| Research Abstract |
A windowed internally circulating fluidized bed reactor was developed for solar thermochemical two-step water splitting to produce hydrogen from water, and tested using reactive ceramic of zirconia-supported iron-based particles as highly-active redox material by solar-simulated Xe light radiation through a transparent quartz window mounted on top of the reactor. The feasibility of successive two-step water splitting using the fluidized bed reactor was examined by switching from Nitrogen gas flow in the thermal reduction step to a steam/Nitrogen gas mixture in the water decomposition step. It was confirmed that hydrogen production takes place in the single fluidized bed reactor by successive two-step water splitting.
