Development of prototype fluidized bed reactor for solar hydrogen production

针对利用活性陶瓷作为高效氧化还原材料从水中制氢的太阳能热化学两步制氢循环，开发了利用高温太阳热能从水中制氢的流态化反应器样机并进行了试验。这种反应堆允许氧气和氢在反应堆内同时生产和分离。因此，该反应器可以在单个沸腾床反应器中实现连续两步反应的单一过程。在5kW太阳模拟器上进行的辐照试验表明，该工艺同时产生了氧气和氢气。我申请了一项国内专利，申请了使用该反应系统的太阳能热化学分解水生产氢气的方法和设备。

With regards to solar thermochemical two-step water splitting cycle using reactive ceramic as a highly-active redox material for producing hydrogen from water, prototype fluidized bed reactor was developed and tested for hydrogen production from water using high-temperature solar heat. This reactor allows that oxygen and hydrogen are simultaneously produced and separated inside the reactor. Thus, the reactor can realize a single-process of successive two-step reactions in a single fluidized bed reactor. An irradiation test by 5kW sun-simulator showed that oxygen and hydrogen were simultaneously produced in the single-process. I did an application for a domestic patent for method and device using this reaction system for solar thermochemical water splitting to produce hydrogen.
