项目摘要

In the development of solar reactor for O2-releasing with Ni-ferrite (reactive ceramics), the two-step water splitting can be successfully proceeded repeatedly by temperature swing between 1473-1773K. For the Zn-ferrite system, a new solar reactor is designed based on the concept of recovering the powder mixture of ZnO+Fe3O4, and fabricated the practical testing instrument with a high temperature heat, for enhancing the reactivity of the Zn-ferrite system.With this experiment, it was found that the solar reactor adopting the Zn-ferrite system can be developed for proceeding the O2-releasing process at the temperature around 1573K. Also, the cylindrical rotary reactor was newly designed and fabricated, with which the O2-releasing and H2-generation steps can be continuously repeated using infra red imaging furnace. It was confirmed that the cylindrical rotary reactor can work with a high efficiency for the two step water splitting process.The optical system of the tower solar concentration plant was designed, and it was found that 3000 concentration can be obtained at the high solar angle, even though 2700 concentration is at least required, for the practical requirement of 2000 solar concentration.When the endothermic reaction proceeds, 6.22mol/m2 of YSZ01NF is consumed for 2000kW/m2 of the beam flux, indicating that the thickness of the solid reaction bed is several cm for the dual type solar reactor (cylindrical rotary reactor). Thus, combining the newly developed reactive ceramics of YSZ01 NF and the dual type solar reactor, the solar hydrogen production can be realized by making the best use of a high solar beam flux through the solar/chemical energy conversion.

在使用Ni-Ferrite（反应性陶瓷）释放的太阳能反应器的开发中，可以通过在1473-1773K之间的温度挥杆来成功进行两步水分裂。 For the Zn-ferrite system, a new solar reactor is designed based on the concept of recovering the powder mixture of ZnO+Fe3O4, and fabricated the practical testing instrument with a high temperature heat, for enhancing the reactivity of the Zn-ferrite system.With this experiment, it was found that the solar reactor adopting the Zn-ferrite system can be developed for proceeding the O2-releasing process at the temperature around 1573K.同样，圆柱旋转反应器是新设计和制造的，使用Infra红色成像炉可以连续重复使用O2释放和H2代的步骤。据证实，圆柱旋转反应器可以在两个步骤的水分分开过程中具有高效率。设计了太阳能浓度厂的光学系统，并且发现可以在高太阳角度以高太阳角度获得3000个浓度，即使至少需要2700个浓度，即使对2000 Solar浓度的实际需求至少需要2700个浓度。用于2000kW/m2的梁通量消耗，表明固体反应床的厚度为双型太阳反应器（圆柱旋转反应器）的几cm。因此，结合了YSZ01 NF的新反应性陶瓷和双型太阳反应堆，可以通过通过太阳能/化学能转换率充分利用高太阳束通量来实现太阳能氢的产生。
