Development and demonstration of rotary-type solar chemical reactor

开发了“后加热系统”和“交叉线性系统”的新型太阳能聚光系统，合成了高活性陶瓷YSZ/ ni -铁氧体固溶体。快速加热αO_2释放反应经过两个步骤：1)光子吸收及其弛豫过程形成过量的Frenkel结构（光反应）；2)缺陷结构能驱动晶格氧生成O_2气体（暗反应）。制作了双柱太阳能反应器（3_<rd>型），可连续进行明暗反应。所研制的旋转反应器在CSIRO太阳能场进行了现场试验。

New solar concentration systems of "post heating system" and "cross linear system" were developed, and highly reactive ceramics YSZ/Ni-ferrite solid solution was synthesized. TheαO_2 releasing reaction by rapid heating proceeds via two steps of 1) photon absorption and its relaxation process forming an excess Frenkel structure(light reaction), and 2) O_2 gas formation from lattice oxygen, which is driven by defect structure energy(dark reaction). The dual column solar reactor(3_<rd> model) was fabricated, with which the light and dark reactions can be occurred continuously. The field test of the rotary reactor developed was done at the solar field of CSIRO.
