hydrogen, wherein a fluidized bed of the catalyst is formed inside the reactor by introducing the raw material gas from a lower part of the reactor. The hydrogen production device comprises: a differential pressure sensor (43) configured to detect a pressure difference between an upper part of the reactor away from the fluidized bed and a lower part of the reactor corresponding to the fluidized bed; a supply device (21) configured to newly supply a catalyst to the reactor; an extraction device (31) configured to extract the catalyst with decreased activity from the reactor; and a control device (45) configured to control the operation of the supply device and the extraction device so that the pressure difference detected by the differential pressure sensor becomes constant.
